How could I Improve pt 2

[leorcc]

The ram doesn't have to be vertical.

To make it the most effective you do.

The ram is now a 100mm bore 150mm stroke ram.

To make it the most effective you do.

I believe it's more to do with pivot points and length between pivots that make it more effective.



Ram lays flat and arcs up and forward. Only on 600psi and it threw 13.6kg further then any feather I've ever seen.

[leorcc]

Have you seen Kenny's feather flow?

[gravity]

that looks complicated.
so bound to go wrong.

And to get back to my original question:

Would using Armox in this way be workable?

[gravity]

yes, it would work, but it would be quite hard to get the robot under 100kg, and also space inside the robot is an issue.

Could you give a design picture, top bottom ? Cause I'd like to see how you would fit 2 co2 canisters (40cm long, 14cm diameter), 2 magmotors and a 17cm diameter ram inside such a compact space.

Also, no buffertank ? So filling the ram straight from the co2 canisters ? If yes, then bad idea

[corsair_lightning]

Not really. I'm rather pathetic at drawing, and would have no idea how to draw it. But anyways, revised stats:

Bandwagon 3 (Active)
Weight: 100kg
Shape: It's a box with wedges on all sides ala Storm II. Gone is the scoop on the front.
Colour: Gold with chrome chassis and black skirts.
Dimensions: 90cm x 85cm x 25cm
Drive: 2x 24v S28-150 Magmotors, powered by 2 3000mAh NiCad Battlepacks.
Locomotion: A pair of Goodyear foam-filled Go-Kart tyres.
Armour: Here's where the armour gets a bit unusual: Like Killobite Hex, the chassis(3.25mm hardox) is part of the armour, however in between the chassis bars are plates of 4mm Armox that I have slid into slots in the hardox frame.
Speed: 15mph
Ground Clearance: 0mm at front, and at sides and back due to 3mm titanium skirts. 5mm without skirts.
Turning Circle: 0m
Weapon: The weapon is a rear-hinged flipper, powered by a 2.5kg Co2 tank at 750psi(with a 750g buffer tank) via a 100mm bore 200mm stroke ram. This should give my flipper enough power to flip about 1600kg. The flipper's ram is positioned to give me a 2:1 reduction, giving me 800kg of flipping force at the tip of the flipper.
Srimech: The flipper.
Strengths: Very tough, powerful flipper, etc.
Weaknesses: Made by a novice.
Bio: After reading a page about Armox on the SSAB website, I decided to use it in a vapour. Seeing as it's very tough against explosions, it should survive in the arena...
Win/Loss Ratio: N/A

I can see a couple of things wrong there:

1) I don't think S28-150 Magmotors are powerful enough for heavyweights. You might get away with it if you don't do any pushing. But it's better to be safe than sorry, so I'd try and get some S28-400's in there.

2) I don't know a lot about pneumatics but I'm 99% sure there is so such thing as a 750g buffer tank. If one does exist, I would assume that it wouldn't be adequate for this purpose.

Is there a particular reason you're using Armox? Does it hold any advantages over using Hardox, Titanium etc.? Or are you using it just for the sake of using it? I'd probably increase the ground clearance a bit as well... Other than that it doesn't look too bad.

1: S28-150s are used by many a US Heavyweight(albeit mainly the lesser-known ones).

2: I took the idea from Jack Orr's CrOoKeD eVo's stats:

Weapon: A Co2 full pressure flipper at 750psi with 1 110mm ram,and a 2kg bottle and a 750g buffer tank.

3: To quote something Leo said earlier in this thread about Armox:

You can't drill it, you can't weld it, the only thing you could do is clamp it in something, but that thing would probably get ripped off before the plate gets a scratch.

Apparently, Armox is very tough, perfect for a robot...
