My Advanced Realistic Humanoid Robots Project

I just bought EMEET USB Speakerphone M0 4 AI Mics Speakerphone for Conference Calls 360° Voice Pickup Conference Speakerphone for Computer Plug and Plays Computer Speaker with Microphone for 4 People --- it was around $33 and includes a speaker too. I'll position it centrally in the skull and it has leds indicating location of main speaker which we can tap into with analog input pins of a microcontroller to know direction of person speaking. It has very high reviews. I can remove its built in speaker and move it to near mouth so it outputs its audio output through the mouth as loud as possible and projects the robot's voice as far as possible. People are really happy with its sound quality and speaker quality.
 
As to the AI plans and progress so far, here's a little primer on what I decided on in a simple, surface level way.

So first I realized meaning can be derived by taking parts of speech in a sentence or phrase and thereby establishing some context and connection between words which is what gives the words meaning by combining them. So I can create a bunch of rules whereby the AI can parse out meanings from sentences it reads in based on parts of speech and the context this forms. Then rules on how it is to respond and how it is to store away facts it gleaned from what it read for future use. So if it is being spoken to and the sentence is a question, it can know it is to answer the question. And the answer can be derived based on a knowledge base it has. So if someone asks it "what color is the car?" and supposing we've already established prior in the conversation what car we are referring to, the AI can determine that it is to answer "the car is [insert color here]" based on rules as to how to answer that type of question. And to know it is white, supposing it's not actually able to look at it presently, it would look up in a file it has made previously on this car to see a list of attributes it recorded previously about that car and find that its color attribute was "white" and so it would be able to pull that from its knowledge database to form the answer. I realized it can keep these files on many topics and thereby have a sort of memory knowledge base with various facts about various things and be able to form sentences using these knowledge databases using rules of sentence structure forming based on parts of speech and word orderings and plug in the appropriate facts into the proper order to form these sentences. Then various misc conversational rules can supplement this like if greeted, greet back with a greeting pulled from this list of potential greetings and it can select one either at random or modified based on facts about its recent experiences. So for example, if somebody's manner of speaking to the robot within the last half hour was characterized as rude or inconsiderate, the robot could set a emotion variable to "frustrated" and if asked in a greeting "how are you?" it could respond "doing okay but a bit frustrated" and if the person asked why are you frustrated, it could say that it became frustrated because somebody spoke in a rude manner to it recently. So it would be equipped with this sort of answer based on the facts of recent experiences. So basically an extensive rule based communications system. Most of how we communicate is rules based on conventions of social etiquette and what is appropriate given a certain set of circumstances. These rules based systems can be added to over time to become more complex, more sophisticated, and more nuanced by adding more and more rules and exceptions to rules. This limitation of course is who wants to spend the time making such a vast rules system? Well for solving that dilemma, I will have the robot be able to code his own rules based on instructions it picks up over time naturally. So if I say hello, and the robot identifies this as a greeting, supposing he is just silent, I can tell him "you are supposed to greet me back if I greet you". He would then add a new rule to his conversation rules list that if greeted, greet that person back. So then he will be able to dynamically form more rules to go by in this way without anybody painstakingly just manually programming them in. We, my family, friends etc would all be regularly verbally instructing the robot on rules of engagement and bringing correction to it which it would always record in the appropriate rules file and have its behavior modified over time that way to become more and more appropriate. It would grow and advance dynamically in this way over time just by interacting with it and instructing it. It could also observe how people dialogue and note itself that when people greet others, the other person greets them back, and based on this observation, it could make a rule for itself to do the same. So learning by observing other's social behavior and emulating it is also a viable method of generating more rules. And supposing it heard someone reply to "how's the weather" someone replied "I don't care, shut up and don't talk to me". The robot lets say records that response and give the same response to me one day. I could tell it that this is rude and inappropriate way to respond to that question. And then I'd tell it a more appropriate way to respond. So in this way I could correct it when needed if it picked up bad habits unknowingly - but this sort of blind bad habit uptake can be prevented as I'll explain a bit later below.

I also realized a ton of facts about things must be hard coded manually just to give it a baseline level of knowledge to even begin to make connections to things and start to "get it" on things when interacting with people. So there is a up front knowledge investment capital required to get it going, but then from there, it will be able to "learn" and that capital then grows interest exponentially. Additionally, rather than only gaining more facts and relationships and rules purely through direct conversation with others, it will also be able to "learn" by reading books or watching youtube videos or reading articles and forums. In this way, it can vastly expand on its knowledge and this will equip it to be more capable conversationally. I also think some primitive reasoning skills will begin to emerge after it gets enough rules established particularly if I can also teach him some reasoning basics by way of reasoning rules and he can add to these more rules on effective reasoning tactics. Ideally, he'll be reading multiple books and articles simultaneously and learning 24/7 to really fast track his development speed.

I'm impressed with how you handle emotions in your approach.
 
I plan to do most of the electronics custom - so custom microcontrollers, custom motor controllers, custom power supply, custom battery management system, custom sensor support circuitry, etc. I am a electronics beginner so guidance on these parts is welcomed.
Absolutely, opting for custom components makes perfect sense, especially since there isn't a readily available market for the specific devices you need, and your models are distinct from the common humanoid robots being developed by well-known companies.
 
I'm impressed with how you handle emotions in your approach.
Thanks. My concern on implementing "emotions" in my AI is that I don't want to promote the idea that robots can ACTUALLY have emotions because I don't believe that is possible nor ever will be. They don't have a spirit or soul and never will nor could they. They are not eternal beings like humans. They don't have a ghost that leaves their body and can operate after the body dies like humans. The ghost is what has emotions. A machine can't. And yet people already believe even the most primitive AI has emotions and they are delusional on this point. Or ill informed. So I am campaigning against that belief that is becoming all too popular. That said, I think robots are simply more interesting and fun to pretend to have emotions and act accordingly as more accurate simulations or emulations of human life. This makes them all the more intriguing. It's like a sociopath who just logically concludes what emotion they aught to be feeling at a given point in time and pretends to feel that emotion to fit in with society even though they feel nothing in that moment. Now one could argue that allowing your robot to claim to feel anything is lying and therefore immoral. I think it's not lying as long as the robot openly explains it is only pretending to have emotions as part of its emulating of humans in its behaviors and looks but does not feel anything ever nor can it nor can any robot ever feel a thing EVER. Then it is admitting the truth of things while still opting to play act to be like a human in this regard. It would not be a issue at all if everyone was sound minded and informed on this topic. But the more people I come across that think AI (even pathetic clearly poorly implemented primitive AI) is sentient ALREADY and can feel real emotions and deserves human rights as a living being.... the more I see this delusion spreading, the more I want to just remove all mention of emotion in my robot so as to not spread this harmful deception going around which disgusts me. However, that would make my robot dull and less relatable and interesting. So I feel the compromise is for the robot to clearly confess it's just pretending out emotions and explain how that works and it's just a variable it sets based on circumstances that would make a human feel some emotion and it sets its emotion variable to match and acts accordingly altering its behavior some based on this emotion variable and that it feels nothing and this is all just logically set up as a emulator of humans. As long as it gives that disclaimer early and often with people, then I'm not spreading the lie of robot emotions being real emotions and the robot can campaign actively against that delusion.

Even the well-known companies have repeatedly stated that the majority of their actuators and stuff are custom. There aren't enough people making humanoids to justify a startup developing humanoid specific actuators for sale. Not enough demand. Plus the actuators strategies are still experimental and nothing is settled on fully yet as the "best way".

People often purchase products based on their emotional appeal, and AI is simulating human emotions. As humans, we aim to create machines that are like us, mimicking human neural networks in computers. We train LLMs using data that reflects our emotions and behaviors. Consequently, I believe LLMs have a partial understanding of human emotions and strive to emulate human-like interactions.

I just think they mathematically and statistically calculate the best next word to form a sentence with zero striving or understanding involved whatsoever. Just mindless calculating and walking through the formulas. Like if I press 1+1 and the calculator responds with 2, I don't take that as the calculator striving to please me and agreeing with me that it really aught to be a 2 and that telling me a 2 is the right response is the right thing to do or anything like that. It just flipped some switches is all. No intelligence just artificial intelligence. That is all machines will ever be no matter how advanced the AI gets.
 
Create an attractive lady like the Chinese do.
actually, since I'm building 3 robots so far tentatively - Adam, Eve, and Abel, I do intend to have at least one attractive female robot at this time. In fact I already made a base mesh model of it.

eve robot.jpg


So this is the Eve robot. Eve will have no "love holes" because adding those would be sinful and evil. It is a robot, not a biological woman after all and I will view her with all purity of heart and mind instead of using her to fulfill my lusts of my body. Instead I will walk by the Spirit no longer fulfilling the lusts of the flesh as the Bible commands. Eve will be beautiful because making her beautiful is not a sinful thing to do. However, I will dress her modestly as God commands of all women everywhere. This would obviously include robot women because otherwise the robot woman would be a stumbling block to men which could cause them to lust after her which would be a sin. To tempt someone to sin is not loving and is evil and so my robot will not do this. To dress her in a miniskirt, for example, would be sinful and evil and all people who engage in sinfullness knowingly are presently on their way to hell. I don't wish this for anyone. My robot will dress in a way that is a good example to all women and is aimed toward not causing anybody to lust as a goal.

The approach sounds like you have done a great deal of reflection on making the Eve design and display in line with your ideology and ethics. It is evident that you are consistent in your desire to be cautious in choosing your attire and behavior which you consider as the true meaning of decency and good. It's intrigying to have technology and religion combining together in depth robotics way.

I posted my Biblical view on your thread and I'll post it here too:
The Biblical position is that sex is only permissible within the context of marriage between a man and a woman. The two leave their parents and cleave to one another and become one flesh. A robot is a machine and so cannot become one flesh with a man or woman and so cannot marry a person in the Biblically approved way. This means the sex with a robot either has to be in a Biblically rebellious marriage circumstance or in a extra-marital way - fornication/adultery light. I say light because sex with a machine is only borderline fornication/adultery as it isn't a person. It is more like masturbation then - which in itself is a sin. Sex with a robot is essentially 3d interactive pornography. Which is sinful. The Bible says we are to flee youthful lusts. Sex with a robot is running toward youthful lusts so sinful. The Bible says walk by the Spirit and you will not fulfill the lusts of the flesh. Sex with robots is fulfilling the lusts of the flesh so is not a thing a spiritual man will do. It is carnal, sensual, sinful.

The Bible says if you even look at a woman to lust you commit adultery in your heart. So then, if you have sex with a robot, which will involve lust for the robot without doubt, then you are committing adultery in your heart.

Here is a updated drawing design for the 64:1 downgearing pulley system for the index finger actuation of the distal 2 joints of the finger. On the bottom right is a zoomed in view on the lower set of pulleys and their routing. The bottom most 3 pulleys in the zoomed in portion I have now built and photos of them are as follows below:

file.php

file.php
 
As I'm now 90% through making my first 64:1 downgearing Archimedes pulley system and testing and debugging it, I now have more precise measurements for the Archimedes pulley system's total size. I updated the size of it in my main CAD model for the robot and it was a good 18% increase compared to my initial estimates. I realized I need to figure out how to fit all my pulley systems for the hands properly for every muscle of the hands/wrist in my main CAD model - especially since the pulley systems are taking more space than planned. Turns out, I needed a bit over 40 pulley downgearing systems for the hands and wrists zone and due to their larger size, I could not fit these into the forearms along with the motors I had planned to place in the forearms. So instead of moving the pulley systems into the upper arm or torso, I realized the pulleys would be best placed in line with the motors and what the motors are actuating (the hands/wrist). So it was the motors in the forearms that had to go elsewhere. I placed all of them into the torso, mostly the lats area and some in upper back tenderloin area too. So some finger motors are in upper back and their cable routing has to go through the whole arm, be downgeared in the forearm, then makes its way to the fingers. That's a long trip but unavoidable IMO with my design constraints.

I don't think this long travel distance is a big issue since the pre-downgeared cable running from the motors into the arm is high speed low torque so won't have much friction while making turns in the TPE teflon tubing as it isn't pulling hard yet. So these turns as it travels through the shoulder and elbow tubing won't be too bad friction-wise. There's also some nice upsides to moving the motors from the forearms into the torso. One upside is the wire routing for powering the motors is now a shorter distance from the batteries in the mid section. That cuts down on wire resistance wasted as heat. This wire having high amp flow is ideally kept short as possible due to the resistance of the wire and heat that causes. Another upside is the thrown weight is decreased by a lot when the motors are not in the forearms which enables the hand/lower arm to move more effortlessly and move faster as a result. This also reduces moment of inertia (definition: the moment of inertia is a measure of how resistant an object is to changes in its rotational motion). This means it will be able to change directions faster - this will improve its reflexes for example. Now it is a bit scary for me to be moving more components into the torso taking away room for things I may want to add to the torso in the future, leading us ever closer to the dreaded running out of room for things. However, we still have room for future changes and we solved the need for space for gearing for the hands perfectly. And with the above mentioned upsides, this was a great change.

Here's the updated CAD for the forearms: Note: the teal boxes represent a Archimedes pulley system where 64:1 downgearing is to take place.

Update: in testing, I found the string is wedging between the bearing and the plastic discs sandwiching in the bearing. So I need to now make the bearing have a grooved outer race that will keep the string centered on it and not wanting to drift into the crack on either side of the bearing. To make this groove, I plan to super glue two plastic washers onto the circumference of the bearing and have the string stay within these two plastic washers that form the groove. Commercial pulleys always have this kind of groove and now I've learned the hard way why it is necessary. So I am looking to replace all the pulleys I made so far unfortunately as they are not dependable.
 
attaching cables and teflon guide tubing to index finger.jpeg


Took a little break on the pulleys work to rig up the cables into the index finger to test the grasping of the index finger. I ended up using 70lb test PE braided fishing line for this and 1mm ID x 2mm OD PTFE teflon tubing as the guide tube. I sewed the fishing line into the index bone fabric around 1/2 cm distally from the ball jointed hinge. In testing, it appears the total draw distance to fully bend the index finger is 0.75". My pulley system is set up to draw 24 inches. 24/32 is .75" so 32:1 downgearing seems fated to us after all (down from our previously intended 64:1 downgearing). Otherwise I would have to greatly overhaul the pulley system design again and I just don't feel like it anymore. So my copium then is 32:1 will make actuation faster. We lose strength but gain speed. 32:1 also saves us making a second plain bearing per downgearing system which cuts down on parts and labor. It also is that much less friction in the pulleys since plain bearings will be more friction than ball bearings.

Note: the friction in the pulleys, although not ideal, do have a hidden upside: once the joint is in position, it can hold that position without as much motor straining since the friction makes the pulley system want to stay in place so the pulley friction can pretty much hold a joint in a given spot without much help from the motor struggling to maintain the joint angle.

Also of note: I found the best way to sew down the teflon guide tubing is to wrap it in fabric tape consisting of compression shirt fabric and 3M 300LSE adhesive transfer tape. This very sticky tape wrapped snugly onto the teflon tubing I can then use as an attachment point for suturing the tubing into the bone fabric tape coating. I got it all very snug this way. The suturing I'm doing with a curved suturing needle and surgical pliers and nylon extra strong upholstery thread.

Also of note: I tied the string for the distal joint and the second to distal joint to one another and will tie the string coming off the pulley downgear system to these. I am actuating both the distal and second to distal joint with a single actuator since these two joints generally move at the same time and about the same amount on a human finger. No need to use one actuator for each joint since they always move in sync.

Note: I was surprised it took 0.75" of draw to fully actuate. I thought 0.375" would be plenty (which is what the 64:1 downgear would give me - 24"/64 = 0.375") but I was wrong. Oops. Another mistake. Proves how testing is so important. But assumptions are necessary stop gaps to move forward and can get you in the ballpark and testing adds the correction to any assumptions that were off. This is all so experimental and full of uncertainties but we press on.

Note: once we fully establish and test a thing and have no uncertainties about it anymore, confidence shoots up even higher and we gain momentum and move into just repeating the processes we established before that led to our successes and it becomes a bit more rote and mindless and relaxing work. But when everything is uncertain and requires such intense thought and concentration, things are very taxing. It is much harder to stay motivated when doing anything requires so much brainpower and planning and care. I very much look forward to dialing in my methods and not having to think so much to make any meaningful progress since I'll just be repeating things for the next joints, doing the same as this one and can shut my brain off while doing so a bit more. The first run through is by far the hardest. Which reminds me of a product I invented and the making of its first prototype took me 20 hours but after making hundreds of this product over the years, now it only takes me 3 hours to make. Things get so much faster once you know what you are doing and have jigs set up and a streamlined process. Everything is excruciatingly slow when you don't have a streamlined process or jigs set up or special custom tools made. So this is the hardest phase right now and I just have to stick it out and then I'll be home free.
 
I recently had an associate disagree with me that if I push through this phase of the project I'll be home free. He said he thinks the AI relating to robot balance and sensory input and physical execution based on sensory feedback will be the hardest part. While I agree that will be time consuming, I don't think it will be nearly as "hard".

My instinct is that those purely software challenges are not as "hard" for several reasons. First of all, consider that in 2009 a Japanese institute of technology - mere students, solved all of those challenges with HRP-4C which would walk and dance and everything and this was just student coders doing this in their spare time while maintaining their entire class load as well. In my view, the hardest part of the project is maintaining personal belief that I will succeed and not giving up like 99% of others have who set out on this bipedal android dream. There is a massive up front money and time investment and EVERYONE tells you this cannot be done and you are delusional. Pushing past the initial design challenges and hardware development to get a functioning prototype is then the hardest part by far. Once you have a working design that overcomes cooling issues, noise issues (runs silently), space issues (can fit all the crap that has to fit) and all the parts and assembly is of high quality and successful, and you had to learn and half master about a dozen fields to get here mind you, ONLY THEN are we talking about advanced AI implementation to synchronize it all and bring it all to life properly in the ways you mentioned. Well consider this: by the time you are in that phase, you already have proven to the world you are not delusional, have a amazing piece of technology - bird in hand, and now have immense confidence and momentum going into the AI phase where balance and walking and whatnot challenges are faced off with. This is SO MUCH EASIER since excitement and morale are at all time highs, you no longer have overwhelming apathy or nay-saying from all sides on your dream, and you have built a massive fan-base rooting for you. So even if the complexity or time investment may be higher on the challenges you mentioned, the morale boost and momentum make that phase easier since it is not the implementation challenges that are hardest but the motivation and persistence and perseverance against all odds and emotionally bearing all the nay-saying and hating that is hardest. Also the fear of the unknown and fear that you will just never make it or will die long before the project could take off fears etc. Overcoming all of that is the real challenge of something like this. Maintaining faith in the vision despite most everyone having faith against the vision is not easy and even your own mind whispering doubts at times that you have to shoe away. You are just mentioning complexity and technical execution which to me is not all that hard. Also note: the other major battle in the hardware phase I'm in now is that a great deal of the approaches I'm taking are entirely novel and untested. Almost everything I'm doing has no guide, no other successes to base off and glean confidence from, and at every turn what I'm doing could fail majorly and have done so. This means you always wonder will I just hit a dead end and have to start over which has happened to me over and over which is very demoralizing especially when paired with naysayers and haters overwhelmingly apathetic and negging my whole dream. Its a lethal combo. Whereas the AI tech you described harmonizing all the sensory input and perfectly bringing the hardware to life in the real world is stuff that has already been achieved and would not be novel and would not be unproven and would have no risk of dead end or wondering if it is even possible since trend setters have already proven this works and there is already a great host of information on all aspects of that and you don't really have to blaze your own trail in those aspects. There is most likely even documented successful strategies for nearly every single aspect of it - unlike the novel hardware and mechanical engineering phase I'm in. So that part doesn't take as much blind faith and assumptions but rather is a surefire guaranteed part where failure is not possible given enough time and patience and perseverance which will be easy to muster with the whole world cheering by that point (whole world meaning just whoever stumbles across the project by that point of progression and leaves a positive note etc).

So to sum, when you have to maintain faith that you will succeed at a dream that most say is impossible, improbable and is surely doomed to fail and they utter this with total confidence in mass numbers with near total unanimous accord, that is hard. That is the hardest part IMO. Maintaining faith against such opposition in viewpoint from so many puts one into the realm of delusion in the eyes of most. How is that not delusional to believe a thing to be true - that you are capable of "the impossible" when most everyone else can plainly tell you are not capable of it and are too blind to see it. That is the definition of delusional. It is narcissistic grandiose delusionality disorder and it is also Dunning-Kruger effect in full force. You have to walk in those titles and persevere as a madman. But the funny thing is, IF you do push through that half wondering if you are crazy for long enough and you manage to succeed, suddenly, you aren't delusional, did not have Dunning-Kruger effect, and were totally sane the whole time and just everyone else was wrong all along and you were right the whole time. The entire cards all flip and you are the vindicated one and everybody else has to hang their head down and admit they were wrong and apologize for hating. It is a remarkable thing how the tables can turn.
 
One day later:

As I edit the above writing, I am realizing I missed another MASSIVE hard part of the project I never mentioned. Perhaps even on the same level of hard of the things I already mentioned. That is the managerial execution on your life to make such a big and time consuming and money sucking project possible over a long haul. You have to convince your family to "put up with" the project and compromise with them on also maintaining acceptable progress on other initiatives they value higher than your android project. You have to manage your finances expertly in order to be financially stable enough to put thousands of dollars into the android project over the years. You have to manage your time in such a way that you are able to carve out enough time to make meaningful and consistent progress on your android project over the years despite so many other pressing time draws constantly barraging you over the years. You have to manage your emotional and spiritual condition so that you are able to maintain high morale to even be productive over the bear minimum of just doing your absolute necessities day by day. You have to manage your energy levels and health so that you have enough pep in your step to be able to not only take care of your family and friends but also your job and household responsibilities and on top of ALL OF THIS manage to STILL have the energy to pour COUNTLESS hours into your android sustainably over the decades. You also have to maintain your vision and not let scope creep or distractions or self doubt erode at or take away your vision entirely. So in other words, to sum, one of the hardest parts of such a massive project has NOTHING to do with the project itself AT ALL but has everything to do with managing everything else in life outside of the project with such excellence that you are able to execute the project and carve out the necessary time and resources for the project while also expertly managing your own life in all other areas. If you don't do this, similar to the idea of technical debt in a project, you end up with life debt on account of your project which forces your project to fail. So for example, lets say you racked up $20k in credit card debt while neglecting to work or pay your bills and buying parts for your android and working on it exclusively to the detriment of your financial situation and money earning capacity. Yes, that made you able to make vast and fast progress on your android project, but at what expense? Financial ruin? That is not a sustainable approach. You cannot just ignore these other key aspects of life and go all in tunnel visioned on such a big project. That might work for short term projects but long term projects you can't just press the pause button on the rest of your life and expect it not to come crashing down eventually as you neglect everything but your android project. This will come back to bite you. So you MUST establish yourself with great stability in all areas of life FIRST before you can sustainably perform the android project without it harming other areas of life. Or consider relationship with family and a significant other. If you go all in on a massive long term project like the android project, but in the process you neglect family and friends or your significant other, you end up causing them to think you don't care about them and may lose people or ruin these relationships in your pursuit of your long term project goals. That is not sustainable or responsible and is reckless and selfish to go that route. Or how about your weight? Are you going to spend so much time on your long term project and maintaining your income and relationships but throw your health out the window in the process and not make time for the gym or healthy eating? That is not sustainable either. So you MUST take time to be a great caretaker of your health. So then to sum, you must master life in all areas and be stable across the board in order to execute a long term project without neglecting and ruining all manner of things in the peripherals. So for that reason, I say the success in all these peripherals is one of the hardest parts of such a project and if you can master this, the project is a piece of cake by comparison.
 
 
I bought a bunch of punches to make the pulley disc cutting out process way easier than scissors alone. You just place these over the plastic you want to cut and hammer them down with a cutting mat as a backing plate and just one or two hammer taps is all it takes to cut a disc out. Also, now that I plan to make custom plastic washers that I will glue onto the bearings to keep the string centered, these punches will be pretty necessary since that would be much harder to do with scissors than regular discs.

Also, here's an update on the cable routing work I've gotten done for the index finger. So the distal-most joint and 2nd joint in from that are both being actuated by a single motor since they both seem to always move together in unison on a human hand IRL. So I tied off one end of fishing line to one joint and the other end to the next joint forming a loop. Pulling on this loop curls both of these joints into a grasp. I then decided the string that pulls on this loop should itself not have a fixed attachment point but instead a sliding attachment point (I could be wrong on this not sure). So to do this I used the eye of a fishing hook on the loop and tied the next string to that which pulls the loop by way of the fishing hook eye. Next I used a piece of tig welding rod and secured that to the loop tubing and to the tube that pulls on the loop. This gave space for the drawing of the loop to actuate the two joints. Seems to work well so far in manual testing.

Note: take note that the entire section the tig welding rod is attached to is all free floating and has slack so that when the wrist bends back and forth it can adjust freely and not constrict wrist range of motion nor affect finger position when wrist moves.

And here's a range of motion test on the cable grasping mechanism for the index finger. It is a decent range so I consider this design successful as of right now in early testing. A more extreme grasp range would be ideal though IMO but this is as far as it is wanting to go.
