When people find out I build robots, the first question is “Do they fight each other?”

The second, almost always, is “Can you make me one that’ll get me a beer?”

This senior design project from the University of Central Florida uses an IR emitter (in the guy’s hand) and a mix of IR receivers and ultrasonic sensors to navigate the area around.  Reportedly, there’s also a water gun as protection against people blocking the path.  While undemonstrated in the video, you can spot the washer fluid reservoir they’re using for it.

What’s not to love?
