Abstract
We present the design of a simple and low- cost humanoid leg-foot system featuring compliant joints and springy feet. The mechanical compliance of the individual joints can be adjusted by means of visco-elastic material, or metal. To explore some of the relevant characteristics of the proposed system, we performed a series of experiments in which the leg was dropped from a fixed height. Combinations of different materials in the joints (silicone rubber, latex, and brass) as well as a rigid or a compliant foot were used. Additional data were obtained through of a Lagrangian analysis of the leg-foot system. Our analyses show that compliant joints not only reduce impactive forces, but also induce smoother joint trajectories. Further, by employing a compliant foot, a higher energy efficiency for the movement is achieved.
