  • Patent number: 12275153
    Abstract: Disclosed is a control method for delivery robots, wherein a distribution area has a preset home point. The control method includes: identifying a second delivery robot that obstructs a first delivery robot, wherein the first delivery robot is in a working state of heading to one or more target positions, and the second delivery robot is in an idle state; determining a distance between the second delivery robot and the home point; and controlling the second delivery robot to avoid the first delivery robot according to the distance between the second delivery robot and the home point. In view of the situation that an idle delivery robot may obstruct a delivery robot performing a task, the disclosure proposes an avoidance judgment logic to control the idle delivery robot to avoid, thereby improving distribution efficiency and preventing congestion.

    Abstract: Disclosed are a collision avoidance method for a moving device, a collision avoidance apparatus for a moving device, and a computer-readable storage medium. This application relates to the field of artificial intelligence technologies. According to the method, a parking direction of a moving device in an avoidance area is adjusted, so that a startup time used by the moving device after avoidance completes may be reduced. The method includes: determining a target path direction of a moving device; determining a first candidate parking direction and a second candidate parking direction; determining, based on the target path direction, a target parking direction of the moving device from the first candidate parking direction and the second candidate parking direction; and controlling, based on the target parking direction, the moving device to be parked in the avoidance area.

  • Publication number: 20250018936
    Abstract: A computer includes a processor and a memory, and the memory stores instructions executable by the processor to determine an availability metric, determine a maneuver metric, determine a threat number based on a comparison of the availability metric and the maneuver metric, and in response to the threat number exceeding a threshold, actuate a vehicle system to operate one of the first vehicle or the second vehicle. The availability metric is a kinematic quantity available to a first vehicle to perform an operation to maneuver the first vehicle away from a projected path of a second vehicle. The maneuver metric is a kinematic quantity estimated to be used by the first vehicle to perform the operation to maneuver the first vehicle away from the projected path of the second vehicle. The maneuver metric is measured in the same units as the availability metric.
