View Full Version : Ramp deployment a hazard?

Is a robot allowed to simply use gravity to deploy its ramps? We are considering a mechanism that releases our ramps and allows them to fall like wings on either side of our robot. Or would this pose a safety hazard, and require it to be done in a controlled fashion (e.g. pulley and rope system)?

Change in altitude of CG (gravity usage) is a legal source of power. If they come down too fast, put a brake on. If you think it's a hazard, the inspectors might also.

I'm no inspector, but the main hazard to me seems to be the thing deploying accidentally off the playing field. As long as you have a pretty good way of ensuring that it won't smack someone when you're standing in line or working in the pits, I'd say you're fine.

This question has been covered in the FIRST Q&A System (http://forums.usfirst.org/showthread.php?t=1608) in the "Ramp Question" thread (http://forums.usfirst.org/). Gravity deployment is OK, but there is a caveat. So read the answer carefully.

If the ramp has the capacity to damage another robot seriously (to the point of malfuntion). Then I believe it would be considered hazardous.

The GDC has said "done in a safe manner (Rule <S01>) and must be controlled so that it does not damage the field (Rule <G34>)". They didn't say controlled so that it does not damage another robot.:ahh:

If the ramp is capable of damaging a 135 pound aluminum robot, then it clearly is also capable of damaging the field.

I wouldn't say that is necessarily true.
