Patent ID: 8869338

Claim:
A sheet affixing method comprising: placing a sheet against a first surface of a platform of a robot, the robot configured to move in an environment in accordance with logic contained in an on-board processor; applying a force in a first direction to a second forward portion of a second jaw of a first trap, wherein the first trap comprises: a first jaw, comprising a first base portion and a first forward portion, the first forward portion having a first forward surface; and the second jaw, comprising a second base portion and the second forward portion, the second base portion of the second jaw spaced from the first base portion of the first jaw, and the second forward portion having a second forward surface and flexible in at least a first direction substantially orthogonal to the second forward portion, and wherein the applied force causes the second jaw to flex in the first direction so as to space the second forward surface, of the second forward portion of the second jaw, further from the first forward surface of the first forward portion of the first jaw than prior to the application of the force; inserting, while applying the force to the second forward portion, a portion of the second portion of the sheet at least into the space between the first forward surface of the first forward portion of the first jaw of the first trap and the second forward surface of the second forward portion of the second jaw of the first trap; removing the applied force from the second forward portion of the second jaw of the first trap, wherein when the second jaw is relaxed, the second forward portion of the second jaw is substantially coplanar with the first forward portion of the first jaw and the second forward surface of the second forward portion of the second jaw faces the first forward surface of the first forward portion of the first jaw; and affixing the third portion of the sheet in a second trap.
