Abstract: Systems and methods for positioning a mobile assembly relative to a stationary assembly may include a first position sensing device, a controller, and a sensor attached to the mobile assembly. The first position sensing device senses first data representative of a relative position between the mobile assembly and the stationary assembly based on a wireless signal. The controller determines a first trajectory based on the first data. The sensor collects second data representative of a displacement executed by the mobile assembly. The controller determines a calibration offset for the first trajectory based on the second data following completion of the displacement of the mobile assembly from the first position to the second position along the first trajectory. The controller further iteratively improves the calibration offset following completion of subsequent displacements of the mobile assembly from a third (remote) position to a fourth (proximate) position along subsequent first trajectories.

Abstract: A socket of an automatic coupler assembly is arranged for receiving a plug along a first direction. The socket includes a first means for limiting the movement of the plug in the first direction and a second means for blocking the movement of the plug in a second direction opposite to the first direction.

Abstract: A moving device comprises at least a first element provided with main magnets and a second element provided with coils. The main magnets are arranged in a grid of rows and columns, wherein main magnets in adjacent rows are oppositely polarised and staggered relative to each other. The coils can be energized for moving the first element relative to the second element in a direction parallel to the rows as well as in a direction parallel to the columns. Auxiliary magnets of the same polarity are disposed between the main magnets at least in a number of rows, wherein the strength of the magnetic field of said auxiliary magnets is different from that of the main magnets.
