Gravity loaded axes are dynamic due to the differences between with tote and without, but J1 and J4 are static constants.

Motion profile on the can grabber? So you don't bounce off the top?

Motion profile for the 4 axis arm. Can grabbers are encoder controlled via motion profile also.

Really want to see that arm in action. Hopefully I can make it to St. Louis this year to witness it first hand. :cool:

I'm looking forward to see how fast this thing operates !

It might be the 1st industrial ARM in FRC. :eek:

I seem to remember on that was kinda similar in 2005, I don't remember the team off the top of my head, but I think I have a picture at home.

wow, i guess the middle RC arms race is upon us.

I can't wait to see the arm in action. Very cool robot.

Looks fantastic! I thought pneumatics would be faster, but I guess motors do the job just as well!

Yes, because who doesn't want to re-live minibots all over again?
