Recycle bot 5000

This robot is one of my robot entries. i will probably make another one. So like i said this is my robot entry for Chickenparmi's Scrap bin challenge.This robot is an obstacle avoidance robot.When it sees something close it will stop then turn left and then continue moving forward.It was a siple code to do.

For brains he has an Arduino uno r3, 2 geared motors to move, 2 9v batteries one to power the motors and the other to power the arduino, for his eyes or sensors i put a HC-SR04 ultrasonic distance sensor, the backwheel is actually just a bottle lid. His body is all made out of cardboard and the wheels are made of styrofoam. On the robot chassis you will see a cardboard box and in that custom made cardboard box there lays his brains (Arduino) and all the wiring.
