Development and evaluation of an electric walking machine

As society ages, the exercise of elderly people has become increasingly important. Therefore, this study was conducted to complete an electric support cart that can encourage elderly people to exercise. For this study, we produced a prototype of an electric support cart and evaluated it. The prototype was designed so that the user can walk in a natural walking posture. We used a VICON motion analysis device for measurements. We measured the state of walking using the prototype and compared it with normal walking. Measurement results confirmed that each joint moment of the lower limb was greatly reduced. The prototype produced in this research is effective for reducing the power necessary for walking.
