Didn't you ever wanted to have a robot servant? Serving around sandwiches and cookies at your cool parties? Yes, I know you did. And here he is! Sebastian 3000, your immortal non sleeping servant that will cheer up every party you throw, or will kill you in your sleep with his ultimate mustache of destruction if you forget turning it off.
Anyway, Sebastian 3000 is a sanguino powered robot, with 2 hardcore tank treads driven by 2 gigantic gearmotor (a lovely set from solarbotics). he has 2 servo in his neck in order to let him look almost any angle he need. He can create maps of his vision by scanning the environment angle by angle with its infrared rangefinder. Plus he is using an awesome high speed obstacle avoidance algorithm in order to find his way in a complex party environment with many moving obstacle (we call them humans).
