Create a safe-driving robot aware of it's surroundings

[hopkira]

Enhance the existing robot with the ability to sense its environment and make automated changes to its direction and speed based on input from sensors. This should include the ability to stop and make minor corrections to avoid obstacles. It should also include the ability to stop the robot from entering into dangerous maneuvers. This includes spinning or turning at high speed, spinning when not enough room or reversing at high speed.
