"Mini" 4-Claw Gripper Video
We designed a 4-claw gripper & fabricated it at 1:4 scale using a 3D printer. The test ball is a little large (7" instead of 6") but seems to work okay. http://youtu.be/FoE1ImP0pQI

Re: Vacuum Pickup
Thanks for all the great tips. We've found large diameter (=>10") vacuum cups online, but they seem to be for flat surfaces.
We have access to a 3D printer. In past years we've made molds with it &...

Re: Vacuum Pickup
Yeah, having our robot kick itself to death would be entertaining for the spectators, but won't help us win any matches.
A kicker might work. Or swing the ball up & drop it in a catapult.

Here's a quick test we did using a cut-down bucket left over from our 2013 Frisbee hopper: http://youtu.be/tPNvIXTAd4s

Re: Team Kickoff Meeting
Does anyone have an actual link showing the FIRST webcast times?
I've "heard" it's from 10:30-11:30, but I can't find anything confirming that on the FIRST web site.

Yup. But with some type of playing element to knock the bucket stack over. Maybe a bowling ball, like the 2012 FTC game?
