An efficient car like-mobile robot design

This paper presents the hardware design and implementation of a car-like mobile robot that work in an efficient way. The robot is programmed to avoid colliding with obstacles in its way by the aid of ultrasonic sensors. It will change its path if the connected sensors detect an obstacle. After passing the obstacle, the robot will continue on its original path. The system was designed using VHDL in a high level design method. All parts of the design have been simulated and implemented using Xilinx tools. The system was tested in both simulation level using ModelSim and hardware level using Xilinx Spartan 3 AN development board.
