Summer VEX Projects?

[gdo]

Team Unlimited (FVC 2013) designed and used a gear shifter in their competiton robot. We recently made a model of the shifter in Maya 8, and some pics are posted (or being posted) currently here in CD-Media. At the current time only this:

Photo is posted. More are being posted and should be up soon. Our team is posting some information on the shifter at our site:
http://eaglevex.syraweb.org
The information should be up in a day or two hopefully. There are some pictures of the prototype design are in the photo gallery on our site under summer projects.

UPDATE:
We got the information posted on our shifter.

It can be found here: http://eaglevex.syraweb.org/GearShifter.htm

Some prototype designs can be seen here: http://eaglevex.syraweb.org/MiscSummer2006.htm

And the robot can be found:

For the shafter encoder, it is placed on the "block gear" (three wide gear) and it worked very well in autonomous. Hope our post on our site helps with any question, if you have any more question, you can PM, AIM or MSN me.

Update: I've dropped the motorized cart idea in hopes to build a very small robot... possibly only 5 inches long by 4 inches wide in hopes that I can smuggle it into work and show it off behind my boss's back.

I know that a couple of the guys on my team are thinking about making a submarine vex bot...but it will be a pretty big project considering all the sealing that they will have to do, just to keep the water out.

Going for the classic ping-pong ball shooting robot... but the catch is, I'm trying to do it with as little extra parts from the starter kit as possible (1 tread kit, 1 chain kit, 1 metal kit, 1 gear kit, and 1 or 2 motors, but that's it).

As I speak I am printing some Vex Mecanums on a Rapid Prototyping Machine. So I am probably going to make a Mecanum drive with full suspension. Also I bought this awsome mini Poofball and I am going to try to shoot it about ~25ft. I'll probably try some PID loops too.

I'm currently making a 2-speed robot to play this year's FRC game with the full-sized tubes to score on the low part of the rack. The cool thing is, I can dismout the tube manipulator and attach a (student-made and not currently used) claw for the FVC game that can score 4 balls at a time for some added fun with the current FVC students.

I'm also considering dropping the 2-speed drive train in favor of an 8-wheel 4-motor omni drive so I can come up with some control algorithms to be used on a future FRC bot.

we're planing on developing a couple new drive trains. probably a holomonic, 6 wheel drive, and we may try to do a 2 speed transmission also

My team is contemplating doing several projects, any teams that were at the world championships will remember the cockroach that was showcased by DARPA and we're going to try to replicate that out of vex parts. We're also thinking of making a 4 speed transmission. It would probably take up much more space than would be usable in a competition robot, it would more be a proof of concept. We're also in the process of coming up with several challenges to train new members on.

Last weekend, we had a joint build session with team 3613, TBA (Tee-ba), who graciously agreed to drive 2 hours (each way) with the promise of free food. The outcome was 2 major projects:

1) A candy counter, which sorts black & white chips onto opposite sides (black and nothing tilt the sorter on the same side). The original intention was to count the objects in each cup with a limit sensor, but we ran out of time. We also would have liked to add a second sensor so that two whites in a row don't require the sorter to reset each time. The line tracker sensor worked better than the light sensor. You can see the action at:

2) A dual differential drive, which was not completely functioning by day's end.

Unfortunately, the projects required the kits of both teams with borrowing of parts back and forth, so they had to be disassembled at the end of the day However, I thought it was a rather productive effort for one afternoon.
