Abstract
Techniques for transferring torque between a first unit, such as a mobile machine or a robot, and a second unit, such as a fixed or stationary machine. The units are arranged such that a drive coupler of the first unit designed for delivering torque about a drive axis can engage the driven coupler, which belongs to the second unit and has a driven axis, along an engagement direction that is nearly perpendicular to the direction of the driven axis. A lateral displacement mechanism of the first unit achieves a first-order coaxial alignment between the drive and driven axes. Additional measures are provided for improving engagement, coupling and reducing the level of axial misalignment. Techniques disclosed are tolerant of imprecise alignment between the drive and driven couplers.
