This project is intended to control the robot path using PC. The control unit in receiver section controls the robot direction according to the commands given from PC which is send through the transmitter section by means of RF wireless communication. 8051 micro controller is used as control unit. There are two sections in micro controller. One is transmitter and the second one is receiver section. Transmitter section consists of PC, micro controller and RF transmitter. Micro controller is interfaced with PC through serial communication using UART TTL converter. Different directions of the robot are controlled through instructions to the robot with the help of data given to the PC using keypad. Data will be given to micro controller and controller will transmit that data to receiver module by using RF transmitter.
