I have some video's of Andrew riding Vertex around my front yard from RoboWars 1 with fire and smoke coming from the HPC (Human powered Controllers)..

556 Meg though, they're in uncompressed AVI format. Perhaps a CD if you cant find your media of it ?

sorry about the other day i was in a bit of a bad mood and also with the fuel tank i was going to pivot it caus if the bot gets flipped and its upside down the petrol will leak out of the breather on the lid and i just thought it would be good to use an ice caus were getting one for free

If you used an i/c engine you would have to prove to the scrutineer that the fuel tank can not leak in any position .so you would have to use a tank with special one way valve that lets the air in but does not let the fuel out ..Most modern whipper snipers and chain saws have these fitted as standard .

Answering your question, Wilko, in Battlebots, walkers get a weight bonus because of their weight, but tracked robots don't.

and i thought we might be able to build somthing like that caus we've got ALOT of machinery and one of the guys in my team his dad is a certified machanic so he's picked up alot of skill from his dad and also could u use a few sprokets just with a chain around it for tracks??

im guessing this is your first robot and no one round you has buildt one like this.
there is a reason no one uses track bots it's because they offer no useful bonus in "normal" battle conditions you would probly get the same effectiveness as a 4 wheel bot with the front wheels driven by a v belt off the back wheels (seperate pully system needed)

as for your sprocket idea i don't really see how it would work, chain links offer little to nil traction on most smooth surfaces. (try attaching smooth stainless to the bottom of your shoes and go for a run around the arena, take video camera )

also haveing a mechanic on hand isn't needed but it can help (mine used to work on everthing from minis up) just a general idea of how certain stuff will work together and a broad mind will work just as well.

Yet another dans-data link for Track Afficiondo's.. (I'm more into Rotors myself

I thought i had some info and good pics that would be of interest...

Would YOU pay 16500 for a timingbelt driven robot?
Well... i think it can get alway with it seeing as its not about to face any robot wanting to rip it to bits...

hey this looks a time to cash in if we start makeing robots that have tank treads and with spy cameras on top and recievers the parts would cost about $500-2000+ we could sell them muhahahahahahahah

has any one heard of using LOTS of hinges and bolting them together and using them for tank tracks. also how hard is it to get ur hands on some chainsaw chain (for a weapon)

Hinges . . . dunno, but I dont think they would work that great and would be pretty heavy. For the chainsaw chain, im pretty sure bunnings would have it, but if not, just go down to your nearest mowing / power tool place, they'll have it for sure.

flea markets has chainsaw chain cheap as well.

whats the point of a hinge system, with solid steel its not gunna have any traction which is kinda the point of tracks

Hmm I think I would have a different opinion there: the whole point of tracks is to not get bogged in soft soil snow mud sand etc. Tracked vehicles are normally massively heavy; but because the tracks cover an equally huge area the ground loading is less than a wheeled vehicle so they don’t sink in.
