Only 15 robots entered so far: were halfway there !
Real RW Royal Rumble will be up soon
have a look at issue 2-4 in official robot wars magazine in the news section.
to scott: what name did you expect from a russian guy, andreivich? :proud:
Ivan, for those of us who dont read the magasine, could you quote the feature on them please?

Master Blue
Weight: 120 kg
Shape: A box, its base is square, and its height is about half the lengt/width, its top is curved.
Dimensions: 1,35x1,00x0,40 m
Speed: 18mph
Ground Clearance: 0mm
Armour: 4mm Titanium
Wheels: 4 inner wheels
Power: 24V battery and motors
Weapon: On top of the curved top is a double headed axe, Terrorhurtz-style, but alot more deadly, it can sweep back and forward 5 times a second and comes down with a power of 300 Kilogram. At the front of the robot are two sharp spikes of 5 cm each, able to perforate 1 mm of titanium with no problem, but especially able to hold the opponent in front to let my axe do his job.

Strengths: Very violent, very destructive
Weaknesses: Cant do much against a full body spinner
Tactics: SMASH, SMASH, SMASH!!! while I hold my opponent stuck in front of me with my spikes, Ill probably try to take out my opponents weapon first, by piercing his pnumatics for example
Ill post my second entry when I think of one :)
So you want a second robot from me. I did do something other than go-kart testing this week in Wales :proud:
Meet Project Old Age
Team Name - Team New Age, testing department
The Team - Dave is the driver, Steve controls the engine, and Emma is the flipper operator
Robot€™s Name - Project Old Age
Concept of Robot - The concept behind Old Age is steam, using several boilers and a walking system, to give torque to drive.
Mass - See Below
Weapons - The robot has a flipper, powered from one of the outtakes from the main boiler, giving about 205 kg flipper power using a standard ex-hydraulic ram. There is a front scoop which is powered by a single invertible linear ram, to lift the front off the ground to act as a brake. Never trust the handbrake, use the front bucket. The scoop can also be flipped up with the flipper, and can lift up without the flipper.
Self-righter - The main self righting method is a €œCentre of Mass Srimech€ which means that the robot can not land upside down without the robot being unbalanced. If the robot is flipped onto the top, the exposed steam ram will walk the robot around, slowly but very stylist.
Boiler - There are 10 little boilers, each in the shape of a cone, at an angle. Why cones, due to my research a cone boils water the quickest. The boilers are heated by a express water heating element, designed for use in the steam cars. Picture 2 shows the way the boilers are aligned, the pipes are heavy duty pipes which can restand temperatures up to 500 degree.
Walking Method - So how do I get the steam from the boilers to power the legs I hear you ask? The boilers are aligned so that 1 give the steam to the flipper storage, 1 gives power to the generator to generate electricity to power up the elements, 4 of the boilers are controlled to give power to the front pack, and the final 4 are used for the rear pack of legs.
So how do the legs work? - Taking one set of legs on there own, the pipes are all pumped into a 10 litre storage tank, heated at 101 degree to keep the steam in it€™s form. Inside the tanks are a set of steam wheels which turn in total via belts a shaft which is though the centre of the tank, held in place by a seal. The other end of this shaft is a flywheel, connected to a rod via a tooth system (see picture 5). The end of this rod is connected to another flywheel, which is exposed at the top and used to do the dance if the robot lands onto it€™s top. From this flywheel, another clogged rod (flywheel has teeth, and the top of the rod has teeth at the top) comes down into a trick duel way differential (one side can spin clockwise, then the other side can turn anti-clockwise) to power a shaft with cams on it to lift and walk 3 legs either side. See picture 4.
12 legs in total? - There are 12 legs in total, but 6 are always on the ground because of the cam system. However to give support, a part of the chassis is on the ground which is lifted up with the legs. This may or may not get passed as a proper walking system, but it is more of a walker than Anarchy.
So, you have explained the walking system, what about the flipper? - The flipper has a 5 litre storage tank, which is like the main walking tanks, heated. Inside the tank is a shaft to turn a flywheel, which using teeth (see picture 5), the shaft opens the inside of the tank to let about 125 ml of steam out at a time and pressurises it to send it through the ram, connected directly to the flipper hinge. The steam is re-routed back into the tank, but the excess is used to power a horn.
Velocity - The speed of the robot is a mighty constant 5m/s (about 12 mph).
Turning Circle - It uses a simple skid-steer system and can turn on the spot, but not that quickly (5 seconds to do a complete 180).
Ground Clearance - At the front, the flipper comes to the ground with a 5cm extension plate giving zero, underneath the skirts is a clearance of 15mm. The skirts reduce this to 1mm. The front scoop is fixed to the front underneath the flipper itself, and it stays to the ground when lifting the robot up in the air or the reverse it lifts up to lift skirts.
Skirts - As stated in the ground clearance, there are side and rear skirts, sprung at the top to stop non-wedges getting underneath the 15mm clearance. The skirts will not do a thing with wedges, but it can always self-right.
Armour - The sides are 2mm aircraft grade aluminium over a layer of 10mm compacted chalk over 3mm steel, bolted onto the steel €œladder€ chassis. Spinners will remove the top armour, but thanks to the compacted chalk, will never get far because the chalk will be flaked off. Compacted chalk to loose chalk is in a ratio of 1:3, the aluminium is bolted though the chalk onto the chassis. Underneath the aluminium is a thin layer of carbon, glued onto 5mm of pine. The aluminium will be ripped of to knock off the titanium teeth on the disc, which it will scatter against the pine (metal disc designed to cut metal vs. a piece of wood). If the disc survives the carbon and wood armour, the chalk is next and if there is any gaps between the disc and the main body, the chalk will get stuck in there. In addition the loose chalk is useful for robots with a low ride height or go-kart wheels. Being a go-kart driver, I know the worst thing to get on the wheels is chalk, as it sticks and doesn€™t come off.
Colour - The robot is white.
Safety - Safety is an issue with steam, but because of the chalk the heat will not be able to get out. To stop ignition, there is a pressure release value on all of the holding tanks to stop the pressure getting above 200 psi. The steam is vented via pipes into a cold holding tank to turn it back into water to be pumped into the main water tank. In the pits, there is a cover to be bolted onto the flywheels and a stand to sit the robot onto. The boilers can be removed within 20 minutes.
So How Much Water? - In total, it has 15 kg of water on board, but thanks to the ruling that states water is a consumable and isn€™t measured when the robot is weighed, it doesn€™t come into the weight limit.
Times - It takes about 15 seconds to get the pressure up enough to walk, and 52 seconds to get the tanks filled and working efficiently. As the robot has to walk into the arena, it is run for 1 minute before walking into the arena.
Shape - The shape is a box with a narrow top, see picture 1.
Masses -
The total mass is spilt into these areas
€ Walking system (2 holding tanks, rods, flywheels, legs etc) - 58 kg
€ Boilers (10, plus all piping and heating elements) - 36 kg
€ Water Tank (Plus water) - 24kg
€ Weapons (Flipper, ram, holding tank, values etc) - 26 kg
€ Electrics (Servos, remote control system etc) - 13 kg
€ Chassis (Armour, bolts, welds, connecting poles etc) - 49 kg
€ Horn - 2 kg
€ Other (Generator, batteries, pressure values etc) - 6 kg
€ Holding for power link - 1 kg
Total - 215 kg, but as the 15 kg of water doesn€™t count, 200 kg on the dot.
Summary - I would like to thank, Michael Hunt for the steam system, George Sheppard for the walking system, Chris Rombach for the flipper, Richard Marriot for the armour and off course Kate for the main idea. When did you see the steam robot?
Strengths - Hmm can never break down; will always self-right, unless out of the arena.
Weakness - Unusual power source, high ground clearance, can€™t self-right once over the arena fence.
Youre not allowed to enter walking robots. I already tried.
[Also, Walkers get the extra 20kg for batteries like everyone else (Heavyweight walkers are normally 200kg, so 20kg is added for batteries or gas, depending on your choice) ]
its be shufflers that not allowed.
Sorry I aint been here to reply a while...
Chris: Banks is not a technical word, AFAIK. Shuffling feet/plates are however, that how I see it anyway. Banks are still stuiff you get money from IMO.
