Re: Ramp Angle Survey
That's really a moot point. From driving previous robots, I've noticed that motor stall and joystick sensitivity at low speeds is a BIG issue. Since I imagine you don't want robots climbing at high speeds, then you're going to be dealing with robots turning on your robot no matter what.
I think it a plausible sequence would be like this: -Team is driving very slowly up skinny ramp -Team stops to make sure orientation is good -Team attempts to continue at low speeds, but one side un-stalls first, causing the robot to rotate. They now either have to deliberately rotate, drive off and try again, or just give up and hope they reached 4". Which makes me realize that painted-on markings for vertical displacement of 4" and 12" on any given ramp would be a very good idea. Also, having your ramp removeable between matches would be good. Who wants a 4ft ramp above their heads if they know before their match that they'll be climbing an partner's ramp? Quote:

Re: Ramp Angle Survey
I like the info posted here, it will be very helpful to us, as we are designing a rampable bot, hopefully capable of holding two others.
Here's an idea for you all to consider- what if, instead of a flat ramp, you had a curved (or maybe even parabolic-less trouble with that leading bumper edge) ramp. l believe that this could potentially allow a shorter (in length) ramp to accommodate a longer/less ground clearance wheelbase, especially if said ramp was parabolic rather than a perfect circular curve. Just a thought. Let me know what you think. |
