As the inspection tour targeted at disarranged parking phenomenon conducted by specially assigned security personnel to parking lots in neighborhoods makes it more difficult for parking management, this paper proposes an FPGA-based character recognition robot design. The camera was controlled by the master controller EP4CE115F29C7N to acquire the license plate information, the improved character recognition algorithm based on YCbCr color space was put forward to identify the license plates, and the robot walking was controlled by combining IR control with increment-type PID. The experimental results show that this robot is of certain practical value as it is capable of effective recognition and displaying the characters on the license plates.
