The purpose of this thesis is to balance a mobile suspension platform by using an ARM-based embedded system. The suspension platform is comprised of mercury switches, two-axis accelerometers, and DC motors to implement the balance control. And there is an omni-directional mobile robot which is linked below this platform. The omni-directional mobile robot was used field-programmable gate array (FPGA) technology to achieve the control of three omni-directional wheels by three DC motors. The signal of control output is from the Wii Remote. It can control the direction and speed of the mobile robot. This suspension platform is executed by fuzzy control theory. This platform uses the closed-loop signals to control the speeds of DC motors. In addition, in order to lift up goods there is a compensation mechanism for output strength. With the characteristic of mobility and balance control, the platform can be applied to delivery goods smoothly without rollover when it is moving on the road with ups and downs.
