Walking Assist Device with Stride Management System

Article of Honda R&D Technical Review Vol.21 No.2

Summary

This paper discusses a novel walking assist device that assists users in adopting a more efficient posture, muscular usage and walk ratio. An assist method was developed that coordinates the walk ratio of users while increasing their propulsive force. This assist method was implemented through a hardware system that consists of low-profile actuators and compact electrical components. The device is light and adaptable to users of various shape and size. A long-term experiment showed that elderly subjects using the walking assist device were eventually able to walk with a wider stride, at a higher speed, and with a lower heart rate, without help from the device. Their balance of muscular usage also changed accordingly. Energy consumption increased according to the increase in the subjects’ speed. This result suggests the possibility of using the walking assist device as a tool for increasing elderly peoples’ physical activity, while reducing the level of stress this would normally produce.
