Abstract
Although legged locomotive robots are expected to be widely applicable to various environments, most legged robots have poor continuously dynamical movement since they do not have a spring element in their leg that corresponds to animal tendons. Thus, we developed a one-legged hopping robot explicitly with a spring element and investigated the relation of mechatronic elements to the generated motion. Through our experimental results, we show that critical timing in motor actuation during jumping and landing greatly but complicatedly influences the robot's hopping height.
