Servomotor and regulators selection

Hey all

I’m trying to make an in car robotic-like mechanism and I have come up to some difficulties regarding its electronic-electrical components.
First of all I would like to have a servo motor that could hold about 6 kg (and more) and my only power source will be car battery. Due to the high amp of the battery and due to the fact that most servo motors are working in the area of 6V I would like to ask what kind of regulators should I use.
Should I try it with a standard re-chargeable battery (which will recharge from the car’s battery)?
There must be many ways to make such a mechanism but I’m looking for the most reliable one.

Any ideas or guidelines are more than welcomed :wink:

The fact that the car battery has a high current rating,m simply means that it can output lots of current should it be asked to do so, It does not mean that it constantly outputs a large current.

For a servo motor to move 6 kg around, it will need to be extremely powerful and its potential current consumption far exceeds our largest adjustable voltage regulator: RB-Dim-28

Depending on you mechanical setup you will either need a servomotor with a power gearbox or a Torxis servo motor which are ridiculously powerful and function directly at 12 V.
