Nifty! I like the single reduction and the angled module approach you're taking. Needs more Shellac. And mind that ground clearance.

I'm also really jealous of your laser cutter... that's got to be one of the most useful tools you could have for a 6 week build season.

+1 on the laser cutter. How long does it even take you to cut out your chassis? It's crazy how fast you guys can get stuff done with that thing.

Our off-season chassis took about 4 hours of laser time, including setup. This module took 9 minutes.

It's a pretty neat tool to have; we can make 2D parts faster than literally any other team.

Edit: At least as fast as any other team.

Well, that is assuming no one else has access to a laser cutter.

we just have to assume that no one else does, because we only see 4183 posting pics of all these neat parts

Honestly because we have one now working without one would be extremely hard, if you have a lot of extra money (ha a first team with extra money) I suggest getting one, they are useful in most situations and cut time in design, fabrication, and programming by quite a bit.

Thats a neat looking encoder. Do you have any experience with it that you can share?

This year is our first time using them, but there's some information here.

This is the model we're using; I believe they're also available in FIRST Choice.

1899 makes almost fully-wood robots every year.

That kind of speed makes me want to abandon our bridgeport and buy a laser cutter.
But the team probably wouldn't have the heart.

Why geared so fast?

Why not both? Never give up the mill....

I would take the mill home.
We might get rid of our old Grizzly lathe in favor of something that can actually cut steel in a few months, so a hobby machine might be coming my way already...

I remember reading your laser cutter is 29x17", but how powerful is it?

We're using Killough drive, so robot speed is 1/sqrt(2) wheel speed. We also like the simplicity of a single reduction gearbox.

I'm not certain; I think 60 or 75 W.
