Spinners and arena walls

[ewan]

It wasnt bolts that came off I dont think Gary - as I understand it the solid blade snapped.

Theres few MAJOR differences between that arena and what the FRA have set for safety guidlines for the UK arenas. The FRA have set a 1m seperation zone which often helps lowering the impact of debris on the outer screens. Also, the method that the polycarbonate is mounted in those pictures is very very bad. The polycarb has aboslubtly no flex, and so instead of obsorbing the impact it just shatters. This is the exact reason that most the known UK arenas have ALOT of flex over a very large area.

The DRG arena polycarbonate screen isnt even bolted at all. The 12mm thick PC is sandwiched between 2 steel Lprofiles, with a foam protection to avoid scratching and chafing.The whole sheet can flex and move, but even the worst we can do wont push the sheet out of the frame.


And, of course, we dont have such insane spinners as our US fellow roboteers. (oeps, forgettting some of the monsters ,like Supernova or Scorpion)

Holy (bleep)! Id be shaking if those spinners crept into my room at night!

Arent there stronger plastics than Lexan (that are clear, obviously) ?

[maddox]

Nope

[kodster]

Shame. :sad:

Maybe they could make multiple layers of 1cm thick Lexan that can be placed 5cm apart...

Unless its too expensive.

[typhoon_driver]

that would be exceptionally expensive plus it would over complicate the arena construction before an event

[kodster]

Bugger.

Any other ideas?

[grant_ploughbot]

do as above stated by myself and mario. Have lots of FLEX!!!!
Im not at all suprised that polycarb shattered

[jamesb]

or use transparent aluminum.....



(any trekkie will get that one)
