Patent number: 12275153Abstract: 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.Type: GrantFiled: September 15, 2022Date of Patent: April 15, 2025Assignee: Keenon Robotics Co., Ltd.Inventors: Meihua Zhang, Yuhao Liu, Yayun Yang
