As tools to assist elderly, crutches facilitate the life of the elderly to a large extent. But most of the crutches on the market have limited functions. In this article, a new type of crutch with multiple functions has been designed. This crutch has the function of picking up, locating and lighting. Firstly, the function of clamping is to drive the tightening and relaxation of clamp through the rotating output displacement of type 42 stepper motor, so as to realize the picking up of objects. Additionally, the positioning function is realized by ultra wide band(UWB) technology. The UWB technology provides the support to help locate the crutch’s position precisely. Lastly, the lighting function uses LED, which shares the same battery with the stepper motor. According to researches and experiments, those functions presented above have been achieved. And this crutch provides a direction for future products to help the old people.
