Abstract
Recently, the personal mobility have been developed to reduce an environmental impact as a measure against global warming. Electric power assist bicycles are the most used for cheapest price under the classi cation of the personal mobility. Segway and the other personal mobilities have high performance functions such as self standing control. Electric power assist bicycles have only one function such as assistance of driving forth with torque sensor and speed sensor. On the other hand, the bicycle parking lot is short in highly populated urban areas. Therefore, the purpose of this research is to develop a standing personal mobility " Oteller" for increasing space efficiency of bicycle parking lot by miniaturizing a body using a driving wheel. Oteller treads at three point using two assistant wheels to suppress the instability of the body without the sensors for self standing control. Turning is performed with moving weight balance. In this paper, it explains about the design of Oteller and the run experiment using a prototype.
