Embodiment 1

[0048] The first sensor of the sensor group receives the first signal fed back by the robot and the second sensor receives the second signal fed back by the robot, and the robot travels a predetermined distance according to the set route.

Embodiment 2

[0050] When the robot is in the forward direction or at the origin, at least one of the first signal and the second signal cannot be received. After the robot is controlled to travel a predetermined distance according to the set route, if the result of the continuous judgment is still the first signal and the At least one of the second signals cannot be received, and the robot is controlled to return to the position of the sensor group, wherein the predetermined distance traveled by the robot is 1 / 4-1 / 2 of the driving threshold of the robot, wherein, the driving threshold=|detection threshold - the distance of the robot from the sensor set|.

Embodiment 3

[0052] When the robot is at the origin, at least one of the first signal and the second signal cannot be received. After the robot is controlled to travel a predetermined distance according to the set route, if the result of continuing judgment is still the first signal and the second signal At least one of them cannot be received, control the robot to return to the position of the sensor group, wherein the predetermined distance traveled by the robot is 1 / 5 of the driving threshold of the robot, wherein, the driving threshold=|detection threshold-the distance between the robot and the sensor group |.

Abstract

The invention provides a storage robot positioning system and method. The method includes the following steps: Step 1, whether a first sensor in a sensor group receives a first signal fed back by a robot and whether a second sensor receives a second signal fed back by the robot are determined; step 2, if the first signal and the second signal are both received, the robot continues to travel predetermined distance according to a set route and the step 1 is repeated, and if at least one of the first signal and the second signal cannot be received, a step 3 is proceeded to; and step 3, the robotcontinues to travel predetermined distance according to the set route, whether the first signal and the second signal are both received is determined, the step 1 is repeated if the first signal and the second signal are both received, and if at least one of the first signal and the second signal cannot be received, the robot is controlled to return to the position of the sensor group. The storagerobot positioning system and method improve the accuracy of positioning of the robot, thereby improving the control precision, avoid accidents and improve the efficiency of transportation.
