The present disclosure provides an external parameter calibration method for robot sensors as well as an apparatus, robot and storage medium with the same. The method includes: obtaining first sensor data and second sensor data obtained through a first sensor and a second sensor of the robot by collecting position information of a calibration reference object and converting to a same coordinate system to obtain corresponding first converted sensor data and second converted sensor data, thereby determining a first coordinate and a second coordinate of a reference point of the calibration reference object; using the first coordinate and the second coordinate are as a set of coordinate data; repeating the above-mentioned steps to obtain N sets of the coordinate data to calculate the external parameter between the first sensor and the second sensor in response to a relative positional relationship between the robot and the calibration reference object being changed.

The present disclosure provides a movement control method for a robot as well as an apparatus and a robot using the same. The method includes: obtaining a starting position and an ending position of the robot, in response to a movement instruction being detected; determining a movement path of the robot based on the starting position and the ending position; obtaining pass qualification information of the robot, if the movement path intersects a line corresponding to a preset virtual wall; and moving the robot to the ending position according to the movement path, if the pass qualification information identifying the robot is allowed to traverse the virtual wall. By obtaining the pass qualification information, the robot can return to the working area from the non-working area in the case of an abnormality, while ensuring that the robot does not actively traverse from the working area to the non-working area.

The present disclosure provides a robot distance measuring method and apparatus as well as a robot using the same. The method includes: obtaining a plurality of relative position parameters of a robot from a plurality of ranging sensors; determining an installation distance between each two of the ranging sensors based on the plurality of relative position parameters; determining a sum of the installation distance of each looping arrangement of the plurality of ranging sensors based on the installation distance between each two of the ranging sensors; and enabling the plurality of ranging sensors sequentially to perform obstacle ranging according to a preset looping rule. Since the adjacent ranging sensors are avoided to range simultaneously or sequentially, the interference of the adjacent ranging sensors can be minimized, the accuracy of measuring the distance of the surrounding obstacles can be improved, thereby improving the navigation performance of the robot.
