FRC148 - 2011 Robot Assembly - "Raptor" by JVN
I've posted the full CAD models of the 148-2011 Robowrangler Robot - "Raptor."



Of course, the CAD models don't fully represent the final product. There are always little pieces that get changed along the way, and no matter how many times I say we "CAD everything" we almost never CAD everything. I tried to spruce them up a bit but they're still missing some pieces. Enjoy!

Thanks JVN! Always fun to take the robot tour on your own from the comfort of your own computer.

This one gets my vote for most impressive robot of the year. Thanks for posting this along with your blog entries. It's really cool stuff to take in.

Thank you JVN and the entire Robowrangler team.

Thanks for posting.

Downloading 148's robot is one of my favorite things to do every year.

I looked at the model, and I can't figure out what propels the minibot forward? Is it some sort of spring? It looks like there is a release cylinder, but I can't figure out what it does.

Lots of surgical tubing.
We connect the surgical tubing from the cradle that the minibot sits on to the tip of the "Y" which aligns to the pole.

Since the surgical tubing is held on with zip-ties... we don't model it.

Can you post a picture of this then please?

Another great robot comes out from 148!! hey is there anyway i could import the mates for the assm.?
But seriously, i love this thing.

Has anyone else found the nonagon shaped holes on the "hip joint" linkage? I'm thinking John was having a little fun with this. After all, it is a championship winning shape.

Also, those 11 tooth CIM pinions have got to be really nice, expanding your range of possible reductions by nearly 10% !!! over the commonly available 12 tooth pinions. Since most teams have access to an arbor press or something functionally equivalent (they're not too terribly expensive anyway), I've been thinking this would be really nice to have commercially available. Maybe something for AndyMark to jump on? They are particularly useful in drivetrains with CIM motors, because they allow you to get a reasonable reduction with just a single stage.

I saw this on there 2010 robot, haven't looked at there '09 robot. But i defiantly think JVN and the wranglers have something with 9-sided figures, we have even seen a drive train from them called Nonagon!!!

[JVN]

I received a question via email...
The model includes (5) CIM motors. The arm motor was actually a Banebot 775 motor run through an AndyMark planetary gearbox.

Brief Aside:
We were lucky that of the (18x) 775s we purchased we had a handful that were good. These motors never gave us any problems. The ones that came with manufacturing defects were NEVER good...

These models are always great, thank you!

To be fair, Neun means nine. Who better to invent Nonadrive?

I thought the drive train was Nonadrive...
