Put your the motor's that are on the same side in parallel to give them full voltage.

Similar to the last diagram but without the servo and regulator shown here:

Looks good! Thanks.
I had my 6 8.4v batteries delivered. They all have Deans connections but I have a couple of problems with this, how do I go about connecting 3 in series for 25.2v and how do I then attach them to the other 3 to give 25.2v at 6600mAh?

The battery charger did not come with a deans converter either so that's going to cost me and extra fiver buying one. It looks like at this rate I won't have it ready for Worthing.

Re: From The Ground Up (Advice Thread)

disconnect the wires, put a positive on one of the deans prong, then the negative to the next positive of a battery and so on till you have one negative left and put it on the other deans prong.

(sorry if it sounds confusing )

Hmmm, I can vaguely understand what you're describing, thanks Matt.

My Robochallenge wheels haven't arrived yet (even though they were meant to arrive on wednesday?) This is the second time products have been delivered late by them, has anyone else had this problem? Due to this I can't weigh out the internals properly as I don't have the wheels, would someone mind weighing out a pair of their 100mm blue wheels for me so that I have an idea of how much weight I have left for structure? Thanks!

It's pretty standard because Grant and James have other large projects on. I believe they are working on a big one for the gadget show atm.

Re: From The Ground Up (Advice Thread)

Fair enough, I'm in pretty urgent need is the trouble as I'm building this week up at my grand fathers, I'll probably just make some cardboard mock ups to deal with it, I just need the weight of the things so I know what weight I have left!

Re: From The Ground Up (Advice Thread)

Sorry for the double post but I can't find the LED+Resistor combos mentioned earlier in this thread, would anybody have some links to them?

Re: From The Ground Up (Advice Thread)

Haha! Thanks a very much! Very helpful. Onwards with the building. I'm taking photos as I go so I'll have a build diary when I get back.

Re: From The Ground Up (Advice Thread)

Aaaah, I forgot about the technobots site, thanks!

The sabertooth 2*25 is confusing me, how exactly do I connect it to the reciever? Do I need to buy plugs seperately or do I configure it in a different way? The instructions on it are rather sparse.

Re: From The Ground Up (Advice Thread)

you need to buy plugs seperatly.
look at the robot market place sabertooth 2x25 to look on how to set it up

[Roland]

Re: From The Ground Up (Advice Thread)

Had a look and found a lead on technobots that looks suitable, ordered it too! Thanks.

Re: From The Ground Up (Advice Thread)

Having trouble with weight, I have 7kg worth left for Chassis, and 100 cm by 300 cm area to fill. How do I go about solving this issue? All materials seem to dense, and I have no idea how to drop the weight of the internals considering they're already as low as they can be.
