I also think the clock on the robot was genius as drivers can't afford to look away from the robot.
Time is definitely on my mind. El Toro is reliable and (imho) robust but it is not the fastest way to pick up a ball.

Current configuration has a 20:1 ratio from Banebot 775 motor to the horn. I think that perhaps a lower ratio (i.e. faster spinning) would make El Toro better.

As to pushing the ball away, the angle of the horns did a pretty good job of trapping the ball. Again, El Toro is not the perfect ball pick up but it is pretty good.

Dr. Joe.

P.S. Display on the robot, I really hope that a bunch of teams implement these. It is SO useful. I expect a lot of creative uses to come from the teams this year and in coming years.
