paper: FRC973 2009 and on robot CAD files

[robodude03]

I loved Raptor! It was tough losing to you guys at LA that year and it taught us a lot about how to play the game. Honestly you guys taught us how to win and led us to our first regional win that year.

I always look forward to checking out 973's bot during the regional competition. We will definitely be trying out some of your designs in the off season. See you at IRI

Great robots, and thanks for posting all the CAD. I certainly don't expect anybody to give away so much information, but am very grateful for it.

I assume the rack on your 2011 proto bot was custom, given it's look and your team's track record of making their own gears. Would you mind giving some tips on how you do this? What kind of equipment and sponsorship does a team need to successfully cut their own spur gears and racks? Just putting something like this on a robot is prohibitively expensive for most teams.

Also, kudos for putting two gears on the CIM shaft. Great idea/design.

Speaking of those two gears on the CIM shaft, I remember looking at the smaller one and thinking it was going to fall off it was so far out on the end of the shaft (hanging about half off). Do you have some shaft extension or coupler going on there, or is there something else I'm missing? Or is it just not a big deal?

The rack gears are cut on a conventional waterjet. Most waterjets should be able to cut such features, just with varying quality/taper.

Some parts got lost in the conversion to .step, one of which was the hex sleeve we pressed onto the CIM shaft to accommodate both gears.

We saw the 2012 greybot: Encore at the central valley regional. It was such an amazing robot, we were wondering if the CAD of it was going to be released?

Very impressive robot!

It will be, can't commit to a specific date as it requires some cleanup (there are a LOT of systems on that robot....). It'll probably be up by July.

Are there any plans to release the CAD file for Hurricane?

[AdamHeard]

Yes, at some point we will get Hurricane and Encore posted.

[AdamHeard]

Added the drivetrain for Hurricane. We'll get something cleaned up and posted for the entire bot sometime down the road.

This CAD is pretty accurate for our drive, but doesn't show that we switched to 6" wheels down the road. We changed the gearing of the gearbox (kept the same plates) during this switch. We also had a kickup cylinder (dropped a ballcaster to the floor on one end) to get out of T-bone pins.

I have two .zips for Encore that aren't working in terms of uploading, I talked to Brandon about it and I'm sure we'll get it worked out.

Adding more robots here...

2015 and 2016 are up, will get 2012-2014, 2013 offseason, and Skystalker-er up at some point too.

Awesome, thanks Adam

Thanks for providing all of these great resources for teams.

On a side note, did you ever post the RAMP files that were used in the videos? A group of my students are working through the videos, but we haven't been able to find the files anywhere. The videos are really great. The students have learned a lot from them, and I even learned quite a bit.
