Hello everyone,
I am trying for find a suitable battery for a given set of mechanical structure+motors(DC and servo), and ask some pieces of advice.
Sorry for the length of this message, I am a bit lost, and have a lot to explain before asking precise questions.
I am going to use 2 IG42E

And 2 servo motors HerkuleX DRS-0101 Smart Robot Servo
see:http://www.robotshop.com/productinfo.aspx?pc=RB-Das-05&lang=en-US
The mechanical structure is small car of 14-20 pounds (60cm by 30 by 30 basically) , with 4 wheels of 5 inches (the proportions of a standard SUV, which a scale of 1:6 or 1:7). the two rear wheels are actuated by the IG42Es,
and the whole thing should go up to 10km/h.
I have several questions.
I need to determine which battery would be fine for this configuration.
Could you please tell me if a LiPo Rechargeable Battery 11.1V 5500mAH would be ok? for one or two motors?
see http://cytron.com.my/viewProduct.php?pc ... %205500mAH
And if yes, how long do you think it will last? (or how to do the calculations, because I don't know how).
I would like to control two IG42E with this battery(or two) through the MD10C Enhanced 10Amp DC Motor Driver (or two),
is it possible? see http://www.cytron.com.my/viewProduct.php?pcode=MD10C
I would command the motors by using an arduino board (I still have to determine which one, the UNO or the Mega)for the logic commands.
The arduino will also be linked to its own battery (or maybe I could use the same battery for everything?)
and to two other shields, one to control the servo motors (these two servos are intended to turn the two front wheels with respect to the two vertical axes passing trough the center of gravity of the wheels) and the other is an xbee shield to communicate with my laptop ( to do simple manoeuvres, thanks to a video game set of driving wheel and pedal connected by USB to my laptop) It is a remote controlled little car, long story short.
I would like the whole thing to be as simple as possible, to code some simple algorithms in the arduino board,
which would receive inputs from my laptop, calculate commands to send to the motors, thanks to formulas that I will implement in the arduino board.
Besides, if you have any piece of advice concerning anything, from the choice of arduino, to anything about any component I should use, please tell me.
Concerning electronics, I have never used anything before , so I might be missing something quite basic.
I would like the whole thing to be as simple as possible.
thank a lot to those who will answer,
