This is Cornelius VIII which will make it's debut at GLR this weekend.
4 drive wheels with a big ramp and a gripper that can score on all three levels.
Nothing too exciting... ;-)

If that performs anywhere close to last years' robot, you'll do very well this year. That ramp looks huge! I'm trying to figure out what the back portion of it does, the side that's mounted near the base of your elevator. Do both the elevator and that fall down to create a longer platform?
On a somewhat non-technical note, what material do you use to cover your bumpers, and how do you print your sponsors and numbers on them?
Looks great, hoping to catch some video of it this weekend.

Thanks...
We got our bumper silkscreened this year. Last year it was a lexan sticker, but that wouldn't conform to the standard bumper rules per the Q&A so silkscreening it was...
Yes, the mast lays down so we expand in all directions... And the mast/arm is actually the front...

Don,
It's a pleasure to see the robot on CD before competitions.
Great work. are you in the 4ft class? Are there "drop-down" casters like 469 has had previously?
On the comment note: Congrats on the new robot. I have a feeling Cornelius will make many friends at GLR (and hopefully not too many enemies)

Re: pic: Cornelius VIII - FRC469
No, no drop-down casters this year...
Yes, we are in the 4ft class.
We hope to make many friends as well. We've made it nice and easy for other robots to climb aboard...

Unfortunately, no... In 469 tradition, we have to finish something up on Thursday...

looks awesome once again.... Too bad we can't play together until championships

Being the driver of a rampless robot, I'm really like some of these huge ramps I'm seeing from veteran teams.

While the metal grating is ideal for traction-wheeled teams, will your ramp provide any provisions for improving the chances of omni-wheeled teams at getting up?
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.

Don,
Can't wait to see it/you in a few weeks. Looks like a winner.

No problem about the questions, And yes we were under weight and its our secret, not really but very conservative to some areas you can take off alot of your weight. Thanks for all the positive feedback.

Re: pic: Cornelius VIII - FRC469
Don,
what do you think about adding some traction to the ramp for improved traction for those omni-wheeled robots.

Yes, we can pick up from the floor and from the back wall... The ringers are held mostly horizontal...
Yes...it would be nice to play with the Killer Bees... I don't think we have since I've been on 469...
Looking forward to this weekend as well!!

There should be a camera and a working autonomous.
Indeed, weight was a great concern. Everything on the robot was made as light as possible, such as the gripper, which weighs less than 2 pounds, and the elevator motor mount, which was made of stamped 1/16th aluminum. If we were to somehow be overweight, there's pretty much no more places to drill holes without making our robot a crumple zone.
To be fair, I credit some of the ideas to other great teams who have been able to shove a ridiculous amount of features on a 120lb robot. I had 33's short-lived stamped-steel swerve drive modules from 2005 in mind when I worked on the motor mount.
Wait until you see it move. It'll make the weight seem even more impressive.

Don,
The similarities are eerie. Knowing that we're on the same page as 469 makes me feel really good about things.

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.
