Another idea that I wanted to try to make work with Cozmo was to build a claw that would open and close as Cozmo raised and lowered his lift – it worked a little, but not quite as much as I hoped (the motor that raised and lowered the lift wasn’t very strong!)
In user testing, I learned that the lightweight ping pong balls would roll far away when thrown, or be a little difficult to pick up since they would roll away easily when bumped – I made some prototypes of balls with dimples or holes ot keep them from rolling away.
An issue I ran into was that the balls would be more difficult to “throw” since the pits or holes on the ball would sometimes line up with the flicking arm on the prototype I built.
