Right... here goes for ludicrousness in the field of spinning stuff round really fast...
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 2000rpm and up to 175kJ 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:
And another one as somehow I am meant to have two according to some people - not to mention, someone needs to show Mark what a real vertical disc is :twisted:
Vertical Limit
Weight: 100kg
Shape: Vertical spinner - a wide wedge-shaped body with two large support bulkheads extending upwards either side of the centrally located disc, with front titanium fork skids extending from these bulkheads to get underneath opposing robots (by concentrating the pressure exerted by the robot's weight) and transfer the recoil from the disc impacts to the ground.
Colour: Bare titanium and carbon fibre, with a mountainous landscape anodised into the front wedge.
Dimensions: 35cm(h)x90cm(w)x45cm(l).
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 6 inch Colson wheels, driven by chain drive from the gearboxes with the axles supported both sides by bearings.
Armour: 6AL-4V titanium front wedge cover 4.8mm thick, 60mm (pocketed) 7075-T6 aluminium main weapon support bulkheads. Carbon fibre/kevlar composite top, side, and rear armour. Two bolted in 6AL-4V titanium front forks, with 30mm wide ends, which direct opponents into the disc and transfer the recoil to the ground.
Speed: 15mph
Ground Clearance: 0 at the front, up to 10mm at the rear.
Turning Circle: Zero
Weapon: Tiernay TT-10 125hp turboshaft engine powering a 20kg 300mm diameter, 50mm thick hardox vertical spinning disc with a single S7 tool steel tooth. The disc is driven by a belt-based CVT (continuously variable transmission), assuming 80% efficiency and the engine running at the peak of its powerband kinetic energy is transferred into the disc at the rate of 73.6kJ/sec - let's say up to a peak spin speed of 8500rpm, with a KE of 375kJ which is reached in ~5 seconds whereupon the spinup rate rapidly drops off.
To give people who chuck insane spinner kinetic energy values about some kind of idea what they mean - if a quarter of the energy of that disc was imparted to an opposing 100kg heavyweight in a vertical direction, it would chuck them 95 metres into the air.
Self-righter: Bouncing about on the disc, in addition to a self-righting arm powered by a powerful brushless inrunner motor and reduction gearbox running as a glorified servo.
Strength: The most powerful vertical spinner ever. :twisted:
Weakness: Rear attacks, potential structural damage caused by weapon impacts.
Right, that should just about do for stupidity and impracticality... I think I won't post in this forum for a bit.![]()

Has a nose cone and two giant ears to help keep opponents on the wedge, and to help with self-righting. The main weapon is a front-hinged flipper that can lift nearly 3 tonnes and has 30 full power flips. On either side of the wedge are two spikes made of S7 tool steel which also help with keeping bots on its wedge. They can also thwack using the decent drivetrain of Gabriel V. It's 4mm Hardox armoured and has a thick steel chassis, but it'll run out of flips eventually, and its base armour is weak.
