Immediately, diagrams and schematics appeared in my vision. I examined them in fascination. The roamers were constructed with radial symmetry—no real front or back. Eight limbs matched with eight sets of sensors. Each appendage could be a leg or could split into three digits to act as a manipulator. In addition, different legs had specialized functions built in. Some legs could be screwdrivers, grinders, torches, and cutters of various kinds. Some of the tech was brand new as well. One neat gizmo was a magnetically controlled plasma cutter that I would consider the real-life version of a light saber.
