摘要: Most of low-cost and small-size humanoid robots have been developed by using the conventional mechanism simple control units. The has a unique structure when pose feet waist is fixed, small robot to walk with bending knee joints without joints. On other hand, these perform low capability in dynamic walking because open-loop hardware computation performance. In order improve problems, biped 7 DOFs double spherical hip joint this paper. There are two primary advantages compared those robots. First, new can realize motions which more similar human beings. Secondly, foot-force sensory system designed make close-loop, quick response stability proposed control. effectiveness our was confirmed experiments on an actual 14 mechanism.
