Complex Spinner
Complex Spinners are virtually always HS types, and involve placing spin motors on to other spin motors via a disk or tri-bar. Complex spinners can be either parallel or perpendicular. Starting out from a horizontal spinner (a vertical source just self-destructs), stick either a disc or bar, then mount another set of motors. If the axles of this second set are still like horizontal spinners, then this is the parallel variety. Perpendicular are if axles are angled outward (90 degrees to the source), like rotating face spinners. The advantage of this design is that even if the main spinner is stopped by a ram, the outer spinners often still rotate. (The Battlebot AI pack's Phrizbee and a some of the Starcore bots are complex spinners)
Strong: Boxy, exposed chassis bots Weak: Well-armored machines
Pro: Very difficult to completely stop Con: Difficult to build, incredibly unstable
