I have them at the beginning of a new game. How do I interact with them ??

Just put them down, give them the equipment

Thank You !! Thank You for the assist and Thank You for what you do Sir.

A few stupid questions. =)
What is a point in roboport if they are drons itself?
What is a point to use fuel if they have reactor installed?
What is that little shadow (https://i.imgur.com/iPsqDZ2.png https://gfycat.com/windywearyanemonecrab), what follows one of them?

Good Questions! I would add some questions:
1. "How can we disable them?" Is the only way to do so picking them up?
2. If I gave them a deconstruct order, they pick everything up and bring them to my inventory, except Wooden Power Poles, they put them into the fuel slot ;) Should it be like this? (using Krastorio 2 Mod)

Double post, wrong location.
