The competition!

The main website for the competition is described here:
http://ratslife.org/

Basically the competition takes place both in a simulated virtual environment as well as a real one (though the real case is too slow so for actual rankings they just use the simulated). Real case uses lego.

Robots are placed in to a maze (random) in pairs- whoever survives longest wins. Robots have a simulated 'power meter' which they must replenish at power sources scattered around the maze. Once you replenish the source deactivates for a set amount of time before it can be used again (so you can go look for a new one in the mean time).

Each robot is equiped with
-8 Distance Sensors
-10 LED lights (just for fun?)
-1 Camera
-2 Wheels + Accelerometer
Each

Sounds like fun.
