as per the question at hand...soccer it to me.

an answer to my question...it's a lot harder than i think most people were thinking it would be to herd balls. they have to be rolled quite slowly and with about zero bounce to go in the chute...good luck to all the ball herders!

Yeah, It's not an easy task to get the ball into the corrals. They short, narrow and the aren't very deep. Any bounce misalignment or too much speed can throw your chance of sucessfully keeping it in the goal off. The two best ways I've seen to have maximum control of the balls is either gather them in a hopper of sorts and release them straight into the goal or use some type of pool stick device. I'm very interested in the second way but haven't found a successful way to make this happen. It relies on more speed than the cyclinder can give and I haven't figured a good mechanical way to do this yet. If anyone is using this way to so call kick the ball into the corral I would be interested in how. One of the most interesting ideas I've thought of is a octagonal crab drive robot in which each side plate pops out 4-6 inches. I would call it the puffer fish bot. The ultimate ball controller. Maximum mobility and barring no obstruction it could make shots from the opposite corral. And it could make 45 degree angled shots to. Oh I would so have loved this robot.
