Arduino autonomous tracked robot build Part 1

So I am finally taking time to write about this one. I created the monster some time ago but I haven't have the chance to talk about it. This is a simple (yet it took me a bloody long time to complete) Arduino Uno, motor shield, Ping sensor, infrared sensor, autonomous robot.
