Recently, the astronauts on board the International Space Station performed a routine "walk-off" maneuver with the large, 58-foot-long robotic arm attached to the orbiting laboratory. The robotic arm, known as Canadarm2 because it was supplied by the Canadian Space Agency, is something of a modern engineering miracle—it can effectively move around the exterior of the large space station like an inchworm because both ends are essentially identical. However, after this particular walk-off maneuver, the robotic arm, along with the mobile transporter that guides it along the main truss of the space station, could no longer be moved.
