I am currently working on a project to make a hexapod (which I would like to control via bluetooth) but I have some questions and I would appreciate if someone helped me.
I’m thinking about using a 24 ch maestro servo controller to control 18 servos (which have 8kg/cm torque), but I am wondering if is possible to connect a 7.4 V LiPo battery to the maestro to power all the servos directly. I mean, do I need any UBEC? And If I need any, is it better a single powerful UBEC or more smaller UBECs?
I would like to control my hexapod with my android phone using bluetooth and I was thinking about buying a bluetooth module like RN-42. Is there any sketch that shows some code of the maestro controller linked to the BT module to receive commands from another device?
Thank you in advance.
