Id love to help out but I am having a serious blond moment here.

Would it be possible to build a vapour walker (200kg in weight) with 4 legs, each using two short, low pressure pneumatic rams 9one for up/down movement, one for left/right movement), or would it just require so much gas it would be overweight?

Ive toyed with that idea myself and although in theory it would work it was too complex for my liking. Too many valves, too many variables.

However, with a 5kg tank and small enough double acting rams like 16mm @ 10 bars for instance, yes it could work. And it would beyond a shadow of a doubt be a true walker.

Dont ask me how the steering would work though, I completely threw my towel in the ring when I came to that stage.

It may take a while, but Im going to give this a try, since its only vapours. Basically, no one nick my idea while I try and get it to work!

Nice to know there is some originality still around.

Dont worry, Liam, I dont do shufflers/walkers anymore. The last one I did was in the 2002 era, Junkyard Maw. Yall remember how well it did it in PTT3 pinball. And it actually won a round. What possessed Steve to have it win something, I dont know.

Just re-checked my notes, 16mm was radius, not diameter. Told you I had a blond moment.

Robot Name: The Subjugator
Shape: Box with skirts all the way around
Weight: 200kg
Length: 90cm
Width: 90cm
Height: 35cm
Motivation/Drive: 4 x hardox legs with vulkalon rubber feet, they are each actuated by two 10 bar 16mm pneumatic rams from a 5kg tank, they are not visible as they are internal
Armour: 5mm titanium on top, 5mm titanium (then space for the legs) and 4mm hardox on sides and 1mm polypropylene base
Weaponry: A Son of Whyachi style tri-bar made of steel, but instead of the hammers it has tungsten claws that each weigh 11kg, and with the bars it weighs a total of 45kg. It is spun by a LEM-200 at 48v (Kj output and spin up temporarily unconfirmed)
Speed: ???
Turning Circle: In the centre of the robot€™s base armour there is a 20cm x 20cm circular section that extends to below the robot via another 10 bar ram, but this one is 400mm and takes the gas from its own 1.1kg bottle, once on the ground the circular piece of armour rotates in the direction which I want the robot to go via a Bosch 750 watt motor at 12v
Ground Clearance: 20mm all round, protected by 7mm titanium torsion sprung skirts, held together at the corner s by 5mm hardox hinges
Srimech: None, but it is hard to get under
Colour: Silver cage, black bodywork and the name in white on the front, sides and back
Strengths: Twice the weight of most opponents
Weaknesses: No srimech

If not 16mm, what would you suggest?

Oh, sorry, 16mm radius means 32mm diameter, my bad.

Mkay, is the turning mechanism feasible? Also what speeds do you think it could reach?

its absolutely feasible to turn that way, but not very quick. What I am more worried about is what that huge triangle spinning frame does while you wobble across the floor.

About the speed I cant make any predictions since that involves length of leg and the swing angle.

Maybe Ill change the weapon, I have other evil plans

Wouldnt linear actuators be better than co2 pistons?

[leorcc]

How could I Improve pt 2

In what way?

The use of actuators vs pneumatics is always a careful deliberation.

In terms of simplicity, actuators would be better.

However in terms of speed, weight, and oddly enough durability the pneumatic ram would be in an advantage.

Both methods are not wrong. In fact the most famous true walker I know, Mechadon, uses actuators. However in this application I would prefer to use co2 because of speed and weight.

Do you think I could get about 6-8mph?
