Design and Implementation of a Plantar Pressure Distribution Measuring System

Jing Li Mo Wang Xin’an Wang Zheng Xie Wulong Huang

In this study, we developed a plantar pressure distribution measuring system with 6720 piezoresistive pressure sensors array. The system consists of a pressure sensors array for sensing plantar pressure, a signal conditioning and data transmission circuit, a microcontroller with the ARM kernel for controlling the operation of the hardware circuit, a master computer for receiving the plantar pressure data, and a visual data processing program for displaying the graphics data of plantar pressure. This system is designed to measure the static and dynamic plantar pressure, and demonstrates plantar pressure distribution with contour maps. This paper describes the design method and the working principle of the system, and the good agreement between practical measurements and plantar pressure distribution of normal Chinese proves that the design method is reliable.

A Lower Extremity Exoskeleton System for Walking Assist

Zheng Xie Mingjiang Wang Wulong Huang Mo Wang Jing Li

In this paper, we proposed a lower extremity exoskeleton system for the elderly with poor walking ability. By way of supporting the weight, the burden of lower limbs was reduced. We designed a novel mechanical structure for high torque clutch to reduce the exoskeleton weight. Using non-binding manner, the wear convenience was improved. The system got gait details by the plantar pressure sensor. Combining gait analysis, the system control algorithm is based on force feedback control. The motor drive control used the current proportion integration differentiation (PID) feedback control. The prototype weighs 12.5kg. The support is about 10kg for standing and 3kg for walking.

A Weight-Supporting Wearable Robot for Walking Assist

Wulong Huang Xin’an Wang Zheng Xie Mo Wang Yucheng Tian

To realize an effective and universal walking assist robot, we developed a weight-supporting wearable Human-Machine system, namely exoskeleton. Based on human hinge model and human kinesiology analysis, we designed a novel mechanical structure with bodyweight supporting. Then, the sensor and actuator units were designed and optimized. Finally, we proposed the control method based on foot plantar pressure and crotch contact force. The prototype experiment results indicated it could relieve user's knee and ankle pressure, thus assisting walking. Mostly, the wearable robot will not inflict restriction on users and is suitable for different movements of people with different height and weight.
