Status Codes and Troubleshooting

Mech-Vision is not started, or the project is not open

Autoload Project has not been set for the project.

Internal communication error, or another project with the same name exists, leading to failed registration of the Mech-Vision project.

Make sure that Mech-Vision is started and that the project is open.

Make sure that Autoload Project has been set for the project.

Make sure that no projects with the same name exist, and try to restart Mech-Vision.

The Mech-Vision project called has been successfully executed, but the “poses” port has empty output. Possible reasons include exceedingly high confidence threshold for instance segmentation, no matched object in the scene, improper ROI settings, low point cloud quality, improper filtering settings, etc.

The “Procedure Out” Step of the Mech-Vision project does not contain the “poses” port. The possible cause is that the Port Type parameter is set to “Custom”, but the “poses” key is not included.

Check the data flow of the Mech-Vision project by going up from the “poses” port of Step “Procedure Out”.

Check the Port Type parameter and the included keys of the “Procedure Out” Step.

The Mech-Vision project called has been successfully executed, but there is no point cloud in the 3D ROI.

Please check the ROI settings in the Step that sets the 3D ROI on the point cloud. For some projects, this error code can be used to determine whether the bin has been emptied or whether the bin has not been moved to a proper position. So, this error is not necessarily a project execution error.

The pose data sent by command 101 does not consist of 6 numbers. The robot pose is a 6-axis robot pose by default. If the robot is a 4-axis or a 5-axis robot, please fill the remaining fields with 0.

Check the client interface program. The robot pose data sent by command 101 should consist of 6 numbers.

When the Mech-Vision project is still running, the client interface program calls command 101 again to try to trigger the same Mech-Vision project.

Mech-Vision allows concurrent running of multiple projects, but one Mech-Vision project cannot be started again when it is still running.

Check the client interface program and make sure the Mech-Vision project number is correct.

Check the client interface program and see if the program triggers the same Mech-Vision project twice in a short time.

This error usually occurs in projects in which the Mech-Vision result forms a robot motion path (such as gluing applications).

The number of poses and number of labels output from the preceding Steps of Step “Procedure Out” do not match.

Check the poses and labels in the data flow of the Mech-Vision project. Troubleshoot the reasons for the inconsistency between the number of poses and labels.

The project number set in the parameter of command 101 does not exist in the project list of Mech-Vision.

Check if the corresponding Mech-Vision projects all have Autoload Project checked.

Check the client interface program and make sure command 101 has the correct project number in its parameter.

The parameter recipe number in command 103 does not have the corresponding recipe set in the Mech-Vision project.

Check if the Mech-Vision project has the parameter recipe to be set.

Check if the client interface program correctly calls command 103.

The client interface program calls command 103 to set the parameter recipe, but there is no parameter recipe set in the Mech-Vision project.

Check the parameter recipe settings in the Mech-Vision project, and ensure the parameter recipes and their numbers are correct.

If the project does not require switching parameter recipes, please do not call command 103.

The connection between Mech-Center and Mech-Vision is not established.

Please check Mech-Vision’s log for relevant error messages.

The Mech-Vision project has a runtime error with Mech-Vision error code CV-Exxxx or has other errors for which Mech-Center does not have analyses. When such an error occurs, the Mech-Vision project is terminated without finishing execution.

Check the error message in Mech-Vision and modify the Mech-Vision project if necessary.

The label(s) in the vision result from Mech-Vision is not INT data. When using the standard interface, string labels should be mapped to integer labels using Step “Label Mapping”, otherwise this error will occur.

Check the data flow in Mech-Vision, if the labels input to Step “Procedure Out” are not integers, please map the labels to positive integers using Step “Label Mapping”.

The client interface program calls command 101 to trigger the Mech-Vision project. In the command’s parameter, the number of the expected vision points output exceeds the data length of the interface.

The data length can be set in Toolkit ‣ Robot and Interface Configuration in Mech-Vision. Please set the max number of poses sent each time under Advanced Settings. Range: [1, 30].

Make sure the parameter expected number of vision points is smaller than the setting above.

After calling command 102 to obtain the Mech-Vision result and the timing has started, the Mech-Vision project did not finish execution within the specified time.

The timeout period can be set under Advanced Settings of Robot and Interface Configuration in the deployment settings of Mech-Vision. The default timeout period is 10 seconds.

Check the client interface program. A delay operation can be added before calling command 102.

For a Mech-Vision project that takes a long time to execute, the timeout period can be set longer in the deployment settings.

The client interface program did not call command 101 to start the Mech-Vision project but went on to call command 102 to try to get the vision result.

Command 102 has already been called to obtain all the vision targets and the cache is cleared, but command 102 is called again.

Check the client interface program and make sure the project number specified by command 102 is correct.

Check the client interface program. If the parameter value is 1, then all vision targets are transmitted. Keep calling command 102 will lead to this error.

The client interface program calls command 501 to try to input object dimensions to the Mech-Vision project, but the Mech-Vision project does not have a “Read Object Dimensions” Step.

Check the Mech-Vision project and make sure it has a “Read Object Dimensions” Step.

The client interface program calls command 501 to try to input object dimensions to the Mech-Vision project, but the dimension values are invalid (zero or negative values).

Check the client interface program and make sure command 501 passes valid dimension values (positive real numbers).

After the client interface program calls command 110, in the returned data, the number of poses and number of items of a custom data type do not match. A custom data type refers to data input to a port other than PoseList and LabelList of Step “Procedure Out” in the Mech-Vision project. Possible cases include:

Suppose the number of poses input to Step “Procedure Out” is N. It is required that any custom data port (data other than poses and labels) either has 1 item or N item. Otherwise, this error will be raised.

Please check the data flow in the Mech-Vision project.

When the client calls command 105 to obtain the result of the Mech-Vision “Path Planning” Step, the waypoint type parameter in command 105 has a wrong value. This parameter can only be set to 1 or 2.

Check the client interface program. The value of the waypoint type parameter in command 105 should be 1 or 2.

The path planning tool in Mech-Vision failed to plan a path for any of the vision points in the vision result, and not all reasons for plan failures of the vision points are the same. (If the planning failed on the vision points for the same reason, the corresponding error code for such a reason will be raised)

In the corresponding Mech-Vision project, open the path planning tool in the “Path Planning” Step, and check the plan history for the specific reasons for plan failures.

The path planning tool failed to calculate robot JPs for a waypoint.

When the path planning tool is planning the robot path, a robot singularity is encountered.

Check where the singularity is in the path planning tool and modify the corresponding poses or parameters.

The path planning tool found that the robot cannot reach a waypoint by linear motion.

Modify the waypoint in the path planning tool or add intermediate points.

Change the motion type to joint motion.

In Mech-Viz, “Scene objects” is set to the “Bin” model, and “Set effective range for pose” is selected.

When the above configuration is used, if the vision point returned by Mech-Vision is outside the bin model, Mech-Viz will assume that the robot cannot pick up an object according to this vision point, and the path planning tool will report an error. This status code corresponds with internal error code MP-E0010.

Check if the bin is away from the original position. If so, move the bin back.

Check if the workobjects are in a small number and close to the bin walls. If so, move the workobjects away from the bin walls.

Check the size and pose of the “Bin” model in Mech-Viz. If they are different from the size of pose of the bin in use, change the parameter values according to those of the bin in use.

The path planning tool detected robot self-collision and the path planning failed.

Check the corresponding waypoint in the path planning tool.

“Vision Move” in the Path Planning Step failed to receive any pose.

Check the dataflow before the Path Planning Step in the Mech-Vision project.

The “Capture Images from Camera” Step did not complete execution within the timeout period set by “Timeout waiting for capture completion(s)”.

Select “Robot Communication Configuration” on the toolbar. Click “Next” and then click “Advanced Settings”. Check the value of “Timeout waiting for capture completion(s)”, which is visible only after “Return ‘1102: Successfully triggered’ after the capture” is selected.

Compare the value of “Timeout waiting for capture completion(s)” and the execution time of the “Capture Images from Camera” Step. If the value of “Timeout waiting for capture completion(s)” is smaller than the execution time of the “Capture Images from Camera” Step, adjust the value of “Timeout waiting for capture completion(s)”.

Mech-Viz is not started.

Multiple Mech-Viz windows are opened under the developer mode.

Make sure Mech-Viz is started.

Uncheck Developer mode in Settings ‣ Options and restart Mech-Viz.

When a Mech-Viz project is still running, command 201 is called to trigger the Mech-Viz project.

Make sure the client interface program does not call twice command 201 to trigger the same Mech-Viz project within a short time.

Step “check_look” does not find any vision result and takes the 2nd exit (“no result”). And the project ends.

If necessary, add additional Steps to the “no result” exit of Step “check_look”.

Check if the workobjects have all been picked away.

Check the Mech-Vision project to see if settings such as ROI settings, instance segmentation confidence threshold, etc. are proper.

Mech-Viz failed to calculate robot JPs for a waypoint.

Mech-Viz failed to plan a path for any of the vision points in the vision result, and not all reasons for plan failures of the vision points are the same. (If the planning failed on the vision points for the same reason, the corresponding error code for such a reason will be raised)

Check the plan history in Mech-Viz.

The error may be reported by a Mech-Viz error code MP-Exxxx or may not yet have an analysis by Mech-Center. An error occurred when the Mech-Viz project was running and the project has been terminated.

Check the pop-up window or logs of Mech-Viz.

An error with Mech-Viz error code MP-E0007 occurred when running the Mech-Viz project.

The client program calls command 206 to obtain the DO signal list that controls the tool (sectioned suction cups, array gripper, etc.), but in the Mech-Viz project, no DO signal list has been configured.

Check whether there is a Set DO List Step that follows the Vision Move Step. In the parameters of the Set DO List Step, under “Receiver”, “Standard Interface” should be checked.
