So today I went ahead and extracted this metal skeleton from a male love doll I had bought some months back to use as a base form from which to sculpt the appearance of another robot. Just to clarify upfront, this was never purchased for any sexual purposes—strictly for its materials. I bought...
TheRobotStudio on YouTube is doing an open source robot called "Hope-Light" and inviting his viewers to follow along with his progress . I have decided to follow along, although I will be modifying his designs as I go to customize it more to my liking. He expressed he wants this to be a open...
I came up with a design for a way to do all my downgearing 64:1 by way of pulleys that is so downscaled that it can fit onto the top of the 2430 motor and achieve the full 64:1 downgearing for BOTH directions of travel.
Here's a photo of the design drawing I made which roughly approximates what...
By popular demand, here is some math I did regarding the motor and pulleys for the finger actuation.
64:1 downgear ratio
24 inches total draw onto motor shaft 24 / 64 = 0.37" draw at finger joint
2430 motor 5900kv at 12v RPM = kV * V RPM = 5900 * 12 RPM = 69600
69600 / 60 = 1160 revs/second...
Ok so my solution is to sew a fishing hook's eye into the bone sleeve snugly with upholstery thread as a anchor point. Then I will draw my braided PE fishing line through this eye and back down. Instead of tying it off with a fancy knot which acts as a weak point or concentrated stress point, I...
I finished fixing the fishing line on the bottom-most pulley with 5 knots this time to make sure it doesn't untie. I hung the 10lb dumbbell from the pulley system and to my horror, two fishing line points snapped almost immediately in two new spots. These fishing lines were rated 20lb test and...
With my existing snatch block and block and tackle style pulley systems tested and working decently at 16:1 downgearing ratio which feels pretty complex and capped out by space constraints, I am now turning my attention back to some prior concepts for rotating in place pulleys I had planned...
Sorry for the long wait. Got busy with other stuff. Anyways, I completed the full pulley system and just got done testing it. It did not snag once anymore (rope binding between pulley and flanges) because each spot prone to that issue I fixed by putting some clear thin fishing line across that...
Yeah just a few laws is too simple to form a entire ethics system. God's laws laid out in the entire Bible are much more thoroughly laid out and form a much more sound ethical system foundation which is why I will be basing my robot's ethical decision making systems on them. They are more...
I'm impressed with the explosion of new companies pursuing humanoid robotics. It is an exciting time for me seeing this. I've never seen anything like it. The most groundbreaking development IMO would be affordable humanoids that buyers can program and add their own capabilities to. Although...
Man these guys are moving at lightning speed. Figure 1 just came out it feels like. Must be an amazing team and exciting to work there seeing this kind of fast development.
So the pulleys were working fine except occasionally the thread would wedge between the plastic discs and the bearing causing the system to jam. My solution originally was to cut out finger nail clipping shaped pieces of thin clear plastic to glue onto the inner face of the discs that contain...
you could use 2 servos for motor 1 and 2 to double it and you could mount motor 2 servos off the arm on the base and use a cable/tendon based actuation method where fishing line goes from servo horn through tpfe tubing to the joint and this takes all weight off the arm and puts it on base so arm...
IMO you'd want a 3d environment containing a model of the robots body in its current position and joint angles as well as any momentum information being considered, and a 3d model of the environment. You'd put in collision boxes in this 3d environment like a videogame has for objects. You'd...
A colleague pointed out that the robot probably will need massive batteries. I agree with this in part, but with some caveats. Yes, to support the massive number of motors and the large bursts of energy required when most motors are firing all at once during rigorous athletic type activities...
A colleague of mine expressed concerns over how I will deal with the heat generated by the motors and other electronics. He pointed out that all these motors are going to generate heat while running and the silicone skin will prevent that heat from escaping. This was a great observation and...
for a humanoid with skeletal structure as the frame, in my exploration, low torque high speed motors typically used for drones or scooters are the best priced due to economies of scale and their high demand. The downgearing I theorized is best done by way of pulleys to keep it silent and they...
A colleague of mine asked why I'm using Windows for the robot's brains instead of Linux. Well, in my experience, if you set a program on windows to real-time priority or even above normal priority, it will give most of the processor over to that process and act like a real time operating system...
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...
