Okay...
This is THE COOLEST FIRST design I've seen in a long time.
I was shown this on Thursday at UTC, and have been smitten ever since.
Andy,
You got it 1/2 right.
For those who haven't seen it yet -- RAGE actually uses the cable carrier to extend and retract their arm. I won't steal ALL their thunder, and post the details -- perhaps Triggs can enlighten everyone.
It is SPECTACULARLY cool. Soooo smooth, soooo simple.
After fighting with cable/pulley's last year for our extension, I am AMAZED by how simple and effective this is.
The best part? It manages their cables/pneumatic tubes WHILE is drives the arm!
Seriously --
This entire robot is a work of art. The sheet metal arm design is one of the best I've ever seen on a FIRST robot. Combined with their great end effector, and this innovative extension, it is truly an incredible machine.
RAGE--
Kudos on an incredible machine. I was SHOCKED when you didn't win a technical award at UTC. You've definitely inspired me. (Not always a good thing!)
Everyone Else--
Go check this thing out. Seriously, if you get the chance, take some time to go visit 173's pit. It is worth taking a walk over.
Again -- Kudos to 173!
