What are you building?

A simple remote controlled robot that can be controlled using an IR remote that is used for a TV or DVD player, or an equivalent IR remote.

Benefits:

The basic working principle of this remote controlled robot is that the signal sent by the IR remote on pressing Play/Record button on the remote is saved in EEPROM of the microcontroller (MCU) in record mode. It plays back the same code (signal) when you press the same button in play mode. The program for the MCU can save 4-bit code (0 to F hex code) in record mode and output the same 4-bit code when the button is pressed in play mode.

Using the combination of these four bits, two motors installed on either side of the robot (third one being the caster wheel) can be controlled through a motor driver IC. Thus, different codes are used to control different movements of the robot.

Parts list:

ATmega8A microcontroller, L293D motor driver & 2-DC motors, IR Receiver module TSOP1738, 5mm LEDs etc.
