Stabbing split mechanism.

I believe they had about 9 tons in the ram and 3 at the tip of the arm. James C is the best person to correct me if im wrong.

[maddox]

If the Razer ram is 4 bore, and the max pressure used 120 bar, they had aboutish 9 tons.

But, if my memory from 2000 doesnt fail me, the Razer ram is only 3 bore. And that computes to 3000 psi for 9 tons of force.

[craig_anto]

Razer ran a Radial piston pump rated at 10,000psi powered by a 6v motorbike starter motor ran at 12v, so i agree it was a powerfull motor, Razer never revealed its gearing ratio which always lead to some sceptisum as to the psi they were producing, when i personally asked Vinny at an event (i think it was Debenham 03) i asked what pressure it ran at he smiled and said 3000 of course, when i asked again he said might be over but they dont check do they

thus leading to my conclusion of them running a higher pressure, i stand by my beleif that they over ran there psi i dont think they ran 10,000psi but i do think they ran higher than 3000

No i have no evidence other than my convo with vinny which is speculative at best but the fact they didnt enter when they intorduced the pressure test and the fact they never told anyone there gear ratio
No its not hard eveidence but i stand by my comment

I think people forget jus how long ive been building robots, no ive not been the TV roboteer of Behemoth or Killerhurtz (if u think back John we met at series 2 filming) Im not some crack pot disgruntled fan im a decade roboteer, i know robots ive spent the best part of my life playing with these machines and being around them ive fought all of the robot wars champions with my previous and current robots so when im told a robot might be bending the rules i beleive them, i remember Adam clark telling me he had a switch to jump from 24-48v (may of been 12v-24v which is more likely) on corpral punishment that mentorn and the crew didnt know about. It was common practice when razer first was built so yes i do still beleive it

Part of the game back then was flouting the rules... Certain robots weighed in at 80kgs without armour, batteries, gas, etc.

I do know that Razer had a nasty bite, but the limiting point was the arm which would bend frequently. They had the producers on their side which made them untouchable anyway.}

Getting back to the original question for a moment I believe with the new armour Hardox at 4mm plus, not many weapons even hydraulic will ever get through to do much damage to another robot. I am working on a linkage that will operate a 12lbs sledgehammer powered by a spring or bungee cord hitting a chisel that will drive into the armour of an opponent€™s robot but I don€™t think for one moment it can manage significant penetration into a material with a brinell hardness of over 400!!!

[maddox]

Tiberius IV went trough 3mm Hardox as if it was butter. 4mm wont pose much more problems either.

On Razers overrun 500W motor. That equals 2 kw. On 12V that is 166A. With an efficiency of 60% at best -series wound motor. That is 800W of heat being pumped in.
What can we do with 1200W. On 3000psi that gives us a flow of 3L/min. On 5000psi the flow lowers to 1.75L/min. And on the theoreticial max of 10 000psi .85l/min
If the piston pump was of the right size and with the right working range, the max flow would be something of 10l/min, and with the theoretical 10 000 psi max pressure. But I doubt Razer ever got over 5000. The arm was know to bend.

Tiberius IV is an awesome machine and its owners certainly know their stuff, With regards to the 3mm hardox event, do you know how far the beak of Tiberius went through, the further it goes the harder it becomes or am I wrong! Were you trying hard to puncture the armour or was it incidental damage. How many times have you tried to break through 4mm Hardox and can you think of another method of puncturing thick armour that dose not require hydraulics. This subject interests me as I feel the more a robot is made impregnable the more the flippers will rule the world!
PS I don€™t mind flippers there great its just I think other robots need to be developed to.

[maddox]

I know exactly how far Tiberious IV went trough the 3mm hardox of the top plate of TAN.
Untill the blunt point met a piece of 10mm hardox. And because Sam backed up.

And yes, Sam does know his stuff.

Storm II is probably the only robot capable to withstand a good crusher. But, the steel inner frame could buckle...

And puncturing the armor isnt needed to KO a robot. 1 lose wire, a chip janked from a PCB, a broken recieer crystal, a battery with a broken connection, a removed removable link, etc etc and you have 1 dead robot.
All perfectly achivable with shock damage, is that by ramming the opponent into the sidewall, launching it up 10 in the air or smashing it up with a 3 kg hammer.
Problem is, shock damage applies to the machines involved.

Also, I know, and have helped building a pneumatic crusher. The Swedish Mithril. With 8 tons, instant power from a 140mm bore 140mm stroke FP ram it demonstrated its power by snapping a steel benchvise in 2. Unfortunatly, the form of the beak/crusher wasnt the best in the world.

[sam_smith]

Thanks, I am pleased that the weapon has lived up to the design intention.

The force required to crush through a plate does usually increase as it gets deeper, but that is entirely down to the tip/arm design and how much metal is being displaced per degree of rotation and how effectively it can cut.

I think there is plenty of scope for an axe to be able to cause damage to heavy armour. Thzs axe is certainly the most powerful in the UK. Given a sharp axe head I recon it would cause fair damage to 3.2mm hardox.

As Mario has mentioned, there are lots of ways in which a knock out can be achieved through shock damage.
