Eye of Ran
^{active from June 2008 to March 2009}

WEIGHT: 100kgs
DIMENSIONS: 95 x 70 x 26 cm (minus weapon)
SHAPE: A T shape, with the front end being the thin section of the T, which has the weapon mounted at the end. The rear horizontal section is about half of the robot's overall length, and has a wedge at the back. The underside armour is slanted upwards, so the body is thinner at the front end than at the rear.
COLOUR: Dark blue, with green leafy decorations, gold and green eye on top, name written in ruby red on the rear wedge
DRIVE: 2 S28-400 Magmotors run at 24v from 4 NiCad packs, driving two aluminium wheels with rubber belts for grip at the back of the robot.
SPEED: 10mph average, 16mph max
GROUND CLEARANCE: 0 at the back due to the wedge, 0 up to 80mm at the sides, and a good area of the sides and the front is protected by the blade, so while you could quite easily flip it from there, try getting in underneath

ARMOUR: Top and rear wedge is a single welded sheet of 5mm Hardox, thickness up to 8mm in key areas. The sides and underside armour are 8mm polycarbonate with 3mm grade 5 titanium behind it in areas, and to save weight there is no real chassis; instead all components are mounted to the underside of the top, with rubber between them to slow down any axe type things, and the side and bottom polycarb panels are chemically welded together. To protect it, the weapon drive train (engine, axle, etc.) is mounted in a Hardox frame with polycarb panels.
WEAPONS: A 20 kilogram 80cm long front Hardox bar/blade, which is sharpened and shaped into a hook at the ends to dig in and rip away opponents, with sections cut out to save weight as well as concentrate weight on the outside. This is driven by a redundant chain drive from a 121.6cc 8.6hp Stihl chainsaw engine fitted with an onboard starter to a maximum speed of 4000rpm, but is generally kept at 1500-2000rpm unless stated to minimise self-destruction, getting up to top speed in six seconds but powerful enough to throw in three. It should deliver an approximate maximum of 100kj, and mounted 7mm off the ground (with a ball castor in the centre of the bar itself keeping it from hitting the floor) it could seriously damage wheels, skirts, and flippers - I don't want to think about what happens if you have external tracks.
SRIMECH: Invertible. The side armour is angled somewhat to prevent it resting there.
NOTES: Components are rubber mounted (as mentioned) to minimise shock from its own and others' weapon hits. All the components (excet the weapon and its drive chains) are located in the rear box/wedge section, which helps
STRENGTHS: Decent armour, good pushing power, large area of attack
WEAKNESSES: Not the fastest, Newtonian physics

Eye Of Ran II
^{last updated March 2009}

Many many thanks to Andy Jackson for doing the awesome CAD above

WEIGHT: 100kgs
DIMENSIONS: (body only) 60 x 120 x 23 cm
SHAPE: A T shape, with two pairs of diagonal supporting bars joining the sections about halfway in, with the flat top of the T being the front. The top bar is 15cm wide and the rear section 25cm, and the axle for the weapon is located at the junction of these bars. The front is sloped to deflect vertical spinning weapons.
COLOUR: Indigo blue with green vines and leaves, a half moon, clouds, and a gold and green eye over the weapon axle. Name written on the front in red, with the II behind it in gold.
DRIVE: 2 S28-400 Magmotors run at 24v from 4 NiMh battery packs, these drive four 10cm diameter 5cm wide urethane rubber treaded wheels, in a Big Nipper arrangement, located at the far ends of the front bar, enclosed within the armour but poking through the top so as to be invertible. The rear section has a pair of castors on the base and amother pair at the top so it works equally well when inverted.
SPEED: 12mph
GROUND CLEARANCE: Below the blade is about 5mm, around the wheels and rear castors is 10mm. This is covered by small 3mm 2014 aluminium skirts underneath the sides and rear, and there is so little shape to grab onto that most - if not all - attempts to flip it while the weapon is going will result in the flipper/lifter hitting the blade and being knocked away before getting a chance to do anything.
ARMOUR: 5mm polycarbonate over a titanium/vanadium alloy box section frame, with a 5mm 2014 aluminium baseplate and 4mm Hardox top and front panels. These panels are shock mounted to absorb the energy from axes and hammers.
WEAPON: Entirely constructed from the finest Hardox with portions cut out for both weight reduction and a flywheel effect that concentrates quite a bit of the weight on the outside of the weapon, I present my undercutting 30kg, 1 metre long, hardened steel edged, and sharpened into curved hooks at the end to slip beneath the lowest of ground clearances, undercutter blade/bar.
This is driven by a modified Stihl MS880 121cc chainsaw petrol engine which produces a peak of about 10 horsepower, through a redundant chain drive and a clutch mechanism to the weapon, and at its maximum 4000rpm can produce an (entirely theoretical) 235 kilojoules per hit. Kept at a saner and more sensible level of 2500rpm it produces just over 90kj, which will be its maximum level in fights unless I say otherwise.
Because of its positioning it has a reach of about half a metre in front of the robot, and it is also impossible to attack any part of the body (unless an axe or similar is used) other than the very ends of each of the body sections without coming within its reach.
SRIMECH: Invertible. The unusual shape gives no areas in which it can rest without falling on either its back or right way up.
NOTES: All the components inside are shock mounted where practical to reduce damage from opposing kinetic energy robots, as well as its own hits. The clutch on the weapon should also help in preventing huge shocks being transmitted through the chassis.
STRENGTHS: Very dangerous weapon, virtually impossible to attack without coming into reach of it. Good drive and very good traction due to the wide wheels.
WEAKNESSES: Specsavers?
