碩士 === 國立臺灣大學 === 機械工程學研究所 === 92 === The purpose of this thesis is to develop a new design of the new walker which can provide better support and stability for the severely disabled. And the new walker must include the speed control and the device to prevent the user from falling down. First, the mathematical dynamic model for the new walker is constructed. This model analyzes how the dimension of the walker influences the braking performance. Besides, the rear wheel of the walker is equipped with the electro- magnetic brake (EM brake) which can be triggered by the controller and therefore lock the rear wheel when the speed of the walker is too high. Furthermore, for the sake of the user’s safety, the damping device in the rear wheel can provide appropriate force to prevent the walker from slipping too fast. However, the controller and the EM brake have to work with sufficient supply power. As a result, the controller must be able to provide a good estimation for residual capacity of batteries to avoid possible dangers resulting from the insufficient power supply.
