FRC973 2009 and on robot CAD files by AdamHeard

Re: paper: FRC973 2009 and on robot CAD files
 

Hands down some of the coolest FRC Robots of 2009-2011. 2009 is especially my all time favorite for that year.

Congratulations on winning the 2011 FRC Championship, it was great working with you guys this year. Can't wait to see the 2012 Proto and 2012 Robot!

*On a side note, I really want to thank 973 for helping 1323 gain more sponsors, become a better team and for also helping us throughout the past few years*

Ah, Raptor, one of my all-time favorites. Great to see more CAD from you, Adam. This year's been great, seeing 973 get the recognition it deserves is just awesome. I know RC and I are thankful for how much you've helped us in the past few years as well. Thanks for the CAD.

Ahh, 973 just has a way with producing some wicked fine california robots! :rolleyes:

Re: paper: FRC973 2009 and on robot CAD files
 

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.

Re: paper: FRC973 2009 and on robot CAD files
 

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?

Re: paper: FRC973 2009 and on robot CAD files
 

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!

Re: paper: FRC973 2009 and on robot CAD files
 

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.

Re: paper: FRC973 2009 and on robot CAD files
 

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

Re: paper: FRC973 2009 and on robot CAD files
 

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

Re: paper: FRC973 2009 and on robot CAD files
 

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.

Re: paper: FRC973 2009 and on robot CAD files
 

Awesome, thanks Adam

Re: paper: FRC973 2009 and on robot CAD files
 

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.

Re: paper: FRC973 2009 and on robot CAD files
 

That is an impressive set of frame gussets in each corner of the robot. Thank you for the release!
