Actually, we've tried this.
Our first get-together was an all-day event, where we did all sort of messing
around. In addition to a ton of soccer balls, I've receintly picked up a few
different basket ball sets, including a set that had two blue and two red
basketballs. So, I have about seven or eight different types.
John used a light sensor to detect balls in his backhoe, and he discovered sometimes
the black spot on the soccer balls ends up in front of the sensor. So, if his robot
sits for a short time, without seeing any balls, it will "stir" the balls (scoop,
but not pick any up).
I do have video of us tracking a blue ball through the contraption. It seemed like
it just missed every scoop, lift and everything else. The ball took about three
minutes to make one "lap".
