Everyone loves a good game of bowling, but how exactly are the lanes kept nice and oily to maintain the perfect roll of the ball? A little robot called the Kegel Kustodian drives up and down each lane applying a thin coat of oil to the wood and also cleaning off any dirt left over from the previous use. Believe it or not, there are 8 different ways to officially apply oil to a boiling lane, and this robot can do them all. Check out the robot working in the video above.
