a second camera attached to a worker; and

a control device configured to:

control the robot, when part of a work target is blocked from the at least one first camera due to the worker's body, based on an image from the at least one first camera and an image from the second camera, by:

specifying a position of a workpiece or a component,

specifying a skeletal posture of the worker, or

specifying states of the worker;

or

control the robot, when an entirety of the work target appears in an image from the at least one first camera, based on an image from the at least one first camera, by:

specifying a position of the workpiece or the component,

specifying the skeletal posture of the worker, or

specifying states of the worker.

2. A robot control system, comprising:

a robot;

at least one first camera attached or fixed to the robot;

a second camera attached to a worker,

wherein the second camera includes an acceleration sensor; and

specifying states of the worker.

3. A control device, comprising:

a communication interface between a first camera, a second camera, and a robot;

a memory; and

a processor configured to execute a program stored in the memory:

control the robot based on an image of the first camera and an image of the second camera by:

specifying a position of a workpiece or a component,

specifying a skeletal posture of a worker, or

specifying states of the worker;

or

control the robot, when an entirety of the work target appears in an image from the first camera, based on an image from the first camera, by:

specifying a position of the workpiece or the component,

specifying the skeletal posture of the worker, or

specifying states of the worker.
