This project is developed for the users to control a Spray painting robot through Computer.

The main modules in this project is Personel computer, Computer Interface, Controlling circuit, Robot and painting device. The user can control all the operations of the robot using computer.

When the user presses a specific button of the computer, a digital signal is generated and sent through a particular pin of the parallel port. This signal is thus used to drive a corresponding relay in the external electronic circuit.

The relay is used as a switch to operate the particular motor in the device. By this way the user can control any of the operations of the device.

The robot can move forward, backward, left and right. It can spray paint like human being.

The design and port programs are written in Visual Basic. In future, this can be implemented by using embedded systems with artificial intelligence.

This device can be used to paint any vehicle in any place.

In future this can be implemented with artificial intelligence which can paint automatically
