It is remote controlled via bluetooth laptop, cellphone, or PSP. So... what does it do? Besides being remote controlled, it can act autonomously. It has an ultrasound sensor (think of sonar out of water (think of radar...)) at the top to see what's out there. It can look around and find an energy drink. Then it will move towards it, grab it, and move it away. It can also pour you a drink if the can is opened. Well I like it... Any feedback would be awesome...

When it is acting autonomously, does it move around looking for the can or does it stay in one spot and scan for it within its ultrasound range? If it does move around, does it have a systematic search pattern?

I made it so it spins around in a circle to find the closest object, presumably an energy drink, and moves towards it, tracking it as its goes in case it goes off course. When it gets within 10 inches of the object it checks the width of it. If it is under 3 inches wide the robot will try to pick it up. If not, the robot turns around to find another close object. And then it does the same thing... I have looked at a few programs for creating a map of the area with a single sweep of the ultrasound. I understand how they work, and can have the robot save the map to a file, but getting it to do something with that data has proved challenging.
