A common drone sold and used by Nimbus Heavy Industries, or NHI, a megacorporation specializing in heavy machinery, starship parts, robotics, etc... this is basically a heavy lifter, used in shipyards, ports, and construction sites, moving heavy cargo or equipment into place. The mover is semi-autonomous and can act reasonably intelligently on its own, but they need overseers and instructions. Movers are also equipped with spatial traction systems to increase or decrease the amount of inertia that is needed for them to be moved, allowing them to stay far more stable than units equipped only with gravity resist pads... the legs allow it to have a stable solid platform when moving and holding heavy loads, grav resist pads would need constant adjustment to keep a unit in place.

These drones can also be equipped with laser weapons and shield generators to serve as defensive units in a hostile construction environment. Though even the hauler arms are more than powerful enough to overturn medium sized vehicles and bat around intruders.

Alma and crew have destroyed a great many of these in their adventures.
