hi Tom.
Drop me an email
There is nothing I can do for you as far as new robot builds go, until May at the earliest, but after then I may be able to help.
I do sell robot components aswell as complete machines, just get in touch, and also check out http://www.technobots.co.ukwww.technobots.co.uk for the biggest choice of bits I know of.
I did have a ready to fight featherweight on ebay recently for £300, I still have it if you are interested?
cheers

Thank you for the help you have all given me already.
Right i have decided to try build a featherweight robot but i need some help selecting components. im trying to build it abit on the cheap side but not so cheap that its full of crappy components. would have loved to find eveything all ready to run all in one place and it just needs fixing into a chassis and connecting some radio gear but its impossible i looked everywhere. anyways here are a few things i need abit of help with.
what drive Motors and gearboxes are the best to use and whats the best way to go about having 4 drive wheels if i decide to do that?
what sort of speed controller would i need?
what is the best battery to go for if i do have it with 2 or 4 drive wheels?
I may also be going for a vertical spinning weapon approx 120 dia, so what kind of motor will i need for that?
then its just the radio gear. if i got a 4ch futaba kit that should do me just fine right?
if you guys have any links that my help or links to ebay where i can find the stuff i need that would be very helpful. can you think of anything else i might need?

Cheers.

started making a test frame today to sit stuff in and check it works while im building my bot. made of 100% scrap metal of the best quality. i wanted it super light weight because it doesnt need to be strong as it will get scrapped soon as my new frame is built so i went abit crazy drilling 14mm and 18mm holes all over the frame. seems alot of time wasted for somthing that will get scpapped when i build my new frame. i dont know why i went with a wedge shape for this test frame tho took about a whole 1 hour to make omg drilling took 90% of that time up welded it up in about 2 mins, didnt even check 1 corner for square but its nearly square i cant believe it.
(my bots not called biohazard i took pics on my fone and the fones name is biohazard and it saves all my pics and vids with biohazard(number).)

BTW was there a bot called recycler or recyclers revenge? i was offered a bot years ago but i didnt have cash then but i cant remember the name of it.

Looking good there Tom, looks like your a pretty competant fabricator if that only took you an hour and desnt look at all shabby!
If your looking for somewhere to get all your components to get your robot moving then contact James at Robo Challenge, he sells drill motors, motor mounts, wheels, batteries, speedo controllers and other bits you might need.
you can contact him by e-mail at james@robochallenge.co.uk

Good Luck

yeah i drilled it all myself thats y the holes are abit wonch hole to the line after i drilled it and guessed the center on the angle. its only 25x25x3 angle and 25x3 flat so it took no time with a 6.5 drill then just went through with a rotor broach. the longest flats from back to front took only a few mins to drill. i didnt make it to a drawing i just used what ever length off cuts i could find in the scrap bin.i only had to cut 3 pieces to length and then just cut the angles at the front and top of the wedge thats it. could probs make one in about 4 hours if i did it properly and to a drawing but the off cuts were there and i had nothing else to do (appart from working)so i knocked it up. it looks better in the pics and it doesnt look too good in them its only small its about 400mm long bout 250mm wide bout 140mm high and the wedge is around 280mm long which leaves the top 140mm or so long. well about that its not having to hold a battery or wheels as its just my test frome i wanted it light as possible with the material i had. them sizes are rough as im at home now and the frame is at work but those sizes will be within 5mm of what i said. might eventually put an rc car inside it and cover it in some realy thin aluminium just so i can let sombody fight it against the one im building.

with this spinning weapon you are going for, will this be in this frame or a better one

my first bot was 540mm by 280mm wide, bit smaller than mine

no this just my test frame so i can check it all works befor i put it into the frame im building soon. im making it just a rectangle ram bot then hope to get a vertical spinning wheel on front. abit like tornado just not as good but ill probs go with aluminium for my armor to keep weight down on it cos i dont wanna drill a load of holes incase i put a spinning disk on it and it twists as soon as i hit somthing

[typhoon_driver]

Tom I would perhaps look at 4 or 5mm hdpe for armour. Light as anything and it deforms then returns to its original shape when hit. A very interesting material! Plus its cheaper than aluminium.

can anyone give me a list of components i need and whats best to use with what. i need a list of everything to make a featherweight robot with a spinning weapon. id like a motor gearbox combo like the grimson robotics ones.

buy a pair of ten quid drills from focus, argos, or whereever (this means you must learn to modify and strip them, giving you important knowledge and experience)

Ewan sells suitable wheels.

Get 2 good speed controllers, you cannot go wrong with robot power scorpion XL, supplied by me (and now in stock) or the electronize range from technobots. The 15A cpu version of the electronize is my suggestion if you do not want to invest in a scorpion.

batteries are a subject often discussed, but the basics are, drill batteries will do if you want something basic, but i suggest some nimh race packs as a huge improvement, either from me, technobots, or your local hobby shop (ebay?)

spinner....... build the robot first, fight it a few times, get a feel for the shows, then ask again. spinners are not for first time builders in my opinion, as they are as likely to write off your own machine as you opponents.

hope this helps.
