Are Mad Dog and Spin Doctor the same machine?

Does anyone know anything about Symbiont and
GreenMeanie?

Good to see that there are 8 entries in the middleweight class. Any more?

Quote from the XFM site Spin Doctor Chopper style undercutter. Competes in the US as Mad Dog. my guess is there the same machine.

hi all
symbionts mine, its basically a flipper style robot built in a rush, 2 hi power wheel chair motors run at 24 volts, steel and ally construction. its a smaller version of my heavyweight which is still in construction.

The undercutter design of Mad Dog looks interesting. Is there a ball castor or similar under the blade? Its hard to tell from the photo. Does anyone out there know?

As far as i know Mad Dog still runs on a rounded point like a ball castor so its bar is close to the ground.

Just as a teaser ive dug up a video of a battle between Mad Dog and Killjoy a full body spinner armed in 1.5mm titanium with 12mm 7075 T6 aluminium supports.

I wish we werent sitting this one out!

Im in with Blazer:

80*210mm ram (producing about 512Kg of force), 2x 1litre buffers, 3/8th high flow valve, 1.1kg of gas (about 52 flips), 2x 400watt wheelchair motors powered by a Vantec RDFR23. The robots basicly done, just needs the new armour sorting (mixture of ali/steel/HDPE). At RAF Cosford it weighed 40Kg with the thin ali armour.

aaahhh when you said about info about flipper right its one i built from parts of others which were cut down, its aprox 55mm x 150mm i have no idea what force it is which is what i assumed you were asking, im using 2 ncc70 controllers taken from my heavyweight and 2 12volt x 7ah batteries basically bits and bobs ive collected over the last year or so from various friends, at the moment im guessing its gonna be right at the limit of middleweight, so i may have to fore-go armour and hope i can flip any really savage cutter or spinner before they get me.

Sean: the most dangerous opposition looks to be from the American machines which are both spinners, one is a drum spinner and the other is the undercutter.
It looks like the middleweight class is going to be exciting and dangerous even though there are only 8 entries. Seems there will be 3 spinners, 2 flippers, 2 pushers and 1 unknown (GreenMeanie.

well it looks as though my machine may come home in a bag then :sad: i cant stand spinners far to dangerous, they should stay in the heavyweight class.
well if alans robots is like mine it could be a pusher as well as a flipper because wheelchair motors are designed for some serious torque, i dont know about yours but mine is rated at 11nm to start with and builds from there, i dont know what its stall torque is ive never tested it.
anyone else know anymore about their motors?
