Re: [Ri3D] Help BOOM DONE. order stuff

Window motors!
Where am I going to get Denso window motors? They are only 20-30 Watts but sometimes they are the PERFECT motor for the job -- and they are not backdriveable. Well, mostly non-backdriveabel. I remember 177 had a huge and awesome ball gripper in 1996. I think it was driven by two window motors and, to my great surprise at the time, if their arm was horizontal when the power when off, that gripper fell!

Anyway, I have no idea what sort of robot we'll be designing but odds are I will want some of those Denso motors. Any teams in the Boston Area willing to loan/donate a couple to BOOM DONE.?

PM me. I promise a shout out to you in one of our videos, whether we use them or not.

I have a couple I can send you if no one up there responds. We don't use them often enough to keep them around and if we need them I can get them from other local teams.

Thanks. Also, for the record it was 1998, not 1996 that The Bobcats had that awesome ball roller gripper thingy that we powered by two (I think two) window motors. That was the year we first had swerve, Chief Delphi won all three Regionals that year and not coincidentally the last year FIRST used the 1 vs. 1 vs. 1 format... It seems like it was only yesterday...

Hey Kid! Get off my lawn!!!

Joe,
Check here... http://electronics.mcmelectronics.co...p+wire&x=0&y=0
This is NOT your normal zip cord.
And 1996 was not that long ago...

Zip-ties! They allow you to easily fasten things like wires to different structural components, cleaning up your electrical and some other stuff up!

I was about to correct you on that.
Also we still have that robot in storage. I wish we had the control system to run it.
Through the miracle of CD here is a picture of the claw you mentioned.

We used derivatives of that design through about 2005.

Wow. That picture made my heart start racing. I remember seeing that middle goal fill up SO fast when you guys were on the field. I'd blink and there was no more room to score. That was a fearsome robot.

Remember the Nationals that year with the Losers Bracket from Hell? We were knocked out early, but then about 10 amazing teams all dumped in there at the same level. I think you guys were in there, and Wildstang, and Beatty, and TechnoKats, ... That was a bracket for the Ages.

We have a bunch as well and we picked up a host of the couplers during FIRST Choice last year. The motors are very useful for simple mechanisms. The internal worms tend to break if you backdrive too hard though
