Thats it, Rev II will have to enter, Ive got to show half the newbies how to build a robot with proper parts! Its noob busting time!

Name: Revolutionary II
Motivation: Wheels
Speed: 8MPH (Translational speed)
Weight: 109.9kg
Height: 170mm
Length: 1000mm
Width: 1000mm
Weapon: The weapon is just the same as Revolutionary, but this time, it has the legendary and nearly outlawed Gas Turbine implemented. To fit the 19kg 65HP 20000rpm Gas Turbine into the weight limit, the design went through a large weight loss design switching from Aluminium Boron Carbide which is light and strong to a heavier Hardox 400 which is stronger, and used less over the whole robot. 3 large portions have been removed and are air gaps to save weight. The total weight of the drive in the last version of Revolutionary was close to 45kg (32kg in motors, plus the rest in gears and wheels) The new version has a 42kg drive set up with over 20kg into the titanium mod 3 gears for the twin stage planetary gearbox which is then into a single stage bevel gear box. This is then transmitted to the drive wheels via magnetic clutches/brake which control the speed of the robots wheels to enable it to translate around the arena like the previous version. The whole robot revolves around at 2000rpm and produces easily over 120 kilojoules. Spin up time is limited to 2 seconds as the magnetic clutches are eased on to save the gearing from over torque as the turbine opens up to full power start up.
Armour/Chassis: 5mm & 10mm Hardox 400 ware-plating
Notes: Will easily attract the Anti-Turbine enthusiasts, invertible, first ever petrol powered translational spinner! Extra 10kg is in the fuel canisters. It should easily run for 20mins since its carring around over 400L of compressed oxy-acetylene fuel ITs got a bit more armour around the canisters too(not like anything would go through 10mm Hardox)

Lets kick bot!

Guy with the unpronouncable name, what exactly is an atomic battery?

[knightrous]

FRA Royal Robot Rumble: 30 enter, 1 leaves

Something futuristic, like Lead Argon batteries (Fame from Short Circuit 2 Moive) which cannot be used in robot combat because of free flowing liquids

Sorry Aaron. The weapon is now powered by 2 Eteks running at 48v. It is now geared down 2:1 so it spins at 3400RPM.

[knightrous]

FRA Royal Robot Rumble: 30 enter, 1 leaves

Eteks are nominal 48v motors, they do 3400rpm at 48v so your going to have a 1700rpm weapon right now

So you want a second robot from me. I did do something other than go-kart testing this week in Wales

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.

FRA Royal Robot Rumble: 30 enter, 1 leaves

[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.
