Roller/Gatherer Test

[dodar]

when we were testing it the farthest i believe that we went was close to or around 180 degrees but from what we did it looks like it would be great even at 360

how quickly did you rotate with it?

[dodar]

well about as fast the 4 wheel base test bot of ours would turn, when we move it to our 6 wheeler it might be different though

Haven't tried it yet. The plates we are going to make for the outside should keep it from getting away from of though....In theory lol.

from the link, the original test shows better how good it does first grabbing the ball

Actually, I meant for our water heater. A cold shower would be bad even in Hawaii......

We too tested our prototype rollers with pool noodles. Yet we found that at high speeds the pool noodle leaves some "noodle fuzz" behind on the balls. While I will not argue that it is 'damage' to a ball, we feel the residue is a potential gray area or complaint that may arise at competition. Ergo, we will test a different material this week.

I'm interested to see how the heating pipe insulation holds up at speed.

Hmmm, thats odd, because we never left any fuzz or lost any of our noodles when we were testing it

We are currently testing/prototyping something very similar, except we are using PVC pipe at the moment. It's working pretty well. In fact, here's a video of the concept (it isn't on the robot yet).

Hmm, perhaps we have a lower quality noodle? Guess we have to use our noodles to solve this conundrum...

define high speeds?

The roller tip must match or surpass the maximum linear speed of the robot. This keeps the ball in front of the drive train with the roller while driving at max speed. If the roller tip is in excess of the drive train speed, then you will be able to 'dribble' the ball while driving at max speed.

[dodar]

That makes sense but i think what he meant was how fast was your motors spinning your noodles when you lost part of them?

I know last year when we were putting our bumpers together we had noodle issues with them flaking apart figured it was the fact they were from a lot we bought several years prior. We purchased new ones and did not have this issue.

Y dribble when u can posses?
