The practical applications of using a robot to weave a structure is that it could become a deployable platform capable of building a large structure, like say a gantryplatform inside or around another large structure.
There had also been indications of construction activity on the rocket site's upper gantryplatform "required for future launches of long-range rockets", it said.
The majority of the Replicator's internal space is wide open, save for a build platform that can be adjusted up and down by turning a threaded screw and the gantry atop the space that houses the Stepstruder MK8, whose front is monopolized by a large pair of fans.
