Rotating head

Hi

what would be the best hardware parts to build a rotating head just like a real tank (with the cannon)? Simple motor, stepper motor, servo?

Thanks

For now, maybe a GoPro, later a turret.

It depends on the size you are considering and the weight of the turret. Can you provide additional details?

You mean a camera? We can’t help much if you don’t provide details.
