It's been legal since they were first thought about, I believe Matty's done it before

Excellent... That'll accelerate my plans to make my robots better...

Re: How could I Improve pt 2

An old, early version of MOAB used a 10Cell 45Amp LiPol battery, which is going back a fair few years now. Was my solution at the time for running 4 x LEM130 and still having weight for decent armor.

Re: How could I Improve pt 2

Hey guys. I have some slightly good news: I recently acquired Alex MacWilliams' Team Targeted bots, and I also got a couple of robots from Nick(Parassyte), including Pickaxe, The Clones that Weren't There, and V'Ger V5.

I'm wondering: What should I do with them?

Re: How could I Improve pt 2

Not ruin them?

Re: How could I Improve pt 2

I haven't. Well, at least not yet. :P

But seriously, what should I do with them?

Re: How could I Improve pt 2

wait until a tournament pops up and enter them maybe?

Re: How could I Improve pt 2

When will that be? When Mechanical Maelstrom 3.0 is created?

No offence, just saying we have a major lack of Major Tournies.

Re: How could I Improve pt 2

Mechanical Maelstrom 3.0 will be created when I'm ready to create it, and you'll just have to be patient. If you've got nowhere to enter them why did you ask for them in the first place? You've got more than enough vapours of your own as it is.

Re: How could I Improve pt 2

I thought it was a good idea when I got them...

But anyways, I have an idea to work them into something...

Either learn to have some patience or expect to hear these kinds of responses, Mark. :P That's all there really is to it.

Re: How could I Improve pt 2

Here goes... probably the nastiest vapourbot design I can possibly think of. Felt I should try and define overkill here :P

Name: The Impenetrable

Weight: 100kg

Shape: Extremely low box with very small anti-wedge skirts - extending only 15mm up the robot's sides to stop them getting mangled by a spinner, while still preventing anyone breaking its traction. The skirts have rubber seals on their inside for reasons which will become obvious later. Looks pretty much like Biohazard

Colour: Black.

Dimensions: 60cm x 45cm x 7.5 cm

Drive: 6 NeuMotors 2230-725 brushless inrunner motors run through custom reduction gearboxes, one per wheel, delivering 30kW continuous (60kW peak) - that's 40/80hp! Each motor only 1.36kg(!), set into aluminium billet heatsinks, and modified with Hall effect sensors for higher starting torque.

Locomotion: 6 wheel drive, magnet wheels to avoid breaking traction.

Power: 37v (10s) 45/90C Lipo packs. All electrical connections are reinforced to avoid impacts causing electrical problems. Each pair of motors is controlled from one custom brushless speed controller, which receives an independent supply from 2 5AH Lipo packs in parallel - weighing 1.3kg apiece. 3 individual receivers are used (they're cheap and light enough) to ensure that no electrical failure can disable more than one out of three pairs of wheels.

Armour: A lot of 6AL-4V Titanium: Front plate 30mm thick, sides and rear 25mm, top 15mm, bottom 5mm. Internal structure is made from Mg alloy plate to keep weight under control while providing stiffness.

Speed: 20/40mph, dual rate control - only turned up flat out while ramming an opponent into the wall or such like.

Ground Clearance: 0 cm

Turning Circle: 0 cm

Weapons: 4 bar flipping arm powered by a 45mm diameter full pressure ram run from 4 small diameter CO2 cylinders holding 500g apiece - not that many flips available, and not the biggest flipper, but thanks to the 4 bar mechanism perfectly capable of throwing an opponent out of the arena - especially combined with the massive ramming performance.

Wait, I'm not finished yet - dual vacuum units powered by brushless outrunner motors! These create a partial vacuum under the robot, adding 300kg of additional downforce and pulling the sharpened anti-wedge skirts firmly against the ground - making it virtually impossible for any flipper or wedge to get underneath. :twisted:

Why not take a page out of the Storm II playbook and use a geared down Neumotor for the arm?

The kind of peak power that a high flow full pressure pneumatic system can deliver - even with a relatively small diameter ram - beats electric lifting arms all hollow. :

Re: How could I Improve pt 2

...exactly how big are these 2230-725 motors, in terms of dimensions? I've never heard of them before. :P
