first robot

i am trying to make my first small rc robot, but i dont know where to start.
i have read some threads on the forum and seen that chordless drills seem to be popular here, so il think il use some motors from those, but what else do i need an what will it cost?

my dads an electrician so i think il have most the tools i need and he should be able to help me with anything with electrics.

Hi there, first let me say I am new myself and am only just ordering parts for my first robot. But I have recently used this forum for exactly your purpose (see http://www.fightingrobots.co.uk/foru...p?f=164&t=3000)

However I am now fairly confident in giving you this parts list.

Transmitter and reciever
Motors
Batteries
Speed Controller
Building material

On the cost front it seems as you can spend as little or as much as you like, you will probably be looking at £250 upwards. However note the more you spend the better it will be.

thanks im going to search around and find some parts.
i might not have £250 but i guess i can buy it bit by bit, but xmas is coming up so i should get some money the :)

£250 is probably a little extreme. The transmitter and reciever will be the priciest purchase, but once you have that you can use it on any robot prokect you decide to take on. For a simple featherweight drive set up, you're probably talking about £100 without the transmitter. It's a good idea to get it in bits though, you can always start building even if you don't have the parts yet.
Good luck.

i allready have a transmitter so i wont need to spend any money on that, il start buying my parts after Christmas.

...might be a bit of a silly question to ask but what frequency transmitter is it? If it's 2.4ghz or 40mhz you're fine, but if it's a model aircraft leftover and on 35mhz or a 27mhz set from R/C cars I wouldn't reccommend using them, since the former frequency is banned for all non-flying vehicles and the latter is quite prone to interference.

not sure what frequency it is and it doest seem to be written on it anywhere.
all i know about the transmitter is that its from a rc car my dad had. do you think it will be any good?

Does it have a crystal? If so check it and that will tell you the frequency.

oh its the crystal :P
i think its 255, thats whats written on it.

Unfortunately I have no idea what that means exactly, someone else will have to help you there.
