Deep Green - A Pool Playing Robot?

o0zi writes "A Canadian scientist has created another game-playing machine, designed for a far simpler purpose than chess: playing pool. The world's first pool-playing robot consists of a slim box that glides along tracks above a pool table, and shoots using a camera-guided cue. Deep Green pots only half the shots it plans for - supposedly the same as a below average player - but this is expected to improve."
