Control device, robot, and robot system

A control device comprising:

• a control portion which is configured to operate a robot including a movable portion capable of being provided with an end-effector that works with respect to a target;
• and
• a receiving portion which is configured to receive an input command and to output a signal based on the received input command to the control portion,
• wherein the control portion is capable of allowing the robot to perform two or more works selected from a first work of performing calibration between a coordinate system of a first imaging portion having an imaging function and a coordinate system of the robot, a second work of performing calibration between a coordinate system of a second imaging portion having an imaging function and a coordinate system of the robot, a third work of calculating a posture of a virtual standard surface that corresponds to a work surface on which the robot works, a fourth work of calculating a distance between the first imaging portion and a standard point of the robot, and a fifth work of calculating a distance between the end-effector and the standard point, based on one input command received by the receiving portion.
