This was my second Robot that I built after I started making robots. Very basic r/c car which does not use any micro. Its based on a 8 bit encoder/ decoder and a pair of RF Transmitter/ receiver. with some custom made High current H bridge motor driving circuits.
I bought some toys which served me the wheels, motors and the gears, The black portion around the wheel was completely extracted from a cheap plastic toy tank. The circuits were made on a ptoto board and was enclosed within a chocolate plastic box(with chess board on the lid :P).
I used four channels of the available eight channels from the encoder/decoder for controlling the direction of the robot. The motion is differential drive mechanism (remember I used parts from the toy tank) Of the four unused channels, I used one channel to turn ON/OFF the white LEDs which serve as head lights for the car ;)
This Bot is dead now with the cheap parts of the toy tank broken into pieces. I have the details of building this robot in my website, I will share the link below if someone is interested in implementing it .
