Base Plate Materials

nope, the only uk full combat events are robochallenge ones.

if you are having to use 30mm HDPE then I would suggest a redesign of the bot.

If I went with the Ti I would save enough weight to go from 20mm to 30mm of HDPE on all sides so it would make it much harder for a spinner to get through to touch the base itself...

1mm Ti= 4.5mm HDPE

When is the next full featherweight combat event? Is it the Robots live in september?

For us on the main land it's may 6th. In Antwerp.

Hannibalito 3 uses a 10mm belt, and 20mm strips welded on reinforcing strips on the back corners.

I am using 20 mm out of choice, the HDPE absorbed everything inertia xl could throw at it and, though it got ripped off cos of my poor attachment methods, withstood a full on NST hit as well. The extra 10mm would allow me to bolt rather than screw the base to the sides making it both stronger and easier to replace if damaged.

The design is very strong at the rear due to all of the interlocking and a joining parts, the front needs work to prevent pieces from being ripped away by spinners. The issue was the nylon did not provide a suitable material to bolt to as it was to brittle, Ti woill definatley work but the alternative is to turn to HDPE as a base

The link above should explain what UHMWPE is sorry for the confusion


Here is a fight with Saint (the one with the big green wheels) the robot has had the same wheels for over 2 years now and they are still fine and only 12mm thick!!

3mm Hardox is on Explosion's base, and (apart from one corner), it survived a full match with NST and is still perfectly flat.

Can you even get 3mm Hardox? I contacted 6 companies for my disc and the minimum they did was 10mm-15mm.

Nope , you never could buy it. What most people call 3mm is actualy 1/8 3.2mm.
And SSAB isn't making that anymore. (I suggest you readthis SSAB file)Even worse, even when they made it, it was rare, and over here, only available in full sheet. 6*2.5m

For a disk, I would say 10mm is a nice thickness.

Not technically

The 'Hardox' that we're using on the feathers isn't actually Hardox, but an exact copy from another company and therefore without the 'Hardox' brand. But they did 3mm. We bought a metre square sheet of (I think) John Bell back in 2007, and it's the same stuff he's armoured Dantomkia with.
