You know when you were a kid and you used to play snake on your Nokia? At a certain point the snake would start chasing its own tail, and that’s when you knew the game was about to be over. We decided to make that into a robot, only, the game never ends, and the snake chases it’s own tail forever!

Here's how we did it:

Step 1: What You'll Need

2 IR Sensors
Arduino Uno
9V Battery
L298N Motor Driver
2 DC Motors

Step 2: Making the Circuit

This is how your circuit should be wired, it's easier to model it first on Fritzing before you start.

Step 3: The Code

The First file is the arduino code use to program the arduino uno

The second file is a sample of how your circuit should work.

Step 4: Assembly

The Assembly for this robot is very standard:

All the pieces are lasercut
The 2 DC motors are mounted by wooden dowels
Think of the IR sensors as the robot's eyes, they should be mounted at the front.

Attached is the AutoCAD file used for lasercutting the body parts.
