Problems solved by technology
[0003] At present, when the robot's environment is close to obstacles or the radar data is insufficient, the radar observation data is compared with the robot's built-in map, and the precise position of the robot cannot be obtained, resulting in a problem of positioning failure.

The invention belongs to the technical field of robots, and discloses a robot repositioning method and system, a robot and a storage medium. The method comprises the steps of obtaining data information of a current position, and judging whether the valid data volume is greater than a preset threshold value or not; if the valid data volume is less than the preset threshold value, entering an exploration mode, and calculating a plurality of exploration points meeting a preset exploration condition; judging whether navigation from the current position to the first exploration point is successful or not; if the navigation from the current position to the first exploration point is successful, taking the first exploration point as the current position, and judging whether the valid data volume of the current position is greater than the preset threshold value or not; if the valid data volume of the current position is greater than or equal to the preset threshold value, executing repositioning at the current position, and judging whether repositioning succeeds or not; and if the repositioning is successful, ending the repositioning. According to the invention, the repositioning precision can be improved through multiple times of repositioning in the modes of repositioning, exploration and repositioning.
Description
technical field [0001] The present application relates to the field of robot technology, in particular to a robot relocation method, system, robot and storage medium. Background technique [0002] With the development of robot technology, household robots that can automatically locate and move are becoming more and more popular. However, during the use of this type of robot, there may be problems with inaccurate sending and positioning, such as power failure in abnormal situations, the user actively moving the machine, etc., which may cause the original positioning of the robot to fail and require repositioning. As an important basis for robot intelligent navigation and environment exploration, relocalization is one of the key technologies for robots to achieve complete autonomy. [0003] At present, when the robot's environment is close to obstacles or the radar data is insufficient, the data observed by the radar is compared with the built-in map of the robot, and the pre...
