FRC973 2009 and on robot CAD files by AdamHeard

[R.C.]

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!

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?

[AdamHeard]

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.
