Abstract
Toward elderly society, development of machines for assisting human walk is getting more important nowadays. Some assisting machines of a cart type have been developed. However, it has not been clarified how the machines effect the generated muscle tensions and energy consumption of human users. In this paper, we have evaluated a human walk using the cart which was developed for this research. We estimated the energy consumption based on the muscle-skeleton model. It is shown that the energy consumption using the cart has decreased by 15% of the normal gait. Our evaluation method will be useful for developing practical assisting machines.
