Team 341 "Miss Daisy" presents Miss Daisy 10 (our 12th robot, and 10th named Miss Daisy).

Video will come shortly. I am tremendously proud of the hard work of our students and mentors this build season.

Stats:

* 6 Wheel, 6 Motor Drive using 4" diameter/2" wide IFI wheels with Blue Nitrile tread (13 fps top speed; traction limited at stall). Turns effortlessly. The best drive train we have ever built.

* Arm shoulder joint can reach all scoring levels from the ground in <2 seconds, including scoring over the robot's back. Dual gas springs keep the arm nearly weightless to the motor.

* Pneumatically articulated wrist deploys claw for pickup and retracts to protect it during transit.

* Wide sensor-controller roller claw powered by an RS-775 effortlessly picks up any tube, in any orientation, at any robot speed - all the driver has to do is touch any part of the tube. Geometry of the claw keeps the tube at a constant orientation. After 4 primary iterations and over a dozen minor versions, this is the best manipulator we have built.

* Entire claw can be swapped out in minutes (we are pragmatic about the inevitable fate of floor pickup mechanisms this year...).

* 2-step minibot deployment process (lock to tower, deploy minibot) that takes any chance out of deployment.

* 37 x 27 x 59 x 115 lbs

Looks like another awesome Miss Daisy. Can't wait to check out the video. Too bad you guys aren't able to attend NY this year. Good Luck with your awesome bot in 2011!

Yeah, just edited the post - don't know why the rest of the description got cut off.

Looks great, cant wait to see it at Philly!

Any pics of the drive train gearboxes? I am interested to see how you are integrating the RS-775.

How did you use 6 motors in the drive train when the maximum number of symmetrical motors are 4 of each type (CIM or Banebots)

I'm intruiged!

Looks like another great robot from you guys! One of the few perennial powerhouses from a non-Michigan area.

Nice work!

See you guys at some event this year!

Is that a blue BaneBots wheel I see on your gripper?

RE: Drive

We are using AndyMark Nanotubes with custom ratios and #25 chain between all three wheels on a side. There are 2 CIMs and 1 RS-775 with a CIM-U-LATOR on each side. The drive is incredibly redundant - each motor is direct driving one IFI wheel via its own gearset, and is chained to the other two (the Nanotube has all of the necessary holes for mounting a third Toughbox Nano gearset in the middle). We could conceivably lose both lengths of chain and two drive motors on a side, and still be able to move.

RE: Gripper

Yep, those are BaneBots wheels. What they grab shall not be dropped!
