Mech-Viz 1.7.4 Release Notes

This topic introduces the resolved issue in Mech-Viz 1.7.4.

Improvements

Added Region-Specific Software License Control

The software license is updated to add the restriction of using the software in regions where the software is purchased.

In Mech-Viz 1.7.4, you can go to Help  About to check the software license and region restrictions.

Removed “System Language” from the Software “Language” Option

From Mech-Viz 1.7.4, “System Language” has been removed from the “Language” option (Settings  Options  Common  Language) of the software. If the operating system language of the computer is not a language supported by the software (English, Simplified Chinese, Japanese, or Korean), the default language when the software is installed for the first time is English.

This improvement has resolved the following two issues:

  • The link redirection failed and Step names were displayed abnormally in the software when the operating system language of the computer was not a language supported by the software.

  • The language pack could not be loaded successfully according to the operating system language of the computer.

Others

  • The “Palletizing” parameter for Palletizing Steps was renamed to “Pallet position”.

  • The information about rows in a box group, box_group_row_count, was added to the log and plan_result related the “Vision Move” Step.

Resolved Issues

Mech-Viz 1.7.4 has fixed the following issues:

  • The “Delete Object” option in the context menu of the simulation area was not been disabled during project simulation or running.

  • When the workobject rotational symmetry and tool rotational symmetry settings are applied at the same time, an error might occur in the workobject rotational symmetry attempt.

  • When there was not a move-type Step before the “Branch by Msg” Step, the Out Port When Skip setting would not take effect.

  • The vision result labels were lost after reusing vision results.

  • Drag any log entry might cause the software to crash.

  • After enabling “Limit Total Count” in the “Vision Move” Step, not all possible grouping results were provided.

  • The suction cup DO that was planned by using the “Vision Move” Step might be incorrect.

  • When the “Vision Continue Palletizing” Step was used to match the pallet pattern, the orientation of the pallet might be incorrect.

  • When the workobject model is a custom model, an collision might be missed during the collision detection.

Mech-Viz 1.7.2 Release Notes

This document introduces the new features, improvements, and resolved issues of Mech-Viz 1.7.2.

Improvements

Simulating All Planned Waypoints

In previous versions, if “Send Waypoint” was not selected for a move-type Step, the corresponding waypoint would only be involved in the path planning, and the simulated robot would not move to this waypoint.

In Mech-Viz 1.7.2, the simulated robot will move along all planned waypoints by default.

If you want to keep the previous setting, please adjust it in Settings > Options > Basic settings.

STL and DAE Source Files Will Be Retained after Robot Exporting

In previous versions, the STL and DAE source files of the robot would be deleted while the robot was exported.

In Mech-Viz 1.7.2, the STL and DAE source files of the robot will be retained after the robot is exported.

Removed the “Side Vacuum Gripper” Option

In previous versions, the “Side vacuum gripper” option can be configured in the “Vision Move” Step and “Tools”. This feature was used for depalletizing applications in which the side vacuum gripper was used as the end tool.

From Mech-Viz 1.7.0, the “Depalletizing vacuum gripper” option covers all features of the “Side vacuum gripper”.

Therefore, the “Side vacuum gripper” option is removed in Mech-Viz 1.7.2. Please re-configure the “Depalletizing vacuum gripper” option if you used the “Side vacuum gripper” option previously.

Supported More Euler Angle conventions

In previous versions, only 5 common types of Euler angles were supported. In Mech-Viz 1.7.2, another 13 types of Euler angles are supported as well.

Removed “Run in Advanced on Planned” Parameter from “Branch by Msg” Step

In Mech-Viz 1.7.2, the “Run in Advanced on Planned” parameter in the “Branch by Msg” Step has been removed.

Updated Soft Limit Algorithm for SCARA Robots

In previous versions, there was an error in the soft limit algorithm for SCARA robots, which made it unable to save the soft limits of J3. In Mech-Viz 1.7.2, this issue has been fixed, and you will need to adjust the soft limits of J3 manually.

Resolved Issues

Mech-Viz 1.7.2 has fixed the following issues:

  • The transparency status of “Tools” set in the “Resources” panel was not consistent with that of the tool in the simulation area.

  • The “Set effective range for pose” feature for bins in “Scene objects” did not take effect.

  • The software might crash when the “Smart Obstacle Avoidance” feature was used.

  • When the “All Waypoints in One Move” feature was used in the “Move by List” Step, certain waypoints might be missed.

  • When the box dimensions were adjusted in the “Predefined Pallet Pattern” Step, the palletizing sequence would not be adjusted automatically according to the change of the pallet pattern.

  • When the “Mixed Pallet Pattern” Step was used, the box might be palletized on a position that had been occupied by a box.

  • The source Step of the pallet pattern had been selected in “Vision Continue Palletizing”, but a hint saying that no Step was selected popped up.

  • The box depalletizing algorithm considered the gap between suction cups as valid suction cup areas.

  • The output vision result of the box group did not contain labels for each box.

Mech-Viz 1.7.1 Release Notes

This document introduces the improvements and resolved issues of Mech-Viz 1.7.1.

Improvements

Modified the Default “Obstruction Tolerance Distance” in the “Vision Move” Step to 40 mm

In previous versions, the default value of “Obstruction Tolerance Distance” in the “Vision Move” Step was 20 mm, which was too strict for some on-site applications and thus caused Mech-Viz to discard many feasible picking solutions during the planning.

In Mech-Viz 1.7.1, the default value of “Obstruction Tolerance Distance” in the “Vision Move” Step has been modified to 40 mm.

Resolved Issues

The following issues are resolved in Mech-Viz 1.7.1:

Resources - Robot

  • Modifying the soft limits of the robot might cause a crash of the software.

  • There was an error in the visualization model of the FANUC R-2000iC/270F robot.

  • If two “Relative Move” Steps were dependent on each other, the software would enter a dead loop.

  • The “Vision Continue Palletizing” Step might cause a crash.

  • After the “Multi Pick Palletizing” Step was reset, the palletized cartons remained unpalletized.

  • When the robot was not moving, the “Update Held Workobject” Step could not display the model of the held workobject.

  • The “Update Held Workobject” Step might cause a stuck on the software.

  • When the “Classify” Step was in front of the “Vision Move” Step, and the Avoid Picking on Save Workpiece feature was enabled in “Vision Move”, the software might enter a dead loop.

  • When another move-type Step was connected with the Other failures exit port of “Vision Move”, an error message still popped up.

Picking/Placing Planning

  • The “Only Group Complete Row” setting along Y-axis in the multi-pick depalletizing algorithm was not effective.

Other Issues

  • When an unreachable waypoint led to a planning failure in the Plan history panel, the robot tool model could not be displayed correctly.

Mech-Viz 1.7.0 Release Notes

This document introduces the new features, improvements, and resolved issues of Mech-Viz 1.7.0.

New Features

New “Welcome” Interface

After the software is started or a project is closed, a “welcome” interface will be displayed. You can create a new project or open a recent project in the “welcome” interface.

New “Resources” Panel

In Mech-Viz 1.7.0, the original “Scene” and “Tools and Workobjects” functional panels are removed. The resources used in the project are re-organized and aggregated in Resources, which is a new tool to manage the project resources.

The aggregated “Resources” include project, robot, reference frames, tools, floor, scene objects, and model library.

  • Project: Display the project name, project modification status, and the project autoload status.

  • Robot: Display the robot model used in the current project.

  • Reference frames: Aggregate all reference frames in the 3D simulation area.

  • Tools: For creating and deleting tools and managing the existing tools.

  • Workobjects: For creating and deleting the workpiece configurations and managing the existing workpieces.

  • Floor: For adjusting the height of the floor.

  • Scene objects: For creating and deleting scene objects and managing the existing scene objects.

  • Model library: For managing all models used in the project. All models should be imported to the Model Library first and then utilized with other functions.

Added “Set as Active Tool”

The concept “active tool” has been introduced. The tool set as the “active tool” will be used for path planning when the new round of simulation/execution starts.

  • When the project is not simulating or running, right-click the name of the tool in the Resources panel and select “Set as Active Tool” to change the “active tool”.

  • When the project is simulating or running, you can change the “active tool” by using the “Change Tool” Step.

Added Automatic Layout Feature in the “Predefined Pallet Pattern” Step

The “Predefined Pallet Pattern” Step calculates based on the pallet size, dimensions of the carton, gap width, and limitation of the pallet height to generate a pallet pattern with the most cartons and layers, of which the layout of the odd layer and even layer is also appropriate.

Other Features

  • Added “New Project” option in the File menu.

  • Added robot models for ROKAE SR3 and ROKAE SR4 robots, and generated the corresponding special robot configurations.

  • You can select multiple Steps and use the shortcut Ctrl + G to pack them as a Procedure, and you can also use the shortcut Ctrl + Shift + G to unpack the selected Procedure.

  • Added a “Wait Timeout” port to the “Branch by Msg” Step. You can set a timeout period and the Step will take the “Wait Timeout” port to proceed if a timeout occurs.

  • You can save and import the pallet pattern in the offline mode of the “Mixed Pallet Pattern” Step.

  • Added a new feature to specify the direction of the palletized carton in the “Mixed Pallet Pattern” Step.

  • Added a new “Pinwheel 2” pallet type in the “Predefined Pallet Pattern” Step.

  • Added a new feature to adjust the workpiece orientation in the “Predefined Pallet Pattern” Step.

Improvements

Expanded the Robot Model Library

The number of robot models in the online robot model library has increased from 214 to over 600. Most robots from ABB, Denso, FANUC, Kawasaki, KUKA, MITSUBISHI, NACHI, UR, Stäubli, and YASKAWA have been included.

he parameters of robots from ABB, FANUC, Kawasaki, KUKA, NACHI, UR, and YASKAWA have also been calibrated during the model-making process, and therefore the robot parameters are more accurate.

Tool Collision Model in STL format is No Longer Supported

To achieve better performance of the collision detection between the tool and the point cloud, collision models of the tool in STL format are not supported anymore in Mech-Viz 1.7.0. Please refer to Note of the Models for model formats supported in the software.

Improved the Depalletizing Algorithm in the “Vision Move” Step

In Mech-Viz 1.7.0, the depalletizing algorithm in the “Vision Move” Step has been restructured and improved, and the following picking methods are supported.

Single-section vacuum gripper

viz release pallet 1

Multi-section vacuum gripper

viz release pallet 2

Pick a single object

viz release pallet 3

Pick multiple objects in a row

viz release pallet 4

Pick objects in multiple rows

viz release pallet 5

Center of the vacuum gripper coincides with that of the carton

viz release pallet 6

Midpoint of the vacuum gripper’s edge coincides with that of the carton’s edge

viz release pallet 7

Corner of the vacuum gripper coincides with that of the carton

viz release pallet 8

Long edges of objects are parallel to that of the vacuum gripper

viz release pallet 9

Long edges of objects are perpendicular to that of the vacuum gripper

viz release pallet 10

In addition, the software no longer restricts the X-axis of the TCP reference frame to be parallel to the long side of the vacuum gripper and the X-axis of the workpiece pick point reference frame to be parallel to the long side of the carton. There is no coupling between all the above features, and a variety of picking strategies can be configured by modifying the parameters.

Improved the Model Editor

  • A new “Set Frame” feature is added to the Model Editor. With this feature, you can set the origin and the directions of the axes for the reference frame. Therefore, the exported OBJ model can be accurately and quickly installed at the end of the robot flange.

  • The project in Model Editor is saved as M3D file and you do not need to create a folder to save the project.

  • OBJ models exported by Model Editor are compatible with Mech-Viz 1.6.0 and earlier.

Improved the Display Format of Euler Angles

The Euler angles are denoted differently on the teach pendant of different robot brands. For example, ABB uses EX, EY, and EZ; KUKA uses A, B, and C; while Kawasaki uses O, A, and T.

In Mech-Viz 1.7.0, the display formats of Euler angles for some robot brands are integrated in the software. Once a robot is selected, the software will automatically switch the display format of Euler angles to the one corresponding to the selected robot, and the characters used by the robot brand will be displayed in the interface.

Improved Tool Configurations

In Mech-Viz 1.7.0, the tool configuration window is re-organized and improved. The new tool configuration window consists of the tool type options and “Configure control logic” button, and the symmetry configuration parameters have been improved.

Improved Workobject Configurations

The new workobject configuration window in Mech-Viz 1.7.0 aggregated functions related to workobject configurations that were in different locations in the software. The new workobject configuration window provides settings of the rotational symmetry, picking relaxation, and solution selection strategy.

Improved Scene Object Configurations

In Mech-Viz 1.7.0, the interfaces used for creating new scene objects and configuring scene objects are combined, and parameters for setting the effective range for poses have been improved.

Renamed Steps

Starting from Mech-Viz 1.7.0, “Skill” and “Task List” have been renamed to “Step” and “Procedure”. In addition, the names of the following Steps have been updated in Mech-Viz 1.7.0 for easier understanding of the functions. In addition, the format of all Step names have been changed to title-style capitalization.
