Swivl C Series Robot/SW3322-C1

I want to use this for live broadcast. Can you use this with Facebook live?

What size case can I put on our iPad minis that will still fit snuggly in the swivl base?

can you mount it on a tripod or do you need a table/desk to set it on?

Does the base that holds the phone serve as the microphone, or does it rely on the microphone in your phone
