Abstract
A robot controller comprising a processor that is configured to execute computer-executable instructions so as to controls a robot including an arm capable of moving at least one of a target object and a discharger capable of discharging a discharge object to the target object, wherein the processor is configured to use a first position based on a jig removably attached to the discharger to generate teaching information on a position of the arm.
Claims4
A robot controller comprising:
- a processor configured to execute computer-executable instructions to control a robot, the robot including an arm configured to move a discharger, the discharger being configured to discharge a discharge object to the target object,
- wherein the processor is configured to:
- receive information that a jig has been attached to the discharger, the jig being provided with a marker which indicates a position of landing of the discharge object;
- acquire an image captured by an imager, the image including the marker;
- calculate a position of the marker as a first position, the position of the marker being in the robot coordinate system, and the position of the marker being calculated based on the image;
- calculate a relative positional relationship between the position of the discharger and the position of the arm, the positional relationship being based on first correspondence information stored in advance and the first position, the first correspondence information being information representing a relative positional relationship between a position of the discharger and a fixed position of the marker when the jig is in a position attached to the discharger.

A robot system comprising:
- a robot including an arm, the arm being configured to move a discharger, and the discharger being configured to discharge a discharge object to a target object;
- a jig provided with a marker, the marker indicating a position of landing of the discharge object, the marker being provided in a position on the jig that is farthest away from a discharging surface of the discharger in a discharging direction;
- an imager configured to capture an image including the marker;
- a control device including a processor, the processor being configured to execute computer-executable instructions to control the robot,
- wherein the processor is configured to
- calculate a position of the marker as a first position, the position of the marker being in a robot coordinate system, the position of the marker being based on the image;
- calculate a relative positional relationship between the position of the discharger and the position of the arm based on first correspondence information and the first position, the first correspondence information being stored in advance, and the first correspondence information being information representing a relative positional relationship between a position of the discharger and a fixed position of the marker when the jig is in a position attached to the discharger.
