1251 used the big cim and small cim in a combiner 2 speed gearbox. The design was a bit over thought but pretty good for a first time custom two speed it pushed almost everything. I have some pics if you would like to see just pm me. Currently, working on the same motors in the KOP as last year we are designing a three motor 2 speed ball drive. This would use two small cims and one big cim per side. :rolleyes: Were working on improvements for next year so all kinds of ideas are being thrown around.

in 2005 we had 4 small CIMs, two 6 volt fisher prices running at a full 12v and two speed shift on the fly transmissions. In 2006, we used 4 small CIMs and very small two speed shift on the fly transmissions.

#6

4 small CIM’s two per KOP gearbox.

#7

Four small CIMs, divvied between two KOP gearboxes. Never a misstep from 'em the whole time.

#8

Same here.

#9

We used 4 small CIMs on the KOP Gearbox last year and 2 small CIMs on the KOP Gearbox this year.

#10

We also used 4 small CIMs on the KOP Gearbox this year

#11

We also used four small CIMs on the KOP Gearboxs

#12

We used 4 small cims in the KOP gearboxes, like the last five people or so. Next year, I hope we can get a couple cool multi-speed transmissions put together… eyes 716…

#13

We used 2 small + 2 big cim motors in the AM 2 speed. Worked beautifully, and we’re hoping to make a 2 speed we designed.

#14

4 small cims in dewalt trannys

#15

2 small cims in 2 KOP trannies <- bad idea, too slow, too weak, saved weight though!

For next year, 4 small cims between 2 custom made 2 speed transmissions that we’re currently designing.

#16

4 small CIMs with a custom speed reducer for each, driving custom omniwheels like this and this. A fun summer 2005 project for learning about holonomic drive, but not an effective propulsion scheme for Aim High. :o

Like most other holonomic robots we were very maneuverable, but too easily pushed off-target. Here is a shot of our robot in action against a good opponent.

#17

4 small CIM’s. Two per custom made fully closed off HDPE Gear Boxes. (the box was HDPE, not the gears).

#18

4 small CIMs in KOP gearbox, 5.7 ft/s. Worked quite nicely. Next year, maybe either 4 Sm. CIM in DeWalts, or 4 Sm. CIM in a 33 style four speed. (Although I’d really like to do 4 Sm. CIM + 2 FP in AM planetaries + 33 style four speed --> unrealistic)

#19

4 small CIMs, 2 per in our dual speed gearbox. Same design as 2005 so no new white paper this year.

#20

We had pneumatic dog shifting (shifton the fly) tranmission with completely custom designed and manufactured gearboxes. We used 4 CIM’s and 2 FPs.

#21

Cyber Blue used the traditional 4 small cims
We were cool and shifted with servo motors :smiley: (They don’t like to shift on the fly very well though…)

#22

We used 4 small CIMs on DeWalt transmissions, in a holonomic configuration. It was a bit of overkill, as we never really utilized the shifting feature. It was cool to say we had a shifting omni-drive robot, though, even if we didn’t use it :stuck_out_tongue:

#23

team 340 had two small cims with two speed andy marks
