Power supply question?

Help & Support Robot Parts

[size=2]I have finally decided to get the lynmotion quadruped and now i need to decided on a power supply. This is where thing get confusing. The manufacturer suggested “[font=Helvetica Neue, Helvetica, Arial, sans-serif][highlight=#ffffff]one (1x) 4.8V to 6V battery (6V is preferable) and one (1x) 9V battery. If you prefer only having one power supply, you can purchase a voltage regulator.” . [/highlight][/font][font=Helvetica Neue, Helvetica, Arial, sans-serif][highlight=#ffffff]So do i just buy a 9v and a voltage regulator if i just want one power supply ??? In addition, i will also add a [/highlight][/font][font=Helvetica Neue, Helvetica, Arial, sans-serif]raspberry pi for video streaming. So is there a battery pack that be able to power everything and still fit on the robot ?[/font]
[font=Helvetica Neue, Helvetica, Arial, sans-serif][/font]sorry if this is a noob question, electronics is not my strong suit .

Ideally you should be using a battery to power the robot, and we suggest the following:

You’ll likely also need a 9V battery to ensure the logic does not brown out.
We currently don’t have a proposed setup for adding a Raspberry Pi, which requires 5V power.
You might consider a voltage regulator to get 5V. Take note of the minimum input voltage to get 5V output.

again im still confuse. Do i only need the 6v or do i need to buy both the 6v and 9v ??? and how exactly i achieved single power supply with a voltage regulator ??

THank you

You need the 6V to power the servos, and the 9V to power the logic voltage on the microcontroller.
To power the Raspberry Pi, you need a voltage regulator (you will need to split the output from the 6V battery to the servos and the voltage regulator).
