Check the CAD but in rough numbers the pivot is about 1-1.5" behind the front of the robot and 0.5-0.75" below the top of the bumper (which is 7" from the ground).
They are not powered and we use acceleration to get the to fall (unless a ball is in the machine in which case we use the motors to "climb off" the ball). If I had to do it again, I would power this joint. I would drive it through a spring so that "down" would only bias the horns toward down and "up" would only bias them toward up. My reason for this is that we could cradle a ball as we drove so that it would be less likely to fall out during a battle for position. Also, we would have another (maybe better) way to remove a ball from the shooter and put it on the ground for another team to pick up.
I like this idea enough that i may do it just as a side project. Time will tell...
