Baxter Bowling!

This summer, we had some great high school students work on projects involving our robots. Anisha Agarwal was one of those students. She built a bowling routine for Baxter. Here is here project!

With the ability to pick and place objects comes a surprising amount of power. Picking up objects and placing them down is the basis for setting a table, drawing, building block structures, playing numerous games and more. We decided to use this power to teach Baxter how to bowl. The bowling program sets up bowling pins and knocks them down by rolling a ball towards them. Baxter sets up 3 bowling pins from the home area into an area on the other end of the table. Baxter also picks up a “bowling” ball (although, for our purposes, a golf ball worked better), swings its arm and releases the ball towards the upright pins.

Occasionally, Baxter accidentally knocks down a pin in its attempt to place another one nearby. Also, a very specific gripper setting is necessary, such that the grippers are wide enough for the ball, but slim enough to grasp the thinnest portion of the bowling pins. Also, since all 3 pins and the bowling ball are presented to Baxter at once, it can be difficult to arrange them so they aren’t close enough together to confuse the robot, but also not so far apart that certain pieces are outside of the range where the arm can reach.

Despite these limitations, it’s exciting to watch Baxter setting up and knocking down pins!
