Manipulator system

1. A manipulator system configured to perform a work to a workpiece being moved by a moving device, comprising:

a robotic arm, having one or more joints and to which a tool configured to perform the work to the workpiece is attached;

a first imaging means configured to image the workpiece, while following a movement of the workpiece;

a second imaging means fixedly provided in a work area to image a situation of the work to the workpiece;

a displaying means configured to display, to a worker, a first image imaged by the first imaging means and a second image imaged by the second imaging means;

an operating device configured to be operated by the worker and receive a manipulation input, the worker operating the operating device to perform manipulation of the robotic arm while viewing the first image and the second image displayed by the displaying means; and

a control device configured to:

detect a moving amount of the workpiece being moved by the moving device;

generate a tracking-controlled operation that is an operation of causing the robotic arm to follow the workpiece according to the detected moving amount of the workpiece; and

add, to the tracking-controlled operation, a manipulation-controlled operation that is an operation of the robotic arm according to an operating instruction corresponding to the manipulation input to the operating device so as to control the robotic arm, such that the robotic arm performs the manipulation-controlled operation while performing the tracking-controlled operation.

2. The manipulator system of claim 1 , wherein the manipulator system performs the work to the workpiece being moved by a conveyor or a positioner provided with one or more driving shafts, and

wherein the control device detects the moving amount of the workpiece based on a driving amount of the one or more driving shafts of the conveyor or the positioner.

3. The manipulator system of claim 1 , wherein the first imaging means is attached to a tip end of the robotic arm.

4. The manipulator system of claim 1 , wherein the displaying means switchingly displays the first image imaged by the first imaging means and the second image imaged by the second imaging means.

5. The manipulator system of claim 4 , wherein the displaying means switchingly displays the first image of the situation of the work to the workpiece imaged by the first imaging means while following the movement of the workpiece, and the second image of the situation of the work to convey the workpiece between a given position and the moving device in the work area, imaged by the second imaging means.

6. The manipulator system of claim 1 , wherein the first imaging means includes a plurality of fixed cameras fixedly provided in the work area and arrayed along the moving direction of the moving device, the first image being one of a plurality of first images captured by the plurality of fixed cameras, and

wherein the displaying means switchingly and sequentially displays the plurality of first images imaged by the plurality of fixed cameras so as to follow the movement of the workpiece.

7. The manipulator system of claim 1 , wherein the control device detects the moving amount of the workpiece, which is moved by the moving device, based on a driving amount of the moving device, and controls the operation of the robotic arm based on the operating instruction of the operating device.

8. The manipulator system of claim 1 , wherein the control device controls the operation of the robotic arm based on a third moving amount of a position and posture at a tip end of the robotic arm, the third moving amount being a sum of a first moving amount of the position and the posture at the tip end of the robotic arm and a second moving amount of the position and the posture at the tip end of the robotic arm, the first moving amount being a moving amount by which the robotic arm follows the workpiece according to the moving amount of the workpiece, the second moving amount being a moving amount by which the robotic arm operates based on the operating instruction of the operating device.

9. A manipulator system configured to perform a work to a workpiece being moved by a conveyor, comprising:

a robotic arm, having one or more joints and to which a tool configured to perform the work to the workpiece is attached;

a first camera configured to image the workpiece, while following a movement of the workpiece;

a second camera fixedly provided in a work area to image a situation of the work to the workpiece;

a display configured to display, to a worker, a first image imaged by the first camera and a second image imaged by the second camera; and

a joystick configured to be operated by the worker and receive a manipulation Input, the worker operating the joystick to perform manipulation of the robotic arm while viewing the first image and the second image displayed by the display; and

a processor programmed to:

detect a moving amount of the workpiece being moved by the conveyor;

generate a tracking-controlled operation that is an operation of causing the robotic arm to follow the workpiece according to the detected moving amount of the workpiece; and

add, to the tracking-controlled operation, a manipulation-controlled operation that is an operation of the robotic arm according to an operating instruction corresponding to the manipulation input to the joystick so as to control the robotic arm, such that the robotic arm performs the manipulation-controlled operation while performing the tracking-controlled operation.
