Building my first robot /W Design Idea.

Hey, there guys I'm new to this fantastic helping forum (I only signed up today). I have been wanting to build a robot for quiet some time now but I just havn't had the advice, money or time to do so... I am a real newby this being my first ever build. I have a little experience in Nitro rc cars and electric also I have had an indoor flyer (Helicopter)

Here are some of my design Ideas:

Please comment and advise me :) (I Know my drawing and designing is bad so Shh :P)

I estimated that the components from Robochallenge would set me back about £230 (Without armour, Baseplate weapon etc)

These parts including:

A battle switch,
3 12v drill motors (one for weapon but I may upgradto a 24v)
Verticale and horizontal mounts for the motors,
100mm blue wheels W/ nuts,
The DX5e with reciever,
Red and Black Meter long wires,
A quick charger.

What else am I missing out? and have I got the corret essential components listed? And how much would the baseplate and armour be? (description on diagram)


Thanks
-Jay

You forgot batteries :P
Oh and get rid of the [img] tags from the original post so people can just click onto them and see.

Yeah I forgot about that :) Should I get the one from Robochallenge or invest in a better brand? (I Probally wont have the components till christmas :()

You want something a bit more serious than a drill motor - ESPECIALLY a geared down drill motor which won't spin very fast at all - to power a spinning weapon.

If you aren't going into the massive can of worms that is brushless (ludicrously high power to weight ratio, but expensive and prone to regular failures), something like a car fan motor, couple of overvolted speed 900s, or if you're feeling a bit better off a couple of overvolted 18v dewalt motors or such like will give you a creditable weapon.

That's not getting into the really nuts stuff like multi-kilowatt brushless or magmotor setups which the really scary spinners are using, though that will set you back a LOT of money so I wouldn't recommend it for a first robot.

*has massively disregarded that suggestion on berzerker!*

look on

and u forgot a speed controller (or motor controller :roll: ( its a thing that controls the speed of the moters)

u will need 3 speed controllers or 1 dual (i would go with sabertooth dual) and 1 single speed controller

but i am NOT AN EXPERT

Thanks guys, What batterys should I get?

nimh are probably your best bet as a first option. Car racing packs usually do the job fine and are relatively cheap and difficult to screw up.

Re the mag on a feather spinner, only two feathers have, vortex and hornet and it was a pain fitting the weight in a featherweight so I ended up with a motor that weighed the same as the disc i was using in hornet.

Actually Gary LS3/Poop-a-Scoop has one as well.

To start with a spinner is a risky move, it may well be worth your while to attend one of our events first and get some information direct from the sources. Whereabouts are you from Jay ?

Hmm, I really not sure what Weapons motor to get any suggestions. (My budget is roghly £300 I could maybe push but I will be building it over a couple of months)

You realise that if you have a spinner on your robot you can only enter 2 events a year

I live in harlow which is about 30 minutes from london.

It's got nothing to do where you live it's only that theres one arena in the country that can take spinners (you have a drum spinner on the front of your robot by the looks of it) and that arena only does 2 events in the year.

Only two events? Well... what about an axe? Or even maybe a pneumatic driven spike?

an axe is good or you can have a flipper/lifter but a pneumatic driven spike, I dont know...

For a cheap but effective spinner motor, a pair of Speed 900 motors work well. For an example of what they do, look up some 2009 videos of Drumroll.

Axes are a bit easier to make and can be used at all events around the country. Pneumatic spikes are largely ineffective against modern armour.

I asked about where you live because even with only 2 spinner-capable events per year, you would be well advised to attend an event nearby (or indeed any event) to get some information and examples directly from the sources.

Having looked it up, I would say your 2 nearest events would be Brentwood in Essex and Maidstone in Kent. Maidstone is coming up in November, details can be found on the Roaming Robots website.

I wouldn't mind doing a flipper or even a pneumatic hammer/axe but apparently there hard to make? But I don't know cos' i have zero experience ;) So Pointers please ;D?

Thank you david :)

get yourself to an event, you'll learn more than you ever could on the forum

I will be appearing at either the Brentwood one or the maidstone one :) I hope to see some of you there?

sweet. Personally I generally am only at the spinner only events run by robochallenge simply because spinners are the only weapon type that interests me but you will be able to pick up a lot of info etc from any event. See you at a spinner event sometime soon

Yeah see you at one :)
