Team 1351 Ramp Design Help

[Sam N.]

Can anyone tell me the angle of their robot's ramp? Is it made from metal or wood? How much does your ramp weigh? How does it deploy? I only ask these questions because our team may be in trouble with our arm and may resort to using a ramp.
WISH US LUCK!
thank you for your replies

753 is building a ramp this year, to complememt our forklift and track drive.

We're using 38'' square sheets of carbon fiber we had donated by a local aircraft body firm, cast in resin with a paper laminate in the middle. They weigh 3.6 pounds each, which fact was a nice surprise to us. Obviously this is not easy to get on short notice, so you'll have to go some other way. Maybe metal mesh; lots of teams are using that kind of stuff.

As far as extending them, we have them hinged along the top left and right parts of the frame. They both flip down when a pneumatic piston in the frame levers them out and slides a restraining pin out of its holder. Pictures soon.

One of the two pieces has footlong feet at the corners to hold it up as a flat piece, and the other drops to the ground to function as a ramp. The ramp angle will be about 17 degrees, which is much shallower than the ramp for last year. Plus it'll have jar gripper rather than diamond plate.

I hope this helps. I really enjoyed seeing your '06 bot last year, and I hope we can see something good from you this time around.

Ari.

Our ramp is approximately 12 degrees and goes up 8 inches onto a platform and we use two 2-inch diamater pistons to lift the robot the remaining four inches. It is made out of grating and 1-inch Aluminum angle.

Team 1583 (which is a defensive ramp bot) has a 20 degree ramp that is aluminum. Check out the video of it "doing its thing" at the Denver area scrimage yesterday.http://www.youtube.com/watch?v=NTu4S9sSAvM

At the beginning of the season, some of the students on team 1033 worked on a prototype of a two sided ramp. Our chasis is 12 inches tall so the idea was to drop 2 pieces of 1/8 thickness diamond plate down to the ground using two pneumatic cylinders. We supported the sheets of diamond plate by welding support bars on the side of the sheet so that the plate wouldn't bend downwards.

If you scrap the arm idea you could go for the 6 ft height and if you do your trig right can actually make a ramp on one side with a 14 degree angle and a place to support two robots on the other.
