This is a picture of our newest robot. We had a lot of free time recently, and felt we should build a chassis that has a new and improved gear shifter (better and before than the year before!).
Team Unlimited would like to wish the best of luck to all FIRST teams for the coming competition season!
For information on last years competition chassis / gear shifter, feel free to check it out at: http://eaglevex.syraweb.org/GearShifter.htm.
Regards,
~ FTC 1, Team Unlimited
P.S. If you have any questions, feel free to contact the team through the site, or email me, PM me, AIM me, or MSN Messenger me. BEST OF LUCK TO EVERYONE!

What sensors are you using in the back of your robot?

I think it would be best to use a real servo with a limited rotation and exact position for shifting the gear, instead of a motor...
all in all amazing design! very cool!
I really like how it shows the complex notion of gear changing in an easy to understand way...

How did you guys get those three gears in the back flush against each other (cut off protruding edge or just different gears?)

Re: pic: Team Unlimited's Gear Shifter

There design is shift on the fly but the can shift stationary. The rack and pinion make much it smoother. I dont know if you can see it or not they also beveled the gears with a drill and sandpaper.
