Mechanical antagonism in legged robots
WebThe legs of a humanoid robot are generally designed with attention to the following points: In order to realize (1), each link is designed to have high stiffness against bending and torsion, and a mechanism with small … WebAug 9, 2024 · A fundamental difference between locomotion mechanisms is whether they are statically or dynamically stable. A statically stable mechanism will not fall even when all of its joints freeze (Figure 2.2.1, left). A dynamically stable robot instead requires constant motion to prevent it from falling.
