Summoning complexity is tied to both physical complexity and intelligence, right? Does one carry more weight than the other?

To frame the question; Summoning a database AI in a simple PDA or storage device: High intelligence but low physical complexity. Summmoning a surveillance drone that can both fly, walk, and record in various filters like Night Vision and Thermals but with basic pathfinding intelligence and not much else; Low intelligence, high physical complexity. Would they be about equal in difficulty, or would one be higher in difficulty?

In addition, would a mental link for Machina house members be some kind of direct input to the technology? Would their link allow them to interface and command directly, rather than using something like a controller or a computer?
