Since there are published dimensioned drawings of the sensor assembly, I wouldn't consider a non-trigger due to striking a bolt to be a tower malfunction. I would consider it to be a deficiency in the design of the minibot.

Given that the bolts don't move, a properly designed minibot will avoid contact with the sensor plate in an annulus with an inner radius of 4.5 inches and an outer radius of 5.5 inches (assuming fender washers of 1 inch diameter). Otherwise you risk hitting a bolt (or washer).
