Um, thanks to all for showing me that square robots don't (easily) fit into round holes. While this doesn't prevent an arm, it certainly adds to the challenge of using one.
Deploying minibots won't be as much of an issue: If I have an 8" square minibot, I have about 3" between the edge of the minibot and the pole (assuming minibot is centered on the 1.75" pole). 18+3=21, I only need 15-3=12. Maybe a 24" stroke pneumatic piston to whack the minibot onto the pole....
Inspection: I propose that we supply 60" I.D. right cylinders of infinite height to each venue for inspection. OK, even 30 feet tall would be impressive...
