Running 24V 150W Gold Motors on 12V

hehe , grant you read my mind, i was just about to ask about that kinds of wheels to use. Yeah i dont have the facilities to do that :sad: but you have mail :)

ok a few minor points i just thought of, whats the best way of mounting the motors ? and connecting them, as wont they just be a loose wire as i had to remove them from a drill ? As im connecting 2 motors in parallel to each of my speed controllers, what kind of wiring/connectors should i use.

and the nominal 5V receiver supply used to power the speed controller, whats this, do i need to do anything to convert my 12V battery output to 5V ? im sitting thinking no, as i need my 12V to get to my motors to power them but i want to check

thanks again

I have sent you an e-mail with prices, would you like to give me a call as soon as possible and we can sort something out, including any other problems you may have.

Good luck

what size are the wheels you supply?
id be interested in some.

Hi Mark

The Blue wheels are avalible in 63mm, 75mm, 100mm, 125mm and 150mm. there are larger but these are the most popular. We are also pushing a new range of wheel which is maufactured exclusivly for Robo-Challenge. These are 100mm diameter.

Drill kits will be avalible very soon. these will include a high quality lazer cut steel drill mount and modified wheels with the threads melted in.

for more information email us at robostore@RoboChallenge.co.uk

ok, heres my parts list so far minus the chassis/armour materials

1 x Futuba Skysports 4 Channel Transmitter with Receiver/Servos £105.58
2 x Electronize 30A Speed Controller £79.80
4 x 12V Cordless Drill (Motor, Gearbox, Battery,Charger) £59.96
4 x 100mm Black Wheel £20.00
4 x Motor Bracket £24.00
1 x Mixer £12.99
Misc - cables/connectors etc £5.00

Grand Total of £307.33 without any chassis or armour materials, and i havnt even budgeted for a weapon yet !!! is it always this expensive or is it just the cost of the transmitter thats making it seem so huge ?

Most importantly, is my list complete, am i missing anything ?

it is always that expensive.

You can do it for cheaper by getting parts second hand or through sponsorship.

O and you will need to add a removable link onto that list, you can get one off of stu for £5 if you ask nicely :)

Yep, they can very often cost many hundreds more like in my case:sad: The transmitter is the main bulk of the buy which makes any size robot feel expensive, even antweights. You may not need a mixer though, all depends on if thats the way you prefer to drive. personally i dont like the things, but most people do.
Also, it may be worth your while if you speak to a few companies or send some e-mails round for some form of sponsorship as this will help you alot in the future. It means that any ideas you may have for improving your robot can have a hope in hell of ever being produced lol.

best of luck

So what will happen if i dont have a mixer, i thought i need a mixer for skid style steering ?

If you dont have a mixer, it will be very hard to control the robot on 1 stick (which about 90% of roboteers do) or you can put the RIGHT motor on (off top of head) on channel 2 and the LEFT motor on hmm channel 3 (left vertical stick) and you can control it like a Tank. Means you need to use both sticks to control the robot. Both sticks up for forwards, both back for backwards, the left stick forwards and the right stick down(backwards) to turn right - and vis versa.

A mixer takes both channels and then enables you to control forwards and backwards on one channel and left and right on another channel. Like i said most people use channels 1 and 2 (which is the right stick on a TX) to contorl a robot (Seems easiest and uses only one thumb to operate means u can use left hand to control weapons etc) or some people put forwards and backwards on the left stick and right and left on the right stick. This is because most RC Cars are controlled like that and their used to it.

Then some strange people like Scoprion put forwards and backwards on the RIGHT stick and left and right on the LEFT stick. very annoying indeed, but its whatever suits the driver. Some people use bloody wheel TXs like Ian L from Razer, but drives the machine like part of his body, George F drives Chaos 2 using just the right stick like most roboteers, and he drives that again very very well. Its whatever the driver prefers.

But newbies do prefer using a mixer and controlling the robot all on the RIGHT stick. Its prob about 90% of roboteers fav way and also my personal way.

Wow Essay over. If you spot any spelling mistakes i dont care, typing it very fast as i gota go out. You get the picture :proud:

Mr Stu

i think im gonna go with a mixer then, seems easier
