I can't tell from the picture, but the section of the ramp that deploys from the rear one piece, or does it have a gap in the middle?
Is the device sticking out of the ramp at the rear just to ensure that your ramp doesn't become a "traction device", or does it raise the whole ramp to 12"?
Can you load tubes off the ground, or just the wall?
Is there a camera that I'm missing, is it coming later, or are you guys not using it?
What motors are used where, and are you using DeWalt transmissions again?
And of course, the perennial 469 question, HOW DID THAT MAKE WEIGHT!?! 
Sorry for the tons of questions, but 469 is really one of the more inspiring bots every year, and I'm dying to learn more about Cornelius. Good luck, I'm sure you will be a force to be reckoned with at GLR.
Hope you can pull off the ramp-ringer combo, nobody really has yet. |
The rear ramp deploys as a whole piece. The cutout that you can see in the picture is just there in order to give the arm a spot to fold into. We have also had several discussions about traction material for the ramp but it is a low priority for us at this point.
The devices on the ramp are in fact for lifting it to twelve or so inches. They are, however, not complete as pictured.
The gripper itself, as I think Don mentioned, can grab tubes from the floor, the wall, and, theoretically at least, from the HP over the driver station wall. The mast rotates to make this possible.
The camera should be along shortly. We actually didn't have any time to work on it due to more... pressing, programming issues. Our plan is to still use it at least for auto.
We are again using 4 dewalt transmissions on the drive and plan to servo shift them again this year.
Weight wise, we used as thin and light material as possible everywhere. There are almost no pieces on the robot thicker than 1/16th of an inch. Even parts that needed thicker walls to support holes, like on the gripper, are only 1/8th thick around the hole and milled down to 1/16th everywhere else. The round tube, of course, is even thinner. It really was a situation where we thought about weight in everything we did.

btw, if any of this turns out to be a "secret" don't tell them it was me who told you
