Anybody who watched the latest series must have been impressed with the sheer strength of some of the designs and the way they were mostly knocked to pieces by one "robot" with a huge spinner on it.
I wonder whether it would be practicable to cover your bot in a thick layer of sticky filamenty stuff that would tangle up with the rotor and stop it spinning?
A spinning disk has the means of storing a lot of energy, such that their use maybe unfair and perhaps encourage their use too much.
Steel wire might be a better bet! That assumes it would get caught up by something on the spinning disk and then be a consumable.
Like chainsaw PPE you mean? ;-)

Kevlar fibre is already used in similar way in some applications , Clothing for people operating a chainsaw is one, The clothing is not as some think tough enough to resist being cut, what happens is if the blade penetrates the Kevlar filling it is dragged into the mechanism and hopefully jams it to halt .
As for such an application in robot wars it would seem so obvious perhaps there are construction rules that limit what can be done so the contests remain a spectacle for viewing.

Well who cares. I'm not sure what the point of this series is. the earlier ones were a bit naff, this one seems to have pushed naffness to a new depth. Brian
Last night on the American version called battle bots that's on Spike TV one contestant used a net to stop a spinner but the contest was stopped as entanglement devices are not allowed
Entanglement devices are prohibited by the construction rules. A robot fitted with anything like that will forfeit the fight.
I was thinking that hardened steel rollers, as used to prevent some lock hasps from being sawn through, might provide protection.
The commentary has always been naff but given that it's predominantly a visual spectacle, are you best qualified to comment Brian?

And on that, there are different grades (classes?) that are based on the chainsaw 'blade' (bar) length and chain speed and role (in a tree or on the ground etc).
Like I believe they can't use any projectile weapon (flame, acid, rockets, bullets etc).
I think that as the level of robots entered into the event generally improve, the 'fun' for the spectators may diminish.
It is like with F1 where they are constantly having to limit and constrain certain things to try to stop it becoming (even more?) boring and processional (as you might see if you watch any of the very restricted saloon class racing with 4 cars side by side into every corner!). ;-)
I think I preferred some of the earlier Robot Wars series where most entrants did actually get ripped (or fall) to bits every heat. ;-)
As with F1, most can marvel at the technology but it's not particularly interesting / fun to watch if one make / driver / machine constantly beats the rest.

Or a better retainer for the 'safety link' as that falling out seems to kill more bots than receiving damage as such?
I appreciate it has to be easy to remove and possibly 'readily accessible but few rally cars and others fitted with an isolator key seem to have any issues?

It has to be possible to fit it while standing outside the fighting area and leaning over a barrier. It can have a cover, provided it can be opened without tools, which might help with reliability.

Assuming they are using the Fighting Robot Association rules, projectiles are permitted provided that they have a tether that can stop it at full speed and that is not more than 2.5m long.
Thanks, I sorta had the thought of that in the back of my mind.
I guess part of the reason I've never seen such used is the limited affect of something that can be stopped by a tether etc (if a tether can stop it reliably, so would most armor).

Oh. I was reading some of the rules around the link in the link you posted previously. Will all the rules it's surprising they can actually get any robot to comply!
And invertible robots have to have one on both sides! ;-(

"In the sixth season of Battlebots in 2015, the American broadcast network ABC failed to explicitly exclude entanglement devices, which resulted in a series of controversial decisions".
Presumably they've added that rule back for 2016, as per the previous paragraph.
IIRC you aren't allowed a projectile and a detachable filament would be a projectile. Its not going to help if the filament doesn't detach as it immobilises your robot too. The best you could probably do is try and arrange the filament to pull the other robot onto a ramp so they are immobilised but you aren't.
The rules bar that kind of device as it makes the battles less exciting.
I have visions of a harpoon, to drag the opponent into range of your weapon.
Wet wipes are amazingly tough. DAMHIK.
