I'm curios about robotic locomotion. I see some are pneumatic powered, some use regular servo motors, and some are in development to use that new Artificial Muscle polymer.
What else can they be powered by?
I did some reading on electrostatic motors. They're super compact, but not very powerful.
I also see that there are torque motors, but those are heavy.
What would be small, efficient and yield a large amount of torque? I guess speed is not important since you're only moving a limb/lever a short distance.
