It wouldn't surprise me if this was considered part of the challenge. If in fact though the edges can spin, then any height advantage gained by grabbing an edge would be lost. (your arm has to extend to a little less than 9 feet, if you're doing an arm that pivots at the base of the robot)
The tetras are glued together and the bolts in them have loctite. This should not be a problem.
