Re: pic: 2980 practice bot Climber

I like the way your drum (at least it looks like) rotates so that you get a couple of wraps before there's load on it. But I gotta ask, what kind of bolts are you using. Because it looks to me like to get that rotation on your drum your entire climber is held onto your frame with two bolts.

This means to me that the failure point of your climber is those two bolts, if those bolts aren't strong enough they will shear and it will be a really bad time. 150lbs of robot on two bolts seems like a likely failure scenario to me. You should be able to buy bolts with that shear strength, so it should be a (relatively) simple fix.
