US 2020/0346348 A1 · Method and Device for Controlling a Great Number of Robots to Emergently Stop

Abstract

A method and a device for controlling a number of robots to emergency stop are provided. The method includes arranging multiple position points in a site where robots work and position identifiers corresponding to the position points, and providing corresponding recognizers at bottoms of the robots; when fault signals reported by the robots are detected, determining, according to the fault signals, whether all the robots in the site need to be controlled to emergency stop, wherein if yes, according to current positions and moving speeds of the robots, position points in the site are allocated to the robots as respective emergency stop positions, the robots are controlled to move to the corresponding emergency stop positions, and thereafter the robots are controlled to stop movement. The device comprises a configuration module, a determination module, an allocation module and a control module.

Dependent claims

A method for controlling a number of robots to emergency stop, comprising steps of:

arranging multiple position points in a site where the robots work, configuring position identifiers respectively for the multiple position points, and providing a recognizer at a bottom of each robot, with the recognizer configured for recognizing the position identifier of the robot;
and
monitoring working situations of the robots in the site, and judging, when a fault signal reported by the robot(s) is detected, whether all the robots in the site need to be controlled to emergency stop, according to the fault signal,
wherein if yes, a current position and a moving speed of each of the robots are detected, and each of the robots is allocated with a position point in the site as a respective emergency stop position, according to the current position and the moving speed of each of the robots, and
each of the robots is controlled to move to a corresponding emergency stop position, and each of the robots is controlled to stop movement after the robot moves to the corresponding emergency stop position.
