King of the Kill build diary

aka ITT: bad generic robot(s)

I've decided to build a fw, already built a terrible ant and a battle antz kit.
My parts list is not completed, here is what i have so far:
gimson gr02s
hdpe 12 x 1000 x 500mm
blue robochallenge wheels
Fly-sky FS-t4b transmitter (already have)

I aim to get this done for the northern tour and build over the summer holidays

here is a basic cad of the design:

RoboChallenge don't sell their wheels anymore. Try Banebots wheels on the Technobots site.

thanks

updated list of parts:
gimson gr02s £62.60 for 2
hdpe 12 x 1000 x 500mm £37.30 direct plastics
banebots 98x20mm £12.16 for 2 wheels http://www.technobotsonline.com/bane...-shore-30.html
mount - £3.00 for 2http://www.gimsonrobotics.co.uk/fixing-kit_GR02_screw-washer.html
battery - 12v nimh £25.95 http://www.componentshop.co.uk/12v-3...tery-pack.html
charger "Turnigy accucel 6 " http://www.ebay.co.uk/itm/TURNIGY-AC...item3ce3046d4c
dont worry about the prices and links, i copied and pasted this of a list i made :)

I'd go for a 4s lipo instead of the nimh, lighter, more powerful and probably cheaper. If you're using the Accucell it charges lipo anyway

yeah i dont trust myself with lipos

4S or 3S is fine. Here is a 3S lipo for the a little less: http://www.ebay.co.uk/itm/Gens-Ace-2...item2a3faec8ae

Here are two 4S options http://www.ebay.co.uk/itm/Gens-Ace-1...item27e5f07f02

Treated right they aren't dangerous, you just have to make sure they are well protected, charged correctly and not over discharged.

well protected in the robot? i highly doubt i can do that after my last ant.

Just so it's secure and isn't in any danger of being hit or knocked loose, in a box with foam is fine and cheap/easy.

(This robot is Nyx btw)

ok, thanks

I have that exact same 12V nihm and can vouch for its awesome ness!!

Anybody know where i can find a removable link for sale? And where can i find a suitable led?

LEDs you can find at any good hobby store, but ask someone other than me about links. Mine was a complete bodge.

Make your own removable link, get a deans connector and solder a loop of wire across the two pins, as for led's I got mine from eBay but technobots is also good

I bought my leds, deans and xt60 connectors online via eBay.

Rs components for led, hobbyking for deans connectors

hey does this parts list look okay?

Looks good, you won't need the BEC though, the BotBitz 30A has one built in

Why not a LiPo battery? It will save you some weight and you'll have a decent self balancing charger to go along with it.

because
1)i dont trust myself with lipos
2)nimhs are easier to use, because of the safety stuff

fair enough
