The demonstration involved two small satellites, with one issuing to the other an instruction to move. Deep Space Industries says: Small satellites are, by definition, easier to launch than larger apparatus, and cheaper too. Working in swarms, small satellites can replicate the same effect. While humans have maneuvered satellites around each other for decades, in the past it’s required direct human control. Letting the machines reposition themselves, especially when it comes to busywork like “not colliding into each other,” is a pretty good use of robot brains. Gizmag
