Problems solved by technology

[0005] However, in the information processing device described in Patent Document 1, since only unconfirmed persons are recognized, the driving of the robot is restricted.
Therefore, when the robot is installed in an environment where an uncertain number of people come and go, there is a technical problem that the drive is frequently restricted and the productivity of the robot's work is reduced.

no. 1 approach

[0026] First, the robot system according to the first embodiment will be described.

[0027] figure 1 It is a figure which shows the robot system which concerns on 1st Embodiment. figure 2 yes figure 1 A schematic diagram of the robotic system is shown. image 3 yes means figure 1 as well as figure 2 A block diagram of an example of the hardware configuration of the robot system shown. Figure 4 is used to describe in more detail image 3 functional block diagram.

[0028] In addition, in figure 1 In FIG. 3 , an X axis, a Y axis, and a Z axis are shown as three axes orthogonal to each other. In addition, in this specification, "connection" includes both the case of being directly connected and the case of being indirectly connected through an arbitrary member.

[0029] 1.1 Robot system

[0030] figure 1 The illustrated robot system 100 is used in operations such as holding, conveying, and assembling a work object. The robot system 100 includes: a robot 1 ; a cont...

no. 2 approach

[0100] Next, a robot system according to a second embodiment will be described.

[0101] Figure 8 is a schematic diagram of the robot system according to the second embodiment.

[0102] Hereinafter, the second embodiment will be described, but in the following description, the differences from the first embodiment will be mainly described, and the description of the same matters will be omitted. In addition, in Figure 8 In , the same reference numerals are assigned to the same structures as those in the first embodiment.

[0103] The second embodiment is the same as the first embodiment except that the control by the control unit 51 is different.

[0104]In the first embodiment described above, the area 1000 is set around the robot 1 , and when the person 9 enters the area 1000 , the driving of the robot 1 is restricted. In contrast, in the present embodiment, the region 1000 in which the driving of the robot 1 is restricted is divided into two stages. That is, another ...

no. 3 approach

[0118] Next, a robot system according to a third embodiment will be described.

[0119] Figure 9 to Figure 13 Each is a schematic diagram of the robot system according to the third embodiment.

[0120] Hereinafter, the third embodiment will be described, but in the following description, the differences from the first embodiment will be mainly described, and the description of the same matters will be omitted. In addition, in Figure 9 to Figure 13 In , the same reference numerals are assigned to the same structures as those in the first embodiment.

[0121] The third embodiment is the same as the first embodiment except that the control by the control unit 51 is different.

[0122] Figure 9 This is an example in which there are two persons 9A and 9B inside the imaging range 30 . on the other hand, Figure 10 This is an example in which there are three persons 9A, 9B, and 9C inside the imaging range 30 . also, Figure 9 as well as Figure 10 The shown persons 9A, 9B...

Abstract

Provided is a robot system that performs control to decelerate or stop the operation of a robot when it is determined that there is a person within a predetermined distance from the robot, and that does not readily reduce the productivity of work. The robot system is characterized by including a robot configured to operate in cooperation with a person, a specifying section configured to specify aperson present in a region at a predetermined distance from the robot, and a control section configured to decelerate or stop the operation of the robot when the presence of the person in the region is specified by the specifying section. The control section changes the distance based on a result of specifying the person by the specifying section.

Description

technical field [0001] The present invention relates to robotic systems. Background technique [0002] A human-robot collaborative robot is a robot that shares a common workspace with humans and performs operations in coordination with humans. [0003] For example, Patent Document 1 discloses an information processing device that includes: a first holding unit that holds personal information; a second holding unit that holds work process information; a measurement unit that acquires measurement data for identifying individuals; An identification unit identifies an individual based on measurement data and personal information; a management unit manages work information including personal information of the identified individual and work process information corresponding to the individual; and a control unit controls the robot based on the work information. [0004] Among them, the identification means for identifying a person detects a person based on the measurement data, b...
