Force-Shoes ZMP Measuring System for Human Walker

A novel force-shoes system for measuring the Zero Moment Point (ZMP) of human walker is introduced in this paper, which could measure the plantar distributed normal forces and friction forces during human walking. The improved ZMP calculation method developed in this paper is easy for programming. In contrast with the previous ZMP measuring methods, there are many advantages of the proposed force-shoes system, e.g., light and novel structured, low coupling, easy for programming, less affection on normal walking, suited for long-time and diverse terrains testing. Two experiments carried out on different terrains, one is on the plain and the other is on the slope, are presented in this paper and some of the results are shown and discussed.
