task of this project was to program the AVR microcontroller interfaced to a radio packet controller module (operating at a frequency of 433 MHz) which would enable us to wirelessly control the Robot. The communication protocols dealing with transmission and reception of data and wireless control of the TekBot have been successfully implemented. These details are discussed in this report.
