Hello..my name is nizam and i'm new here..

I want to design a schematic of a circuit but I have facing some problems..
For my robot project, I want to use a PIC18F252 and 5 servo motors. The servo are high torque servo, 15kg/cm and 20 kg/cm. This robot use 2 IR sensors

1. How to supply enough voltage and current to all the servo motors, is it needed to add another supply like LiPo battery or anything..?

2. Can I straightly connect the servo to the PIC like in the tutorial..?

I hope you can help me.. :)

Hi,

You can and should connect the LiPo directly to your (servo) motors. If you use a voltage regulator it will limit how much current can be drawn and therefore make the power density that LiPo batteries offer pointless.
