Not sure what controller to get for computer controlled machine

I’m looking to use a computer to control a larger robot I am building to get familiar with building machines like this. However, I am unsure what motor controller or components I need to control up to 6 servos for the arms of this robot. I only intend for this iteration to have two arms, immobile, and can hear and speak. I’m planning on using 6 MG995 Tower pros to power the arm as per suggestion. Until I can get Linux installed, I am trying to use the Microsoft system. I’ve been looking around at other robots such as Polyro, but I’m avoiding the expensive bioloid parts.
