Solar powered humanoid robots does sound rather intriguing, although there are a few points to ponder about concerning the practicality factor. First and foremost, the energy that is needed for the functioning of a humanoid robot is fairly high. The current efficiency of solar panel might not be adequate to provide the required power, especially for robots that have high expectations to perform various functions, or those that need to work in areas where access to sunlight is limited.
In this case, although the space on a humanoid robot body can be utilized for solar panels, the exposed area is limited. This decreases the available amount of solar energy, so while these robots might need additional means for replenishing their power supply or larger solar panels which are not as maneuverable, the overall solar energy is reduced.
Budget constraints may indeed make this very unachievable in the near future, but improvements in Solar technology and energy storage may help in the future. Rising in the area density and innovative solar cell technology along with enhanced battery technology would enable to counter these challenges. However, fields that integrate photovoltaic system in cooperation with other renewable energy or conventional power types might be reasonable.
Globally, today’s humanoid robots may not be entirely dependent on solar power for energy supply but, in the years to come, renewable solar energy’s part can be a strong foundation in supplying the needs of the robot world.
