When the power is given to the circuit the controller will on the DC motors, which is connected to the fork lift wheel. So the fork lift will move in forward direction on the black line. When the right side sensor sense the black line means the controller will rotate the wheels in right side. When the left side sensor sense the black line means the controller will rotate the wheels in left side, so that the robot can follow the black line.
Our model consists of three motors. The first two motors are used to run the robot model. The third motor is in the front of the frame which is mounted with the lead screw arrangement. The fork lift arrangement is mounted on the lead screw such that it can be moved up and down. The third motor in model is used for up and down movement of the fork. The above all arrangements are used to lift a weight from one place and carry it to another place. The whole setup is operated through remote signaling device.

1.3 Target Users
The Automatic Forklift System (AFS) is designed to make the process of stocking efficient while decreasing unnecessary work related spending. A one-sixth scale model forklift is being used to demonstrate the feasibility of the project. An operator will control the system at a safe distance away from the forklift, such as in a separate control room, decreasing the risk of work related injuries with a handheld user interface.
The intended users of the AFS would be distributing
