This project consists of designing, building, and operating a robotic device which will move in its environment by its own power. The hardware section consists of computer circuitry using an eight-bit microprocessor as the "brains" of the system. Also included in the hardware section are the sonar guidance and motor control systems. The robotic system uses a twelve volt motorcycle battery as its on board power supply which allows the robot to move about in its environment for around four hours. The software section consists of sub-routines which interface the computer circuitry hardware with the two control systems. The sonar guidance subroutine determines the placement of obstacles in the robot's environment and the computer circuitry controls the wheel movement accordingly. Integration of these two sections results in the creation of the robotic system.
