Summary
Main idea
Robots can be stiff and rigid, but that is not the only option that one has when creating a robot. In order to make robots move more human-like, a mechanism is introduced where actuators with "adaptive compliance" are created tested:
- “Nowadays, more and more research groups working on bipeds have started to believe that natural biped walking is a combination of both approaches, requiring actuators with adaptable compliance (inverse of stiffness), resulting in energy efficient walking at different speeds.”
- “Human joints are actuated by at least two muscle groups, giving them the possibility to change the stiffness of a joint and to control the equilibrium position. By controlling both the compliance and the equilibrium positions, a variety of natural motions is possible, requiring a minimal energy input to the system.”
