Since Pittsburgh is only a couple days away, I figured I would post what video footage we have. For your enjoyment http://www.youtube.com/watch?v=yLuLzc1rGmw:cool:
Specs.:
Drivetrain: 6 wheel drive, 4 CIM two speed Tigerdrive ball lock transmissions, 4 plaction wheels, 2 dualie plastic omni wheels and raised center wheels to help us over the bump.
Multiple position kicker: Kicker has three programmed positions, but can be stopped at any point between those three positions. Surgical tubing provides the kick and window motors and a gate latch provide the preload. We have an automatic aim mode and a manual aim mode with feed back that is displayed on our dashboard. Also we have a kick strength meter displayed on our dashboard
Ball magnet: Our ball magnet is comprised of two small rollers that pinch the ball. The video is of our rough design that has since been improved to ensure a tight grip on the ball.
Hanging/righting arm: Our arm uses fisher price motors and p-60 Banebots gearboxes for rotation and extension/retraction of the arm. After we are hooked on the bar we retract our hook to a latched position and use our shoulder rotate us fully into scoring position.
The video isn't of a finished machine, but that's all the video we have. We should have a much improved ball magnet for Pittsburgh after a couple tweaks.:)

AWESOME! I personally can't wait for Pittsburgh because it is a smaller regional. In my 7 years of robotics, I personally have never been to a regional with much less than 60 teams. It should be interesting.
If you will entertain a few questions/comments:
1. I am worried about your hook hitting the ball return since the actual hook part is so tall. Can you comment on this?
2. Your undercarriage is low. How well does it traverse the bump? Do you get almost vertical?
3. You have nice distance on your kicks. Do you have an autonomous period to utilize them?
4. I hear your compressor turn on after you kick. What is pneumatically operated?
5. FYI- Our team had an auto aim with the camera. But from a distance, because of lighting, or small adjustments in angle, or just generally how visually busy the arena was, our camera had a tough time aiming exactly at the target. In fact we shot a ball at a ref one match. If you get this to work, we might be interested in checking it out. Would that be alright?
In general, awesome job guys. I would love to come get to know you guys on Friday or Saturday. I will be sure to stop by. Good Luck.

Wow that was quick...:)
1. I forgot to mention that the hook has been trimmed. It's now a nice small hook that won't touch the ball shoot or cause us to extend above 90".
2. We traverse the bump similar to the 8 wheel non-suspended robots teams have posted video of. We raised the center wheel to help with the transition rather than just running a flat 6wd setup.
3. Thanks! We have untested autonomous modes that we will hopefully tune in during the practice rounds. At a minimum we hope to be able to at least clear the zones we are in and hopefully sink a couple shots in the goal.
4. We use a cylinder to unlatch our gate latch which releases our kicker.
5. Thanks for a heads-up. We don't have a large testing area and we didn't have a whole lot of testing time with the aiming on this robot, but using our 2009 robot as a test base we were tracking the target from across the classroom. I will be sure to talk to our programmers and relay your experiences.
Definitely be sure to stop by our pits and check us out.
Pittsburgh is a great regional. The atmosphere and interaction between the teams has made it our favorite regional. I hope your team will enjoy it!

Cliff, the Robot Looks Awesome! One question though, can it go through the tunnel? I guess you can retract the hanging mechanism to do so?
I hope to see it in person somewhere.

It was built to go under the tunnel, but that was scrapped during the last week of build to due several reasons. Camera mounting and conflicts with the lifting latch we added. We determined that it was just going to be too difficult to squeeze through them anyways especially the farthest one from the driver station.

Awesome robot, how far can you kick a ball?

All the way! ;)
Sweet robot,
You say window motors, How many?
Thanks,

Congratulations on a fantastic robot. How well does the ball magnet work when the robot is in motion?

It should work quite well once the team makes a few changes at Pittsburgh this week. Unfortunately we really struggled with the ball magnet the last week of build, but we think we have will work great once we get it tuned in!

We use two window motors to load the kicker. Calculations said 1 window motor was right on the verge of being able to do the job, but we decided to go for 2 motors just in case.

Way to go Cliff and co.
The hanger looks pretty sweet, and the kicker looks like its got some serious pop.
Assuming that ball magnet is tweaked I think you guys will once again have a formidable machine out there. I'll be watching in Pitt assuming its webcast.
