  • Dynamic flex compensation, coordinated hoist control, and anti-sway control for load handling machines
    Patent number: 12227395
    Abstract: Various example embodiments relate to motion control of a target such as a suspended load. An apparatus may comprise: a floating base comprising an exteroceptive observation system configured to measure a position or velocity of at least one target with respect to a reference coordinate frame moving with the floating base. The floating base may further comprise an inertial measurement unit configured to measure at least one inertial state of the floating base with respect to an inertial reference coordinate frame. Position or velocity compensation for the at least one target may be performed based on the at least one inertial state of the floating base.

  • CONTROLLER AND METHOD
    Publication number: 20240210955
    Abstract: Disclosed is a load handling controller and a method for localizing a load handling vehicle and a load target. A spatial map describing a surrounding of the load handling vehicle is obtained. First sensor signals are received from a first sensor system for generating point clouds of the surrounding of the load handling vehicle and second sensor signals are received from a second sensor system for generating images of the surrounding of the load handling vehicle. The second sensor signals are synchronized in time with the first sensor signals. The load handling vehicle and the load target are localized in the spatial map based on the first sensor signals and the second sensor signals.
