how do i choose the power supply for this project

[sapik900906]

hii, i'm doing my final year project,
i'm using SC16A to control 7 RC servo motor (C40R) and 3 servo motor in small robot griper.
but the problem is, how to providing the power supply, any one can help me? perhaps with the cheapest solution,
thank

Yupe, the power source for servo motor is always a problem. You can't connect a 12V or 7.2V battery to them as these voltages are higher than the C40R voltage spec. These voltages might burnt the servo motor.
I am suggesting you to use the ATX power supply. You can power up the servo motor from the 5V power of ATX power supply. Normally ATX power supply comes with high current capacity. There is a good tutorial from Cytron on Hacking ATX Power Supply. You should go through it.

but if i want more mobility in my robot? can someone suggesting any solution? can i use the 6V lead seal battery? do i need any circuit?

Use the higher voltage battery but add regulator circuit to match with your servo voltage rating

ooo. that seem the best solution i have here, hehe. but since i'm not know much about the circuit, then here is my other problem. to construct the regulator circuit! ooo no! anyone can help me?

You can refer to the power part of DIY project PR18 schematic.

beside that, can i use any dc adapter?

DC adapter for?

for the servo motor

[zhenning]

Yes you can.
