On Another safety note you would have to store the l/nitrogen away from danger i wouldnt like it to be spilt in the pits .. your venting of the co2 was scary enough .... ive played about with liquid nitrogen a little when i was younger on a dairy farm i dont like the idea of frozen fingersor toes if its spilt into someones shoes.. as for the bots i doubt a spinning saw would freeze from a stream of the stuff unles it was from a fire hose most of it would be flung of with centrifical force and its own expansion as it turns to a gas the same would possibly aply to wheels unles you are planing to pick the bots up and dump them in a bucket of the stuff lol ...

This is bound to cause a rot, but I'm waiting to see it work. If it works, time to get serious

EDIT: I just thought of something that this bot is breaking. Your using liquid Nitrogen as an " untethered projectile "

BIAIBI....

further thinking
N2 will displace air, your body dosent detect a lack of oxygen you detect too much Co2, you wont realise your sufficating, you'll fairly quickly become disorientated then sleepy then you laydown and die. so yeah if you gass off a signifigant ammount of Ln2 you will want much ventilation (change the atmosphere in the arena roughly 2x a minute and i'd say have 2 change overs before allowing people in. in addition you must ventilate from the bottom as the vapour given off from the Ln2 will be cold so it will want to sit near the floor. in this regard CO2 is probbly less dangerous, you will recognise you "cant breathe" and will more than likeley do something about it, Ln2 you dont get that "i need air" feeling)

As to it actually working.
most steels and the like arent going to change all that much over a moderate temperature range so you will have to do alot of cooling to have much effect. an nobody is going to let you keep their robot dunked for the 30seconds it'll take to cool off signifigantly.
meantime they will be trying to kill you.
people seem to forget this when they are designing robots, the other guy isnt going to be sitting there letting you hurt them
they are going to be killing you.

part B of that.
ok so its brittle, now what?
gearbox is well insulated, even dunked in Ln2 its still going to take 20-40s before it becomes cold enough to worry anything.
the steel sides on cobra are now "brittle" uhhh sfw, unless you have some kick ass spinner to take advantage of that it wont do anything.

LMAO you suck so bad

OK, OK,.. 1 Point to Philip for suckering the rest of us so well..

Look at the volume of posts you generated in a short time.. you sure engaged everyones imagination well..

And Jake just goes 5 steps too fair into technicallity land

I know that land.. its not hard to encourage a techie aware person to go there..

I recall a heated conversation we had in a repairs department once over the exact spectrum of radiation being emitted by an item and whether it was a simple linear function of current/temperature or whether the molecular structure of the radiating electrdode material would have a significant impact on the the emission parameters and would have to be carefully measured before such a sweeping statement of its suitability as a raditation source for a particular job of illumination we needed could be made.

Yes, we suddenly reaslised we were about to come to blows over what sort of light comes from a light globe. and one of those moments where everyone suddenly stops and thinks "Either we were just behaving in some incredibly intelligent technical way without realising it..... or we were all being complete wankers" decends upon you..

Its a phenomenen that happens me quite often in my life.. So what I'm saying I understand Jake launching off into Techno-Land at the drop of an electron. Been there, Done that. Its Fun

Anyway, as Arthur C Clarke put it..
"The only way to discover the limits of the possible.. is to venture a little way beyond them.. into the realms of the impossible".

He Also said "Any sufficiently Advanced Technology is Indistinguishable from Magic",, which is where my business and team gets its name from..

Too late for all my NIB magnets, Phil - they shattered from shame at being hoaxed so thoroughly

While we talked about oxegen deprivation, I just watched a video from Robogames, where the Bounty Hunter guy released his almost full tank of CO2 after a quick win. I wonder how he felt after almost dissapearing in the resulting fog cloud?

Would you know if it was particularly humid at Robogames? My CO2 bottle doesn't cause clouds when it is dumped.

No idea really, but Bounty Hunter vented LOTS of 'something' every time it lifted so it could be they have a design problem where they get liquid CO2 in the ram, which I hear is a bad thing.

Have a look at the vids on the Team Cosmos site, the fight with Steel Pirhana is a classic lifter tactics lesson

I checked and the event is near the bay in San Francisco, so it could be quite humid...
