Right, I feel like I should join in and create a vapourbot...

Gross Surgical Malpractice
Weight: 100kg
Shape: T shaped undercutter, similar to Totally Offensive / Relic. You can see a photo of Totally Offensive here: http://www.madoverlord.com/lg/DSC041/DSC04135.jpg
Colour: Bare titanium.
Dimensions: 110cm(60cm long main body)x80cm(rear spar)x15cm at its highest.
Drive: 2 S28-150 Magmotors powered by a shock mounted (batteries linked by flexible thick copper braid, and each battery pressed into a hole in a block of thermally conducting rubber similar to a flexible potting compound) 24v pack of A123 lithium cells, geared down through a couple of Team Whyachi drive gearboxes. The Magmotors have custom machined inserts designed to stop the magnets becoming displaced. All electronics are shock mounted as best as possible, isolated using rubber and their components potted to avoid impacts removing them from the PCBs.
Locomotion: Two 5 inch Colson wheels, driven from the gearboxes with the axles supported both sides by bearings.
Armour: 12.7mm 6AL-4V welded main body with 19.05mm bulkheads, 4.8mm top plate, 6mm wall thickness on the rear tube spar.
Speed: 12mph
Ground Clearance: 5mm under the undercutting blade, 20mm+ elsewhere.
Turning Circle: Zero
Weapon: 1m long, 10cm wide, 3cm thick 25kg Hardox bar with S7 tool steel teeth. This is spun by a 50hp Aixro XR50 294cc rotary kart engine at a 4:1 reduction, resulting in a top speed of 2700rpm and up to 300kJ of kinetic energy with the perimeter weighted teeth. The motor is electrically started by remote control and has undergone considerable weight reduction surgery.
Srimech: UHMWPE self righting hoop
Strength: Excessively powerful weapon.
Weakness: Very exposed to the rear. All the driving that's required is to keep it pointed at the other robot, though :twisted:
