Boomer is a new tennis robot that vastly improves on the current tennis ball machines. Instead of just firing balls randomly at its opponent, Boomer has the ability to serve, return, play out a point, call the lines and the score, rate the quality of shots, and even "talk trash." Using a computer and a camera setup, Boomer tracks the location of the tennis ball in the court. If the human opponent makes a shot that's in, boomer will reply with a "realistic" return. This continues until the human or robot makes a mistake, or when the human attacks the robot for its nonstop insults. Boomer's skill level can be changed from beginner to world champion, and it costs approximately $14,450. If you can't find an actual person to play tennis for $14,450, I suggest you take up a less social sport like solitaire or vandalism.
