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
I think you mean the Series 1 Rex Garrod machine Recyclops.
Wat that angle predrilled? Or did you drill all those holes yourself?
what are the measurements for for you frame tom?
it looks very nice and stable! nice work:)
alex
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 :p 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
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.
try this for HDPE sheets

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.
