Methods and Systems for Simultaneous Localization and Calibration
20200242396 · 2020-07-30 ·

Examples relate to simultaneous localization and calibration. An example implementation may involve receiving sensor data indicative of markers detected by a sensor on a vehicle located at vehicle poses within an environment, and determining a pose graph representing the vehicle poses and the markers. For instance, the pose graph may include edges associated with a cost function representing a distance measurement between matching marker detections at different vehicle poses. The distance measurement may incorporate the different vehicle poses and a sensor pose on the vehicle. The implementation may further involve determining a sensor pose transform representing the sensor pose on the vehicle that optimizes the cost function associated with the edges in the pose graph, and providing the sensor pose transform. In further examples, motion model parameters of the vehicle may be optimized as part of a graph-based system as well or instead of sensor calibration.

TRANSPORT TROLLEY

A transport trolley for transporting a load comprising a base mounted on motorized wheels, a deck mounted to be translationally mobile on the base in a direction of translation, a first motorized system displacing the deck, a hexapod platform comprising a platform and a set of six jacks in which each is mounted articulated between the deck and the platform. The platform comprises a plurality of bearing points configured to come under the load and each bearing point takes the form of a receptacle with its opening oriented upwards. A control unit controls each motorized wheel, the first motorized system and each jack. The use of a hexapod platform makes it possible to finely position the wing at its position of fixing onto the fuselage and the use of a mobile deck supporting the hexapod platform allows for adjustability of the position despite a smaller footprint around the aircraft.

Proactively reducing vibrations in an industrial truck

An industrial truck is described, such as a tri-lateral sideloader, comprising a truck body, wheels connected to the truck body by wheel suspensions, a mast, a plurality of operating components designed to carry out operating functions of the industrial truck, a control unit designed to actuate the operating components, and a detection apparatus designed to detect an operating parameter and/or a parameter of the environment. Here, the industrial truck further comprises a prediction unit designed to predict the occurrence of vibrations on the industrial truck based on data provided by the detection apparatus and to provide prediction data to the control unit. Based on the prediction data, the control unit is further designed to adapt the actuation of at least one of the operating components and/or to actuate an apparatus for reducing vibrations such that the vibrations predicted by the prediction unit are reduced.

Lifting system and method for lifting and/or lowering loads
10556784 · 2020-02-11 · ·

A lifting system for lifting and/or lowering loads having a lifting apparatus which is suitable for conveying loads along a lifting direction from a first transfer position into a second transfer position and along a lowering direction from the second transfer position to the first transfer position, and a conveyor apparatus which is suitable for taking on, at the first and/or the second transfer position, the loads conveyed by the lifting apparatus. The conveyor apparatus has at least one holding pendulum which is pivotable into a holding position, wherein the lifting apparatus has at least one holding receptacle for the holding pendulum, wherein the holding pendulum, in the holding position, can be placed in engagement with the holding receptacle, by a movement of the holding receptacle in the lowering direction, such that a movement of the lifting apparatus in the lowering direction is blocked, and/or the holding pendulum, in the holding position, can be placed in engagement with the holding receptacle, by a movement of the holding receptacle in the lifting direction, in such a way that a movement of the lifting apparatus in the lifting direction is blocked. The holding receptacle has a first guide track, wherein the first guide track is designed so as, during a movement of the holding receptacle along the lifting direction or the lowering direction, to move the holding pendulum into a first position in which the holding pendulum cannot be placed in engagement with the holding receptacle.

DOLLY WITH AUTOMATED HEIGHT ADJUSTMENT
20200039551 · 2020-02-06 · ·

A dolly includes an actuated platform and obstruction sensor as well as a camera and a depth sensor. The eye height of a user is determined according to outputs of the camera and depth sensor. The platform is then moved to an elbow height determined based on the eye height and the depth sensor is moved to a position above the platform. In response to detecting obstruction of the obstruction sensor, the platform is lowered. Upon completion of loading, the platform is lowered to a lowest position. A stand may be retracted upon lowering of the platform to its lowest position.
