Example calibration program¶
This robot-camera calibration example program requires the Pickit URCap plugin to be installed in your robot. For installation instructions of both the URCap plugin and the example programs, please refer to the URCap installation and setup article.
In the initialization screen, select Program robot and then Load program. Navigate to the
pickit_samples/robot_camera_calibration folder and open the
If you want to perform calibration once or infrequently, you don’t need to use this example program. You can teach the calibration poses manually using free-drive and the Collect current pose button in the calibration wizard of the Pickit web interface.
Multi poses calibration¶
The program starts by opening a pop-up message, informing that multi-poses calibration will be carried out. Before running the program, the user must have the Calibration page of the Pickit web interface open. If this is not the case, it is notified by a pop-up message. Otherwise, the following sequence is repeated five times:
Moves the robot to a waypoint.
MoveJcommands are specified with respect to the tool flange (as opposed to the TCP).
While teaching the waypoints, it is recommended to have the Calibration page open in the Pickit web interface, where the user can verify whether the calibration plate is visible.
This program is a template, and the waypoints are not set. They must be taught by the user since they depend on the physical environment and location of the calibration plate. Refer to the multi-poses calibration article for guidelines on how the five waypoints should be taught.
Sends Pickit a calibration request, through the command
Find calibration plate.
In the Calibration page, the user can follow the progress of calibration.
Single pose calibration¶
For single pose calibration, the program consists of one single calibration request.
