As far as I knew, 12, 24, 36, 48, and 60 volts were/are the norms. Anything above or in-between is weird or overkill. :P

Presenting; the next machine in the No Objections line, containing another of my crackpot ideas. (Im open to name ideas; was going to call it No Apologies before I realised it was taken)

WEIGHT: 110kgs
DIMENSIONS: 150 x 135 x 15 cm
SHAPE: A low dome type shape; the actual dome is 135cm diameter; to my knowledge the largest vapour out there
COLOUR: Yellow, with a yellow and black striped lifter with red forks, and stylised black arrowheads on each side. The spinner rim is metal-coloured with red teeth
DRIVE: 2 S28-400 Magmotors running at 24v from 6 NiCad packs, driving two inner custom built 5cm wide/90cm long Vulkalon/Kevlar belt tracks; however these are designed such that the two idler sprockets (either side of the drive sprocket) are raised 5mm off the ground, so normally (due to weight distribution) the robot only rests on the bit of track below the drive sprockets, giving it excellent maneuvrability; however when pushed (or hitting someone with the spinner) the robot rocks slightly and a larger part of the track comes into contact with the ground, giving it more grip and helping it stay in place. (as always, if my powers of description are inadequate I shall draw a diagram)
SPEED: 14mph average, 20mph max
GROUND CLEARANCE: 7mm all around; the blades reach about 1mm below this
ARMOUR: 5mm aluminium baseplate, with a 7mm HDPE curved top panel supported from a Hardox chassis with 3mm Ti/Vanadium alloy beneath.
WEAPONS: Main weapon is the 12mm thick outer Hardox ring spinner, which makes up the bottom 2cm or so of the body of the robot. This outer ring is driven by two S28-400 Magmotors run at 24v, but with the timing on the motors adjusted so they run faster in one direction, making the ring faster. It weighs about 20kgs and has four S7 hardened tool steel teeth on it, extending about 5cm out, and it spins at 2000rpm giving out about 50kj per hit.
However, the effect of this can be increased if the robot itself spins on the spot, which increases the energy to around 80kj.
The other weapon is the Hardox-reinforced lifting arm, which runs from a 1 tonne linear actuator and runs the entire length of the robot, hinged at the rear, but also extends out over the front of the spinner before touching the ground, allowing the blades of the spinner to pass beneath it when down. The lifter can lift about 200kgs easily at the tip and extends to almost vertical in about two seconds.
SRIMECH: The lifter
NOTES: Internal components shockproofed to protect it from its own and other peoples spinner hits.
STRENGTHS: Large area of attack, maneuvrable, versatile, good pusher as well as damaging
WEAKNESSES: Large area to attack; vulnerable to axes

Do your nit-pickyest worst

Call it No Regrets

[kodster]

How Could I Improve...

Nah, call it Unobjectionable

Seriously, I cant see much wrong with it other than maybe the ring being a little overweight. Cut it down to about 8mm Hardox and itll be fine.

Paul: I am not naming any of my machines after a Robbie Williams song, sorry :P

Kody: Right...I was more worried about my tracks idea being non-functional for some reason, or people noticing I BSed the kilojoule numbers
Would 8mm be strong enough for high-energy spinning applications?

[kodster]

How Could I Improve...

Id say so.

[joey_picus]

How Could I Improve...

Right...*goes over to Zlaying Every Day board*

Incidentally, I messed around on Google for a bit, and the new name for it is No Exceptions

[kodster]

How Could I Improve...

Haha.

But Paul still hasnt done anything reasonable with Nitro-Gene 5.0, and Id like to see him do that. :P

[paulc]

How Could I Improve...

I have done something reasonable to Nitro-Gene - I had to start all over again, and Ive reduced weight, not added too much on, and Ive also reinforced the chassis with the rubber shock-proofing, made it taller to make the dimensions realistic and gone back to the 6 wheel set-out to improve power and traction in a straight line, and Ive also maximised grip in turning.

And Ive also improved MeCannibal so its no longer got power unheard-of-except-with-tourneys-with-MDU-in-them :wink:

By the way Joey, I didnt know that No Regrets was a song by Robbie Williams, as it wasnt on my Robbie Williams album :blush:

No, Paul, the armour is the main issue. Thin it down to 3.25mm Hardox, remove two of the LEM130s, or look to titanium, but theres no way your going to fit all that into 100kg.

EDIT: Also the motors will make you overweight: not by themselves, but because of the batteries. I know what Im talking about. Take for instance 4 LEM130s @ 36v. Those require about 3 NiCad Battlepacks each, and those weigh about 1.8kg. So you are looking at about 20kg of batteries alone, and combined with the motors, thats 30kg. Combine that with your 6mm Hardox armour (density is akin that of steel, which is 7750kg/m cubed) and youre overweight as it is.

Kody: finally someone who understands why battery stats are important.

[kodster]

Well, Leo, considering with no batteries Id have a classic 80kg heavyweight without the ability to move...

Is this vapour OK?

Liam: LINKING FAIL

[kodster]

Expand the dimensions a little.

And yeah, the link is phail. :P
