Maximum Angle for Ramp

FIRST General Forum
1

We are trying to determine what the maximum angle other robots would find acceptable for a ramp. Our rough numbers indicate that a robot that is 28 inches front to back with a center of gravity of 27.5" inches up should be able to go up a ramp approximately 19 degrees without tipping. This has led to discussion as to what is the max acceptable angle to design for other robots for speed in climbing, not tipping, and not beaching. Also what would be considered the ideal angle.

We know it is dependent on a multitude of factors, but trying to get some outside opinions.

Maximum angle should be the same angle of the ramp leading up the platform. That way any robot that can climb the platform can climb your ramp.

I would highly recommend this advice, so that any robot that can drive up the platform can drive up your ramps.

I would also caution that the limiting factor for most robots will probably be their bumper clearance, not their CG. Bumpers are limited to being pretty low this year, 2" maximum ground clearance, meaning going up inclines and cresting over the top is not trivial.
