Is hardox absolutely necessary??

As a reference, this is what Carbide did to the mild steel on Nuts: https://www.facebook.com/nutsrobotic...type=3&theater

We're useing 3mm Mild steel.. But do have 12mm round bar inside the bot for extra strength.. I can't afford Hardox but will see how Griffalo goes. Can always make it smaller and add a thicker mm steel

I have a load of hardox you can have FOC your local to me some come take it away Clevedon

No offence intended, but I think 8mm angled is a bit overboard.

Last rites bent 1" thick hardox equivalent at Robogames

8mm is definitely not overboard lol

To be fair, it did take several enormous smashes from the most destructive spinner in the game to bend that stuff. The total kinetic energy used to bend that panel must've been immense. And again, nobody has the weight for 8mm all over. Whoops! and Sewer Snake are only armoured at the front as far as I know. Whoops! even has the advantage of having no active weapon mechanism, which wouldn't be allowed on TV.

That said, I do understand that 8mm isn't overboard for more heavily-armoured sections. But I still think it is if your entire HW shell is made up of it.

With the right design 8mm will take anything really, it depends on the design and how its supported/mounted and if it is angled just as much as the thickness IMO

Its reached the point where you can't stop the spinners from cutting through your armour or bending your whole robot out of shape. The way forward now IMO is shock mounting your armour to lower the peak forces exerted by any weapons; see Beta as a great example.
Of course that has its own drawbacks and issues but even if you take an impact that lasts 0.1 seconds and turn it into 0.2 seconds you have still halved the peak force.

Regarding the question, I'd be tempted to have multiple armour pieces cut in Mild if you can't afford Hardox and just keep changing the panels. You only need it to last 3 minutes; that's still a LONG time with Carbide, but after that you can fix any damage. Just make sure you have spares!

To be honest, my thoughts towards armouring up against spinners are now more towards hardox frame and lots of HDPE+air gap - no matter how hard they hit, if they can't gouge through the armour enough to hit anything important then you're pretty much set.

Not sure on any examples in heavyweights off the top of my head, but that's definitely a good tactic in Featherweights and below. shock mounting definitely helps things out too if you can't do the above.
