This intelligent robot uses simple ruleset behaviours to exhibit advanced characteristics. 

In other words, it reverses then rotates when near a wall before moving forward again. This allows the robot to appear to be exploring the environment. It is powers by two servo motors on either side at the rear.

KNOWN PROBLEM: The servo motors draw a large amount of current, yet I am still to find a light enough battery with a high enough current to provide the motors with sufficient power as to maximise rotation efficiency. I imagine a 9 Volt battery would work, although I do not have one at hand.
