| Summary: | 碩士 === 國立交通大學 === 電機學院電機與控制學程 === 106 === The massive usage of robots is a trend, from mechanical arms for repeating tasks to various intelligent robots making judgment of next movement. To make a robot to work, energy supply is a crucial key to the robotic system. Not every robot can work in an environment with sufficient energy supply, therefore they must be provided with an independent electrical power supply, e.g. robots used in farming or exploration, or those working in transportation. There are many kinds of sources that can be used as energy supply for a mobile robot. For green energy, fuel cell is one of the most suitable power generation devices for robots. It almost has no pollution to the natural environment. Fuel cell is a device turning chemical energy to electricity, very efficient for resupply energy. Traditional rechargeable batteries are limited with location and time consuming compared to fuel cells. This thesis develop a robot of fuel cell power supply system, with consideration of charging factors to compatible design, which makes the integration of each characteristics of green energy and storage system. A power supply system is proposed to combine the high endurance of fuel cell and high current output of LI-polymer battery. Practical experiments verified the effectiveness of the proposed design using a walking-aid robot in the lab. It is hoped to develop a fuel cell power supply system for robot to help not only the robot applications, but also for emironmetal protection in the future.
