- Remote Control Car
- Small circuit (IR LED, IR Phototransistor, Relay)
- 3 Batteries for power
This was my first robot ever. (if you can call it that) Yes, it looks like a wreck. It looks like I literally ripped apart the car ($5.00) from Radio Shack and then put it together with duct tape.
I wanted to add a sensor to the robot so I created a primitive IR detection system that operates at about 5 inches. Because it is not modulated it is affected by strong light sources. This system consist of a IR LED and an IR photo transistor. I connected the two to a relay that either turned on the power or off the power to the motors.
