Operating Radio-Controlled Cars by a Computer

The objective of this research is to operate a radio controlled car by using a computer (ORCCC). The remote controller of a radio-controlled car or RC car is connected to a computer via a parallel port. The ORCCC converted a digital signal to a radio signal and then sent the radio signal to communicate with an RC car. The research was conducted on three types of operations, namely: 1) computer commands to operate an RC car by sending computer commands directly via a parallel port, 2) Thai voice commands to manage an RC car by applying a voice recognition technique, and 3) facial commands to control an RC-car by using an image processing technique. The experimental precisions are 100, 96.6 and 84.11 percent for the computer commands, the voice commands, and the facial commands, respectively.
