Control system, control method, and control unit
A control system ( 1 ) includes: a control device ( 100 ) that controls a robot ( 200 ); a three-dimensional sensor ( 300 ) that acquires positional information of a worker and the robot ( 200 ), which are included in a viewing-field area in a three-dimensional space; and a support device ( 400 ) that provides a user interface ( 411 ) for virtually setting a cooperation region in which the worker and the robot ( 200 ) are allowed to work. The control device ( 100 ) controls stopping or the speed of the robot ( 200 ) on the basis of whether or not the position of the worker or the robot ( 200 ) calculated on the basis of the positional information is included in the cooperation region, which is set by using the user interface ( 411 ), as well as the relative positional relationship between the worker and the robot ( 200 ) calculated on the basis of the positional information.
1. A control system, controlling a robot, the control system comprising:
a control device, controlling the robot;
a three-dimensional sensor, acquiring position information of a worker and the robot comprised in a viewing-field area in a three-dimensional space; and
a support device, providing a user interface for virtually setting a collaborative work region in which the worker and the robot are allowed to work,
wherein the support device provides a user interface for setting a control content of the robot in accordance with a relative position relationship between the worker and the robot,
wherein the control device controls stopping or a speed of the robot based on whether a position of the worker or the robot calculated based on the position information is comprised in the collaborative work region, the control content and the relative position relationship between the worker and the robot calculated based on the position information.
2. The control system according to claim 1 , wherein the control device controls the stopping or the speed of the robot based on whether the worker or the robot crosses a virtual boundary virtually provided at an end of the collaborative work region.
3. The control system according to claim 2 , wherein the virtual boundary is switched in accordance with whether the position of the robot is comprised in the collaborative work region.
4. The control system according to claim 3 , comprising an projector for visually embodying the virtual boundary in a workspace.
5. The control system according to claim 2 , comprising an projector for visually embodying the virtual boundary in a workspace.
6. The control system according to claim 1 , wherein the control device controls the stopping or the speed of the robot based on whether an object comprising the worker or the robot enters the collaborative work region from a worker side or whether the object enters the collaborative work region from a robot side.
7. The control system according to claim 1 , wherein the support device provides a user interface for setting a plurality of types of regions comprising the collaborative work region as regions where the worker and the robot respectively work.
8. The control system according to claim 1 , wherein the support device provides a user interface for virtually setting the collaborative work region based on an image corresponding to the viewing-field area in the three-dimensional sensor.
9. The control system according to claim 1 , comprising a control device forbidding control of the stopping or the speed of the robot by the control device based on a position of a workpiece related to a work.
10. A control method for controlling a robot, wherein a collaborative work region where a worker and the robot are allowed to work is virtually set by a user interface, wherein a control content of the robot is set by a user interface in accordance with a relative position relationship between the worker and the robot,
the control method comprising:
a step of controlling the robot; and
a step of acquiring position information of the worker and the robot comprised in a viewing-field area in a three-dimensional space,
wherein the step of controlling the robot comprises a step of controlling stopping or a speed of the robot based on whether a position of the worker or the robot calculated based on the position information is comprised in the collaborative work region and the relative position relationship between the worker and the robot calculated based on the position information.
11. A control unit, controlling a robot, the control unit comprising:
a control device, controlling the robot; and
a setting support tool, providing a user interface for virtually setting a collaborative work region in which a worker and the robot are allowed to work,
wherein the setting support tool provides a user interface for setting a control content of the robot in accordance with a relative position relationship between the worker and the robot,
wherein the control device controls stopping or a speed of the robot based on whether a position of the worker or the robot calculated based on position information acquired by a three-dimensional sensor is comprised in the collaborative work region, the control content and the relative position relationship between the worker and the robot.
