Better late then never I suppose. Here is our 2007 Robot.
The image in the top left shows a view of our 14 wheel drive and our Carbon Fiber "Riser".
In the top right is an image of our arm mock-up (I didn't have any good shots of our finished arm but it's basically the same only made out of lexan and aluminum).
The bottom left image shows our robot with ramps in the starting configuration just before we shipped the robot.
And finally the image on the bottom right shows our ramps fully deployed (Not all of the side rails were installed when the picture was taken).

I have always liked 703's drive train and design sensibilities in general...keep up the good work! I was trying to get 461 to use carbon fiber/nomex panel for the ramps but it didn't work out.
What is the "sandwiched" material in your panels? Nomex? Aluminum? Something else?

Thanks, we're very proud of our drive train this year. Our goal was to fix the issues we had had with our tracks breaking in previous years robots, so instead of dealing with all the belts, we just came up with this. It simulates many of the advantages of a tread system and adds the reliability of gears and wheels.
We used Divinycell foam for the sandwiched material as it had much more compression strength than typical Styrofoam but was still very lightweight.

That bottom left one better have the ramps slightly out of starting position, or you've got some work at your first event. (If the ramp on the right is in the box, that's an awfully small robot.)
How do you deploy the ramps? Did you keep the arm (I can't see it in the bottom two pictures)?

Are your wheels in a gentle "U" shape? My team is trying to perfect our drive train for next year so we are looking around. Would you recomend this?

Yeh, we solved that problem by pulling the ramps in so they fit square inside the starting configuration, We just didn't have the cables attached in that picture.
The ramps get deployed by being retracted up and to the center of the robot by our winch system to a point where they are no longer restricted by the bumpers, our spring hinges then take care of popping them out and we then reverse the winch to allow them to slide out.
It isn't the fastest process (takes about 5-7 seconds to deploy fully) and we had a few issues with it in Detroit which we believe we have addressed (deploying early, getting stuck, ect.).
We did not attach the arm in Detroit, we knew we had to make an new mast for it after we shipped it in order to make weight at the regionals and because the gearing needed to be ajusted, we just never got the time to attach the new mast in Detroit due to all the troubleshooting we did with the ramps.
I'm hoping we can get it on for West Michigan, if not, expect to see it at least once or twice at Nationals.

God, I love our robot. It was amazing in action at Detroit.

I didn't have a video camera there and our team videographer couldn't make it, though I think a few members did take some video so I'll have to ask around a bit to find some.

Yeh, I figure since we've been to a regional now there's no sense in keeping it a secret any longer.

Watch out for this robot. Galileo, time to learn about defense the Saginaw way! These guys will push you 90% of the time.
