Problems solved by technology

[0002] The mobile robot adopts an autonomous navigation algorithm and does not need to lay two-dimensional codes, magnetic strips and other tracks. It is applied to the intelligent handling of materials. In the process of intelligent handling, it is necessary to complete tasks such as automatic identification of materials and automatic retrieving. If the location of the goods to be transferred If it is too close or similar to the surrounding features, there will be misrecognition and the wrong material will be taken. The existing technology cannot solve this defect, resulting in low efficiency and accuracy of material retrieving, or it cannot meet the requirements of placing the same or similar products in the same area at the same time. materials, so it cannot meet the requirements of fully automatic transportation

Embodiment 1

[0047] like figure 1 , figure 2 As shown, Embodiment 1 of the present invention provides a method for accurately retrieving materials by a mobile robot, including the following steps:

[0048] Step S1: The mobile robot sets the cargo placement point as the initial site;

[0049] Step S2: The mobile robot arrives at the docking point according to the received instruction content, the sensor identifies the goods, and obtains the deviation value;

[0050] Step S3: Calculate the location of the identified cargo on the map according to the deviation value, compare it with the location of the initial station, judge whether the identified cargo is the cargo to be shipped, and take the material according to the result.

[0051] In this embodiment, the judging whether the identified goods are goods to be shipped, and taking materials according to the results further includes:

[0052] Within the allowable error range, if the position of the goods is consistent with the position of ...

Embodiment 2

[0079] like Figure 5 As shown, Embodiment 2 of the present invention provides a system for precise material retrieving by a mobile robot, using a method for precise reclaiming by a mobile robot, including a mobile robot 1 and a sensor 2, the sensor 2 is installed on the mobile robot 1, The sensor 2 can be a sensor that can identify the distance, such as a laser radar, a camera, etc., the mobile robot 1 sets the cargo placement point as the initial site, and arrives at the docking point according to the received instruction content, and the deviation value from the cargo identified by the sensor 2 , the mobile robot 1 calculates the position of the identified cargo according to the deviation value, and compares it with the position of the initial site.

[0080] In this embodiment, the mobile robot includes a control system 11 and a motion system 12. The control system 11 includes a task management unit 111 and a navigation unit 112. The task management unit 111 sets docking po...

Abstract

The invention discloses a method and a system for accurately taking materials by a mobile robot. The method comprises the following steps: the mobile robot sets a goods placement point as an initial station; the mobile robot arrives at the butt joint point according to the received instruction content, and the sensor identifies goods to obtain a deviation value; calculating the position of the identified goods in the map according to the deviation value, comparing the position of the identified goods with the position of the initial station, judging whether the identified goods are to-be-transported goods or not, and taking the goods according to a result; within an allowable error range, if the position of the goods is same with the position of the initial station, starting a material taking unit; if the position of the goods is inconsistent with the position of the initial station, continuing to search for consistent goods; and if the consistent goods are found, starting the materialtaking unit, and if not, outputting an alarm. The method and the system have the effect of accurately identifying the goods, and the efficiency and the accuracy of intelligent transportation can be improved.

Description

technical field [0001] The invention relates to the field of intelligent transportation, in particular to a method and a system for accurately picking materials by a mobile robot. Background technique [0002] The mobile robot adopts an autonomous navigation algorithm and does not need to lay two-dimensional codes, magnetic strips and other tracks. It is applied to the intelligent handling of materials. In the process of intelligent handling, it is necessary to complete tasks such as automatic identification of materials and automatic retrieving. If the location of the goods to be transferred If it is too close or similar to the surrounding features, there will be misrecognition and the wrong material will be taken. The existing technology cannot solve this defect, resulting in low efficiency and accuracy of material retrieving, or it cannot meet the requirements of placing the same or similar products in the same area at the same time. materials, so it cannot meet the requi...
