Most likely. I suppose for lower-load applications you could make 10-32 dead axle gearboxes, axles, etc.?

As well as high load applications.

A good COTS brake solution. Perhaps one from VEX that would interface with their versaplanetary system. This would have saved our team a lot of time and resources this past season.

You know... Y'all are learning engineering. I'm aware that AM at least will take design ideas from teams (they've done it in the past).

So... You want something to be a COTS offering, how about you make a prototype, do a bit of market research, and see about making a deal with the appropriate company?

Just a thought.


One final item: [geezer]Back in my day, we didn't have these newfangled 3-CIM gearboxes! All we had was drill motors, with drill gearboxes! Had ta make 'em shifting ourselves! COTS parts? HA! Had to build the entire robot, 'cept the KOP! More than 2 CIMS? HA! We was lucky to get that! You young whippersnappers have everything handed to you! Ya wouldn't last 2 days if you had to build all this stuff yourself![/geezer] Incidentally, there's some truth to that... 4 CIMs weren't an option until my third year on a team.

Man! Now THOSE were the days... We'd spend 2-3 weeks just getting the drive train to work.

Now, so as to not hijack this thread, I'd like to have a set of hole cutters like these: http://www.mscdirect.com/product/details/98332570 but 5 thou undersized so that we could press fit bearings into the hole.

Toolpost Grinder? I recently ran into an issue tapping a 1/4-20 hole, had to tap past the shoulder and had no reduced shank tap. Put my tap in the Bridgeport spindle and a Die Grinder in the vise and reduced the shank in about 15 minutes.
Good times.

[Munchskull]

How about a servo version of the CIM everyone would love that.

[Jared]

Double 25 sprockets, 3mm pitch belts/pulleys with 3/8" hex and press fit for common FRC motor shafts, steel on brass worm gearbox, and half inch hex sleeve.

Some sort of simple system for large diameter hollow tube axles/bearing for arm joints.

[ajlapp]

Double 25 sprockets exist...in one tooth size at least.

[Scott Kozutsky]

I'd like to see vex or AM make sprockets compatible with bike chain.

It's really strong, more resistant to misalignment, more readily available, has much better breaking/joining tools and is lighter than 35 chain per linear distance. There are also a few existing mechanisms that could potentially be pulled from bikes for it.

[Electronica1]

How about a 2 inch colson wheel with hex hub (I know it is a tad random, but would help with my teams octocanum)

Plus, on the more unrealistic side:
locking mecanum wheels
A disk brake stage that stacks with other gearboxes that have a hex output shaft

That is not unrealistic at all. I would love a modular hex disk break.

Why not buy them from Mcmaster? Bike chain is ANSI #40 and 1/2" pitch right?

Not compatible with existing wheels (versapattern/1.875 hexagonal bolt pattern) and no cheap hex options. Additionally, #40 chain is physically thicker than bike chain making the sprockets incompatible.

I've seen teams mount disks to the 1.875 hole pattern adapters so that's a pretty good starting point. It's a pretty simple thing to execute and is not necessary for most games so it would be too specialized IMO.

It would also be cool to see versablocks to mount to standard lumber sizes to make prototype and otherwise cheap robots easier.

Ahh, I am not very familiar with bikes. I never knew there were various bike chain roller widths. Neat!
