Ty got out and opened a cargo hatch on the side, releasing a couple of siwis that began moving across the ground in their distinctive elbowing style of locomotion, as well as a couple of buckies that began rolling about seeking high ground from which to establish observation posts and communications links. Their main objective now was to get the glider tied down so it wouldn’t blow away in a stray gale. The siwis were essentially earth sciences robots, good at digging and tunneling. In a few minutes’ time, with a bit of guidance from Doc, they were able to plant anchors in some sturdy-looking boulders flanking the riverbed. Ty and Bard ran ropes from those to the ends of the glider’s wings and made it fast while Beled stalked restlessly around the perimeter. Kath Two and Ariane deployed the grabb that Doc used to get about in places like this. It served the same function as a wheelchair, only with legs, so that it could pick its way along terrain where even able-bodied humans would have difficulty making headway. Meanwhile Memmie got him bundled up and ready. Einstein watched it all and asked only a few hundred questions, most of which were cheerfully answered by Doc himself. Einstein would have seen much of this sort of technology on videos in the RIZ, but this was his first direct experience of it.
