My goal is to build a 4-legged robot that I can hook to a wireless ps4 controller and walk it around. My problem lies in powering the robot without the use of my laptop/computer.
My Arduino is plugged into a PCA9685 which allows me to hook up a max of 16 servos. Each leg of the robot uses 2 servos for a total of 8 servos (TowerPro SG90's). The PCA9685 requires power so it can power the servos and I can't seem to figure out a good way of doing this. I am very new to the electrical engineering world so giving components the correct power is still quite confusing.
What suggestions do you have for powering this robot?
