Martyns Robot Wars Series 5

Cheeky boy system has 12 legs i think, itll probably fll voer or strumble with only 8 so there

Also I think with such minimal power in your mobility you wont be able to move at all. You expecting Two standard wheelchair motors, at 12 volts power the legs to move. to work. I use magmotors at 36 to get archangel moving, that poer had to go through all the cams in the legs and i doubt what your suggestign would be adequate.

Let me just do a quick weight breakdown, and this is the non techie here

engine - 40 kg
shell - 20kg
chassis - 74 kg
claws: there are six of which so, as for exampel the mortis axe blade weights 3kg, assuming its half the weight of that we get 9kg for puny blades
a starter motor, lets be generous and say there weight 3kg
same again for the wheelchair motors

That 152kg, which means your trying to fit batteries, the legs of the machines, the skirts and the fuel tank into 48kg. Considerign scuttle b2 (anarchy without the armour or weapons) weights 100 that just aint gonna happen, especially seeign as the design of the cheeky boy system requires large feet.

I would say that the shell wil break up upon reaching max velocity. Mainly because Dave is stretching 20kg worth of metal around a 1.6m diameter. Thats almost only 2mm steel ! For that size and speed, I would like to see a minimum of 75kg weight spent into the shell before I would believe it will survive.

The engine, is possible, but Ive never heard of any Rotax motors running turbo/charger on the intakes, is this some new, uncommon racing mod? Also 4litres of fuel is a bucket load for that size of motor. That would run it for several hours! I would expect something like that being used with a Gas Turbine!

The walking system, I wont get started on that, but I know the Anarchy system can be done with four legs per side with chains, sprockets, legs and structure around them for under 25kg each side with no problems (This includes PERM080 drive motors)

survive the hits by the almightily MDU

Okay, enough of this... MDU is gone.. its in the past, stop damn posting it in your stats!(This goes for everyone else too)

Well Im going back into my workshop to play with my omnibot. BYE

But he would need 50 kg in total for the legs and parts that go with it, but then he doesnt have any weight for the large and heavy fuel tank, the skrits or the batteries.

Additionally even for a full body spinner hes using almost 75% of his weight in his weapon, in contrast tengu and archangel only have around 50.

*Wonders why the american system is growing and the british system is dying*

Jihad was only a joky entry, t was 30 months old, so thats why its so shit. Another change of entry, replace Jihad with The Linear Mover which is an idea I had, stats when I can be asked to draw it up, you might have a lovely picture of it as well

Oh for any applicable deities sake!

STOP DOOMSAYING YOU TWERP!

Martyns Robot Wars Series 5

The Linear Mover

Mass - I don€™t know(with any luck within 200 kg )
Weapons - A 6-bar spinner (weighing 26 kg) (Bar sits on top) with the ends bent downwards to stop robots getting underneath. The bar is powered by a Lem 130 at 48 volts, and spins to about 3000 rpm. The bar has suspension on it, so it can hit hard objects without breaking
Srimech - It has a large pole on the top to self-right
Velocity - 02(TWO) mph!!!
Ground clearance - At lowest, with the legs up, the base is on the ground, with the legs down it is 1cm.
Skirts - Nah, the legs go up.
Wheel Type - 8 legs with a linear actuator in the middle of the legs motion, so is the leg. When the actuator retracts, the leg goes forwards, and when the actuator is at the end of its movement, the leg is going backwards. It€™s a bit like a train (Ta for Mr Frank). There is a 2nd linear actuator on each leg to lift it up, mainly to allow the first actuator to go back without moving.
Motors - No Thanks, I will pass on having drive motors this time
Batteries - Enough to survive 6 minutes of fighting action.
Body Shape - Cut-Off cone, with Ziggo style Srimech bar
Armour - 4mm titanium cone, with steel inner section/base.
Colour - The bar is red

Summary - It€™s a walker designed with those anti-walkers in mind, if the system doesn€™t class as a proper walker, nothing will. Thanks to Frank for suggestions.
Strengths - Weapon, 360 degree attack, Srimech, Most of weight is in base
Weaknesses - Crap at turning, crap speed, not the best to drive.

Ingore those stats please mr martyn:

The Linear Mover

Mass - I don€™t know (with any luck within 200 kg )

Weapons - A spinning semi-shell (aka Typhoon), powered by a Lem 200 at 48 volts. The shell weighs in the region off 45 kg and takes ~ 2 seconds to spin up fully to 950 rpm, with the gearing from the motor. The shell has blades, 4 on the bottom level (1mm from base) and 4, 5cm up. The blades up a bit are longer so that it hits with 2 blades. The shell itself has rubber suspension to take

Srimech - It has a large pole on the top to self-right; it€™s bent at the end

Velocity - Two mph!!!

Ground clearance - At lowest, with the legs up, the base is on the ground, with the legs down it is 1cm, but it changes when walking.

Skirts - Nah, it€™s variable ground clearance, so skirts would get in the way.

Wheel Type - 8 legs with a linear actuator in the middle of the legs motion, so is the leg. When the actuator retracts, the leg goes forwards, and when the actuator is at the end of its movement, the leg is going backwards. It€™s a bit like a train (Ta for Mr Frank). There is a 2nd linear actuator on each leg to lift it up, mainly to allow the first actuator to go back without moving the robot back. There is a back-up system in which the entire leg system can drop down to lift the base off the ground to move.

Motors - No Thanks, I will pass on having drive motors this time

Batteries - Enough to survive 6 minutes of fighting action.

Body Shape - Cut-Off cone, with Ziggo style Srimech bar

Armour -6mm titanium cone. Steel chassis, aluminium legs.

Colour - The bar is red

Summary - It€™s a walker designed with those anti-walkers in mind, if the system doesn€™t class as a proper walker, nothing will. Thanks to Frank for suggestions.
Strengths - Weapon, 360 degree attack, Srimech, Most of weight is in base.
Weaknesses - Crap at turning, crap speed, not the best to drive

Yep, Im that bored.

Just get rid of your walkers. If you cant design a walker we dont have a problem with, doesnt it say something?

Ill have a look at this new one.

[knightrous]

Martyns Robot Wars Series 5

Build it and Ill believe it.

The reason the UK vapourbots are dieing is because people like you, Dave, are constantly trying to pass off cannon fodder as entries.

Damn I miss the days of SpinVerter 3, VGer and The Robot That Wasnt There.

If this walker isnt a true walker in the terms of martyn, then what is? I designed it with the Fra walking rules in mind, so no cams, no chains, no gears.

[knightrous]

Martyns Robot Wars Series 5

It is a true walker. According to the rules, Ill give you that, it looks almost the same as the Jim Struts/Miss Struts walking mech.

The whole cam situation only applies to people mounting off centred wheels (CAMS) and calling them walkers. One of Christian Carlbergs robots was like this and was quickly banned.

V-gers still around, so 1 out of 3 aint bad.

...Actually, yes it is. Its only 33%

[swiss_tony]

%33.3 and a third, Frank.

Tony, stop being so picky

Thats whats it suppose to be, an old-school walker which are slow, crap to turn and normally have limited runs. If I wanted a fast walker, I would just use the shuffler system called Anarchy. Besides like I been asking, what other weapon are you suppose to put on a 2 mph walker to give it some hope...

... a flipper?
