This year i had to power our arm with two rs755 mated with cimulator and a tough box plus 3:1 chain reduction to make up for the lack of gearing.
There's also a 2:1 gear reduction in there after the GEM, which makes the total reduction 889.2:1.

It works surprisingly well, but one thing we've discovered is that the GEM won't backdrive (the radial load from the gear it drives causes the output shaft to bind inside somewhere), so we use a big wrench when we need to move the arm without power.

Pat, do you guys think you'll be adding floor pickup?

We're going to see how Pittsburgh goes as is, and then re-evaluate after that since we have three weeks before our next event.

Personally, after spectating at FLR, I'm still inclined to believe that we can be sufficiently effective without.

Aaaand 1503 proves you don't need floor loading to dominate at a regional.

I just finished watching the Pittsburgh regional. You guys did great! Very well done. Seeing you guys run with 1114 was absolutely amazing. You guys have a very solid robot. I'll be watching GTR for sure, can't wait to see how you guys do.

Best of luck!

Thank you very much! It was really cool to win with an old friend, it was nice to be on the same side of the field during eliminations once again.
