What's the same in robotics legs and human legs and what's the different?

Answer 1

The similarities would be the application of the leg. but that's where they end. Robotic leg use pistons that push the rods they are attached to, human legs use muscles which pull on the bones to move them. Robotics involve a heavy amount of electricity, humans use very little. (Most in higher brain functions, still less then an volt) without going into alarming detail the last thing is robotics are far more powerful and easier to repair, although much more expensive.
