Team 1029, yes, there will be some kind of guard rail once we get the whole ramp working.
Josh, it’s lexan. I wouldn’t say its very grippy, but our last year’s robot had no problem climbing up that ramp. If traction becomes a problem, we will put some stair tread on it.
Dan, yes, there is a bit of deflection in the back, if it collapse anywhere, it would collapse in the back. The plan is to have U shaped legs for supports instead of just one 1x1. Ran some calculations and it will hold atleast 180 pounds. I don’t think anybody’s bot will be more than 150. We drove the robot up the ramp, not place the robot on it. We ran into the ramp full speed (which was probably about 7/8 fps) and with 2" of clearance (last year’s robot), the robot didn’t have any problem getting up the ramp. Dan, you already know how much I beat the crap out of the robot during build, so it doesn’t break during regionals.
David, you guys are welcome to climb up our ramp. =)
Brad, we will have two ramps. One on each side. Students just build one of them yesterday, so we could test it out. We should have the other one done very soon. Stay tuned.
