WebIn developing legged robots the most important problems are the design of leg mechanism and the determination of how to drive it. We have already suggested the 'gravitationally decoupled actuation (GDA)' and 'coupled drive' for ground walking robot and wall climbing robot respectively. In this paper, we discuss about these problems for a legged robot in … WebGDA (Gravitationally Decoupled Actuation) and MDA (Motion Decoupled Actuation) are the most famous of the techniques. The GDA is a concept to avoid energy loss that is generated by interference of actuations (Hirose 1984). Then, the notion of the MDA is to make a purpose of actuation clear (Koyachi et al. 1991).
