How exactly does the crane mechanism on juggy work? how reliable is grabbing big balls and holding on to them? Is the pick up and delivery fast? Any answers would be greatly appreciated.

The boom is telescoping aluminum driven by a seat motor with rack & pinion, the gripper is incredibly strong and driven by a Globe motor (I was amazed when I first saw it: Ed Croswell,the head engineer at 3Dimensional Services, always manages to come up with some simple yet elegant solutions each year); the Globe has gears that mesh directly to teeth cut into the metal plate that the jaws mount to; the boom has a lead srew-driven lift that is painfully slow, but fortunately can be raised by the time we get over the bridge, so picking up balls is actually pretty quick: the winch is geared for speed (I've seen them pick up two large balls and score them onto goals that are already up on the bridge in @20 seconds from the time they cross the bridge). Is it reliable? We drove for 2 weeks in practice with pretty high reliability but at Western Michigan there was a series of nagging problems that seem to be corrected now: we'll see tomorrow!

You guys sound like one of the only teams out there that can put a big ball on top of the far balanced goal across the fence on the end zone side. Gompei 2k1(team 190) can also achieve this feat. If you guys get the chance this weekend in comp to put it on the far side, and can remember, take a pic and put it up, I'd love to see it.
