Moving Beerpong Robots: Challenge Accepted

The BRUU Moving Beerpong Robot is a small, wheeled robot designed to hold six 16-oz Solo cups on top and randomly move around the table while you play beerpong, adding an increased level of difficulty to the game. Thankfully, it’s outfitted with sensors so it doesn’t fall off the table and constantly waste beer. Available on Amazon as single robots, it gets about 20 hours of game time on a single charge. Not bad, but we’ve been doing this with Roombas for a while now. And by “for a while now” I mean starting this coming weekend.

Keep going for a video of some guys playing kiddy pong on a ridiculously tiny table, basically just dropping the balls into the cups.
