thanks

Re: Axes and hardox

I think you will find it depends on how well the armour is supported beneath, what angle to the horizontal the armour is and how much flexibility the armour has been allowed,

For Saint Thor has bent it over the fights it has had. and now and again I have to get the big hammer and do a Quasimodo
ringing session on the drive here at home (the bells they made me deaf you know .)
That is because the axe from Thor hits at an angle on the upper section of the Saint meaning it has point rather than blade contact being close to the top plate there is not much flexibility for the armour so it bends even under the rubber outer skin!! the Saint is made from 3mm ARM steel this is similar to Hardox400.

Cherub is a more standard robot and against Thor the front 3mm ARM did bend Not a lot but enough, the rear section is made from 5mm steel I don't know what the hardness is as the supplier was not sure himself. But it is the same stuff they make the hull of nuclear subs.This did not bend under the Thor hammer and showed only the slightest of dents.

I have found HDPE to be very good as armour, Seraph is made of the stuff, and when NST hit the wheel of Seraph in the UK champs it ejected itself out of the arena but Seraph worked fine. I have 20mm lid on Saint and has proved to be far better than 5mm steel armour and half the weight, the wheels on Saint are 12mm HDPE and they have lasted 2 years now.

Hope that's given you something to think about

Re: Axes and hardox

thanks craig, yeah i'd definatly go for hardox sides to give it some good strength as for the top lids problem is i could use some 20mm hdpe and be good against axes but then tiberius is gonna go right through it so im gonna have to put my thinking cap on lol

could mabye do interchangable lids or something or if theres weight have hardox covered by hdpe on the top areas

thanks for the help

Re: Axes and hardox

Tiberius is only one robot that only sometimes fights, if you ask the guys not to put a hole in your robot they usually don't.
My experience of kan Opener is the pincers only go through about 50-60mm tops then the resistance of the HDPE equals
the crushing force so if you have an air gap between the armour and the soft stuff you should be OK. remember the shape of the Tiberius beak,
means it can only nibble the edges.
The bottom line this game is paper, rock scissors you will not make the perfect robot.

Re: Axes and hardox

Just a question here, since we're on axes (don't want to make another thread). What's the limit to how heavy an axe should be? If it was too heavy, then with a long arm the robot would be flung about like crazy. Of course, you can minimize this by having an extremely short arm, correct? Would a really heavy weighted hammer axe swung close to a robot's body be an actual viable weapon?

Re: Axes and hardox

Hey there

As far as i know there is no limit on axe weight (probably wrong) but to be on the safe side, at least 10-25kg should do
the trick and not fly around like a nutter

Hope this helps
