Robots Live! and Robot Wars (Roaming Robots) tour the UK. Well, they tour England but sometimes get lost and go to Swansea and Edinburgh.

That depends on your location.
The cheapest way would probably be a feather weight wedge. I would recommend:
Drive: A pair of Robochallenge 12volt drill motors. I'm not from the UK, but this seems to be the most popular drive motor.
Wheels: Again, Robochallenge wheels, which are pre-made with the threads required.
ESC: A pair of BotBitz 85amp EScheaps. If you're feeling daring, you could hack the ESCs your self, but it's risky.
Radio: Hobbyking HK-T6A. Decent radio, but I would recommend the link cable to add mixing and the likes.
Battery: A pair of 7.2volt NIMH sticks. Lithium batteries are preferred, but they burst into flame if miss handled
Charger: Turnigy ACCUCELL-6. Needs a power supply, but you can use a computer supply if crafty.

Just a note playzooki I wouldn't 100% trust ribbs, most of his stuff he takes straight from ask aaron, which is kind of outdated.

I'm using my own judgement here, usually I hit bulls-eyes, but when I miss, I somehow hit the car behind me.

here:

http://titantechindustries.com/kits.html

personally, i wouldn't use slot aluminum and t-nuts for a frame. too much potential to shift and for stuff to slide out.

that charger sucks. i had one and it charges way too slowly for my liking.

i love the vextrollers. i should have run them in robo-rooter at botblast.


the fingertech viper kit is similar with differences being they give you tinyesc's, set it up to run off a 9v battery and have a pre-built frame that may or may not be useful depending on what you want to do.

kitbots.com has some nice 3lb kits. the "weta" kits consistently win events.

ESC: A pair of BotBitz 85amp EScheaps. If you're feeling daring, you could hack the ESCs your self, but it's risky. (if you know how to program, go for it. heres a link to how otherwise just buy it from botbitz.-skbt)
Radio: Hobbyking HK-T6A. Decent radio, but I would recommend the link cable to add mixing and the likes.
Battery: A pair of 7.2volt NIMH sticks. Lithium batteries are preferred, but they burst into flame if miss handled
Charger: Turnigy ACCUCELL-6. Needs a power supply, but you can use a computer supply if crafty. (you just need to  buy one on ebay that matches the input specs- skbt)

in a 30lb wedge, i would run at 5s lipo or 18v nimh and 4" or 5" wheels with 4 drill motor drive. anything less will be slow for a wedge.

Drill motor drive is always a good starting point but if you want to spend a bit more money get some gimson GR02's, botbitz85's have been proven to be good esc's for the price and be able to stand up to most things thrown at them, I can't vouch for the charger ribbs suggested but I have an Imax B6 to charge the lipo in minor tom but it can also do nihms, battery wise 12v will run the drills fine but if you want a but more punch to your motors you can go 18v which does make them run faster but increase the likelihood of stripping gears. HDPE is a good material to work with, it's easy to work, relatively cheap and quite tough if you get it thick enough. If you plan on going to the champs though wear resistant steel like hardox is the armour of choice there because of the spinners.

They're 100 grams overweight, if you can figure out how to lighten them, then yes.

They are allowed as the weight and size limit aren't enforced at RR events so anything of reasonable size and weight are allowed.

What kind of metal do you guys use for antweight spinner weapons? I was toying with the idea of a custom made one from Kitbots but if I could just get a piece of metal cut and stuff it'd probably be cheaper.

A single piece of machined steel, or an aluminum main body with steel impactors.

4130 or 4140. robo-rooter's disk is .25" 4140. if i was designing an disk or bar antweight i'd do .125" thick 4140. if i was doing a drum, i'd do something like the kitbots beater with 3/8" 7075 and 10-24 capscrew teeth.

also its cheaper to build 3lb robots

it costs $40 for two 1000rpm motors and two vextrollers  vs the $110 for two tinyesc's and sparks
