Dave, yeah I'm planning on making one too. Been umm-ing and err-ing as to what design to go for and what parts to use for a while, but just recently decided I'm going to try a kilobot version of a featherweight design I've had kicking about in my head for ages but that has never been built (Snakebite) so that means I'm going for a vertical crusher :)
seeing a crusher would be cool.
Theres no real size limit. Just some of the things like the pit etc ill need to see what size most robots end up being. Oh pit will go up and down, Might have pit release mounted so that it cant move about on the arena walls but can be pressed so instead of pit being opened by a person its the robots that actually open it. Dunno yet tho, Was thinking about having somthing similar to that spinning floor section on robot wars arena floor. Then make it so a hub can be bolted to it then have a disk or bar that bolts to that so theres a fixed spinner in the arena, Will be activated for maybe 30 secs after a robot hits a button. Depends if people are bothered about getting there robots smashed. Somthing like a 2kg spinning bar hitting a 1.3kg robot could cause a bit of damage.
i think Ive seen an American kilobot arena with a similar floor spinner..
2kg might be a bit much.. i think theirs is basically 4 stanley knife blades bolted to a spinning hub.
Crusher would be abit lame in 1.3kg i reckon but a pneumatic flipper could be awesome.. I was looking at doing that, just not sure what id use as a reservoir for the gas... might make a flippy one later.
Yeah I probably should have clarified that; although I'm calling it a crusher, I'm not expecting much beyond a firm grip, maybe a little bit of penetration (giggidy) especially as you could get some pretty strong top armour for not much weight.
It's going to be a threaded rod on a motor to power it, don't know what motor yet but I'll play around with some options and see how it goes.
I was never a fan of the disc of doom (or whatever it was called) in the RW arena, but a spinning disc coming up from the floor could be interesting. It would certainly bring an element of control back to proceedings, as roboteers would have to make sure their driving was up to scratch to avoid unnecessary damage but as Dave says, 2kg might be a bit too much. If I remember rightly, Hornet's disc weighs 1.8kg and look at what that can do at speed to featherweights nevermind kilobots :lol:
ill have a 1mm carbon fiber lid Jamie I'm sure you'll get through that! if not ill put cardboard on it lol.
hows about kill saws instead tom? Ive got some horizontal milling cutters you could use, spin em up with something and have them shoot out the floor battlebots style?
You allowing magnets tom? since your floor's steel...
Ye have magnets if you want.
In between fights you would want to be able to activate or reset the pit from outside the arena. Probably during fights as well.Quote:

Anyone making any progress with theirs?
After coming across some motors that might be good for this class - if a bit slow - I might knock one together from spare bits and take it to an event at some point...are there any plans for when you might be able to use the arena for the first time?
Such a shame I no longer live in the UK. I've got some wood (don't laugh!) hanging around which could make the perfect armour and plenty of old motors and RC cars. I'm pretty sure, what with my young 14 year old mind, that I'll be able to make something decent. I've been building all sorts of crap since I was 5 or so so this should be childs *cough* play.
Not like I'd be able to compete anyway... If only my school were more interested in anything at all! :rofl:
I've convinced a classmate who also builds things and sticks 24v batteries onto the tiny little motor jobbies you get in phones to make them vibrate for the hell of it. I can have my own little mini-competition ;)
Looking forward to seeing some of the bots being built... I want to see if they look as bad as my chunk of wood!
