Mech-Viz 1.8.2 Release Notes

This document introduces the new features, improvements, and resolved issues of Mech-Viz 1.8.2.

New Features

Added “Translational Relaxation” in the Workobject Configuration

Once the translational relaxation is applied, the end tool will incrementally translate along the X-axis or Y-axis of the pick point, attempting picks at different positions to avoid collisions.

Added Cylinder Geometry Type in the “Predefined Pallet Pattern” Step

  • Added “Horizontal cylinder” to the geometry type for palletizing, and the pallet pattern can be set to Pyramid or Staggered.

  • Added “Vertical cylinder” to the geometry type for palletizing, and the pallet pattern can be set to Auto layout, Aligned, or Staggered.

Support High-Accuracy UR-like Robot Configuration

Added the high-accuracy UR-like robot configuration, which can improve the accuracy of UR-type robots significantly. The complete DH parameters, which are calibrated by the laser tracker at the factory, are filled into the new configuration to improve the robot accuracy.

Support Robot Configuration with Offset at the Flange

Support the robot configuration with offset at the flange. Panasonic TM-1800 uses this configuration.

Improvements

Multiple Parameters Can Be Selected in the “Reset” Step

Multiple Steps and their corresponding parameters can be selected in the “Reset” Step. Then the Steps and their parameters can be reset with one “Reset” Step.

Improved “Plan History”

  • Once an entry in the plan history that caused collision is selected, the collision point cloud will flash in the 3D simulation area, helping you to locate the collision quickly.

  • The visualization of the tool is added to the plan history animation so that you can observe the motion path of the tool in detail.

Migration of Display Settings to 3D Simulation Area

The following content has been added to the 3D simulation area:

viz 182 icon 1

Text and axis size settings

viz 182 icon 2

Reference frame visibility in the 3D simulation area

viz 182 icon 3

Visibility of the components in the vision result

viz 182 icon 4

Vision pose color legend

Others

  • When palletizing in the “Multiple at once” mode, boxes with different pick point labels will no longer be grouped in the same group.

  • Added horizontal cylinder and vertical cylinder workobject models, and supported collision detection.

  • Removed the “Backup” option from the context menu of the project list.

  • The sequence of Steps was adjusted according to the frequency of their use, and the Frequently-Used Step category was added.

  • Enabled dragging and dropping multiple robot models to the robot model library at a time.

  • The rotational symmetry of the depalletizing vacuum gripper can only be set to “None” or “2-fold.”

  • The “Skip Execution” parameter was removed from the “Basic Non-Move” parameter group of most Steps and retained only in the “Branch by Msg” and “Check DI” Steps. In addition, the parameter was improved and renamed as “Step Behavior During Simulation.”

  • The “Mixed Pallet Pattern” Step was renamed as “Mixed Case Palletizing.”

Resolved Issues

The following issues have been resolved in Mech-Viz 1.8.2:

  • When the singularity detection threshold was set too high or singularity detection was not performed, the singularity detection may have missed detections during the rotational movements of the robot.

  • Due to the incorrect introduction of point cloud removal logic based on the Binvox workobject model, planning speed was slowed down.

  • The solution selection strategy of “Minimum difference between tool and vision pose” may not take effect.

  • The connection status of the robot may be incorrect.

  • The robot model may not be displayed.

  • The “Tag” parameter value of the “Set Tag for Branch” Step may not match the “Out Port Count” parameter value of the “Branch by Tag” Step.

  • Executing the “Update Held Workobject” Step may result in the loss of updated workobject labels.

  • During the execution of the “Vision Continue Palletizing” Step, if the relevant vision service failed to recognize the box, it may result in an error.

  • Under Master-Control, consecutive execution of the “Set DO” and “Wait” Steps may lead to DO errors.

  • After completing the “Multi Pick Palletizing” Step in the current stacking round, failure to reset before proceeding to the next stacking round may result in collision detection omissions.

Before You Upgrade

  • Since the rotational symmetry of the depalletizing vacuum gripper can only be set to “None” or “2-fold” in version 1.8.2, the previous rotational symmetry settings other than the above two options will be reset to “None” in the new version software.

  • In the earlier versions of software, when a “Vision Move” Step with the “Reuse Vision Result” parameter selected was used in conjunction with the “Is Vision Result Used Up” Step, the “Used up” exit port of the “Is Vision Result Used Up” Step would be taken if all target objects were picked. In version 1.8.2, the “Other failures” exit port of the “Vision Move” Step will be taken instead.
