Go to Post FIRST robots definitely meet many commonly agreed upon definitions of robots. Some will disagree. Good for them. In my opinion, it's not worth arguing over. - Mikell Taylor [more]

Unhappy Servo Compact Design Problems!!!

Hello,

The Links Of The Image That Descrype The Problem, Please See It To Understand My Problem
http://www50.brinkster.com/dominatorii/


I'm not in FIRST competition, And I'm new in robotics, So please be patient with
me, and use a simple words, cause my English is not so good, Thanks.

The Problem:
I'm building my graduate project it's a rover robot that move on 6 wheels as
shown on the above figure, this figure is a basic design for my BlackBot,
as you can see, Wheels number 1,2 and 3 are connected together with Track-1,
while Wheels number 4,5 and 6 are connected together with Track-2,

Each wheels from 6 wheels are connected to its servo motors, So we have 6
Servo here,

Now assume that we want to compact the design of this robot, can we
connect the servo number 1,2 and 3 together in parallel connection, Called Con-1
And connect servo number 4,5 and 6 together in parallel connection, Called Con-2

I think its ok, if we connect the first 3 servo together in parallel so the volt
is constant but the current will distributed on each servo,
For example: if we connect the 3 servo in parallel, and apply 5 volt and 300 mA
to this connection, So each servo will take 5 volt and 100 mA, Cause volt is
constant and the current is variable.

The question is:- Is there a way (Circuit) That deliver to each servo a 5 volt and 300 mA.

If you see the above figure I supposed that I have an 2 amplification circuit that will
amplification the power and signal that came from the main board and distribute
it to each servo, so each servo take 5 volt and 300 mA,

--------

Please if you can help me on design, (I mean a PCB) or any other things that help
me, making it, this will be appreciated, also I need confirmation if this method have disadvantage (Such as I will not control the speed), cause the servos in
any ways will take 300 mA, There are something I don't get it, Can I control the speed of the servo (make it slow down or move fast), and how is this done,
I read many notes about modification of servo and how its work but I'm didn't
get it, So please if any body, can explain it to me more simply, (The reason my English is not so good), This will be appreciated, and please the confirmation on this design and its disadvantage
