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 present invention provides a storage robot positioning system and method, comprising: step 1, judging whether the first sensor in the sensor group has received the first signal fed back by the robot and whether the second sensor has received the second signal fed back by the robot; step 2. If both the first signal and the second signal are received, the robot will continue to drive for a predetermined distance according to the set route, and repeat step 1. If at least one of the first signal and the second signal cannot be received, go to step 3 ; Step 3, the robot continues to travel a predetermined distance according to the set route, and judges whether the first signal and the second signal are both received, if both are received, repeat step 1, if at least one of the first signal and the second signal If it cannot be received, the robot is controlled to return to the position of the sensor group. This application improves the positioning accuracy of the robot, thereby improving the control precision; on the other hand, avoiding accidents and improving transportation efficiency.

Description

technical field [0001] The invention relates to the field of warehousing robot positioning, in particular to a warehousing robot positioning system and method. Background technique [0002] In the logistics industry, traditional warehouse management can only do the warehousing, storage, outbound, query, inventory and maintenance of items, and these processes are all manually operated, but how to accurately inform the operation It is not only inefficient, but also has a high error rate. Coupled with the flow of personnel, the work of finding and locating items becomes even more difficult. The complexity and diversity of warehouse management make the current warehouse management mode relying on manual and paper inventory records unable to handle such a huge workload.
