Brains:
I believe the ultimate “brain” for a robot would consist of multiple “brains” interconnected via wifi, bluetooth, &/or hardwiring. They would share processing, ram, and a common memory bank.
At least 3 tablets would make up the primary or master brain spaced out within the torso. Additional devices as slaves would be located in the base and extremities. These would receive basic instructions (“pick up the glass”) as well as keep up to date with the robot’s position and carry out the command with built in programming assisted with onboard sensors within its own extremity.
Using cell phones and tablets makes sense because they already have wifi, bluetooth, cellular service, gps, orientation/motion sensors, vision, and audio built in.
Skin:
The nanotube based skin is itself a network of sensors. At least one article describes it having the ability to detect not only touch but temperature and electrical fields. I would also include infrared thermometers. I would use no less that three layers for durability. Likely other types of material would be layered as well.
Muscles:
Numerous types of robotic muscles have been used, but the one described in the video seams best for smooth, natural movement without the need of water or high temperature. The muscles would be encased in nanotube skins as well to detect hard hits that penetrate the outer skin layers.
Base:
Well, why teach a robot to walk when it can roll. Everybody ends up in a wheelchair eventually anyway. If the frame's "legs" can flex and move, then it could even climb stairs.
Power:
An atomic power supply is not as dangerous as it sounds. It can last for decades and doesn't need to be charged or remain in sunlight to work. Additionally, each phone and tablet (or PC) will have it's own battery as a backup.
Hands:
I believe an opposable thumb on each side of the hand, would add to the abilities of a robot. While it would be somewhat cumbersome and awkward for a human to get used to, it would make no difference to a robot that never knew any other way.
