Abstract
A mobile robot, a controller, and a mobile robot control method are provided. The mobile robot includes a processor. The processor is configured to execute program instructions to implement the following steps: when it is determined that the mobile robot deviates from a preset path, determining a return point of the preset path that is closest to the mobile robot; generating a temporary path based on the return point; and driving the mobile robot to return to the preset path according to the temporary path.
Claims18
A mobile robot, comprising a processor, the processor being configured to perform program instructions to implement the following steps:
- when it is determined that the mobile robot deviates from a preset path, determining a return point of the preset path that is closest to the mobile robot;
- generating a temporary path based on the return point, comprising:
- receiving a current pose of the mobile robot that is sensed by a sensor, and determining a start point according to the current pose;
- and
- selectively setting a waypoint according to the start point and the return point, to generate the temporary path, comprising:
- generating a plurality of candidate paths between the start point and the return point;
- and
- selecting one of the plurality of candidate paths as the temporary path;
- and
- driving the mobile robot to return to the preset path according to the temporary path.
A controller, comprising a processor, the processor being configured to perform program instructions to implement the following steps:
- when it is determined that a mobile robot deviates from a preset path, determining a return point of the preset path that is closest to the mobile robot;
- generating a temporary path based on the return point, comprising:
- receiving a current pose of the mobile robot that is sensed by a sensor, and determining a start point according to the current pose;
- and
- selectively setting a waypoint according to the start point and the return point, to generate the temporary path, comprising:
- generating a plurality of candidate paths between the start point and the return point;
- and
- selecting one of the plurality of candidate paths as the temporary path;
- and
- driving the mobile robot to return to the preset path according to the temporary path.
A mobile robot control method, comprising:
- when it is determined that a mobile robot deviates from a preset path, determining a return point of the preset path that is closest to the mobile robot;
- generating a temporary path based on the return point, comprising:
- receiving a current pose of the mobile robot that is sensed by a sensor, and determining a start point according to the current pose;
- and
- selectively setting a waypoint according to the start point and the return point, to generate the temporary path, comprising:
- generating a plurality of candidate paths between the start point and the return point;
- and
- selecting one of the plurality of candidate paths as the temporary path;
- and
- driving the mobile robot to return to the preset path according to the temporary path.
