I know that they are not the Fisher Price motors
becuase they didn't come in the kit this year, and I
know it is not the torque motor.

Bridge Balancing for us was somewhat easy
because we programed to find the middle of the
bridge.

Thats what it looks liek to me too...

Looking at the pic i linked to... seems like there are four FP motors on there... no sure way to tell without checking out the bot.

As for balancing on the bridge, with a little bit of driving practice it can be done fairly easily...

What motor is being used to turn the front end of the bot?? This is a very interesting design... i like it, and i really like your control system (go to the page kyle linked to if you want to see the cool pics)

Yes those are four f-p motors, but please remember that this was a prototype, most of the "real" systems, including grippers will be mounted today and early this week.

As for balancing...

Practice makes perfect. The first time it took several tries, and we haven't tried it with goals yet, but it is definetly doable. If you dont have a bridge to practice with, I would sugest bugging area teams that do and seeing if they will let you practice (Feel free to use ours, if you can get down here!)

How does this robot grip the goals? I see to be missing something here.

Looking at the spinning body and everything, it seems like this robot can push the goals pretty well already, with the robot comming in all knid of angle. I suppose the robot doesn't need to pull goals/stretcher because it can always twist and move around the goal to get behind it. But you see that rod going through the back wheels? They can definitly attach some kind of gripper on that.

You guys need to read the fine print.

I seem to recall Kyle saying something like "here are
some pictures of our chassis PROTOTYPE" (emphasis added).

That is why it obviously uses 4 Fisher Price motors
(illegal) and it doesn't have any grippers, etc.

By the way, it is extremely cool. I have never seen a
drive system like this in FIRST before. There have
been steerable drives before but not one that
effectively pivots the front and rear axles in this way.

Honestly, I am not sure that I would duplicate this
drive, but it is a definite innovation.

Hats off to the Rhode Warriors!

Can't wait to see what the rest of your limbo-bot looks
like.

Props to Team #121 also for sharing their robot (or at
least a proto of the chassis) so early.

P.S. Look for CAD pics of CD 6 in about a week. Real
pictures in about 1.5 weeks (Lord willin' and the creek
don't rise).
