Abstract: A system includes a remotely-operated ground vehicle having first and second lift members, a first lift mechanism coupled to the first lift member, and a second lift mechanism coupled to the second lift member, where the first and second lift mechanisms are positioned at different angles with respect to a ground surface. The first and second lift members may be positioned at opposite sides of a front end of the vehicle and may be controlled by a single motor. The lift mechanisms may have a body portion including first and second prongs separated by an opening, with a plurality of magnets embedded within the body portion near the intersection of the first and second prongs. A communication relay may be secured to each lift mechanism via the opening and a magnetic coupling between the magnets embedded within the body portion and magnets embedded within the communication relay.

Abstract: A system includes a first drive module connected to a first end of a linkage arm and a second drive module connected to a second end of the linkage arm. Two magnetic wheels are connected to each of the first and second drive modules. The first and second drive modules may be independently controlled or controlled using a coordinated controller. The linkage arm may include a first linkage arm portion having at least one degree of freedom with respect to a connected second linkage arm portion, which may be connected via a hinged or ball-joint connection. One or both ends of the linkage arm may have at least one degree of freedom with respect to its respectively connected drive module. Additional linkage arms and drive modules may be connected to form a multi-segment system.

Abstract: A method involves using a first lift mechanism coupled to a remotely-operated ground vehicle to engage a first communication relay and position it at a first angle above a ground surface. A second lift mechanism coupled to the remotely-operated ground vehicle is then used to engage a second communication relay. With a single motion by the remotely-operated ground vehicle, the second communication relay is positioned at a second angle above the ground surface and the first communication relay at a third angle above the ground surface. The third angle is greater than both the first angle and the second angle. The second angle is greater than or equal to the first angle. The first communication relay may then be deployed by the remotely-operated ground vehicle at a first location and the second communication relay may be deployed at a second location.
