Using the GOTO Activity

You can create forward, backward, and sideways GOTO activities, edit the activities, and observe the behavior in a simulation.

This task shows you how to:

Before you begin:

  • The manikin and all other resources in your scenario.

  • The manikin must have at least one human task defined.

Note: Activate Use postures from Motion Capture for GOTO activity in Me > Preferences > App Preferences > Simulation Ergonomics, Ergonomics at Work, Simulation tab. This provides a more natural posture during a walk simulation thus bringing the digital human model closer to the real world.

Creating a GOTO Activity

You can create a forward, backward, or sideways GOTO activity.

  1. Click Create GOTO from the Quick Activity Breadcrumb Trail.
    The status bar stipulates, Modify the walk path or walk options or select another target location, and the dialog box appears with the Walk tab.
  2. From the Walk To Location section, select the requirements.
  3. Click and grab the robot to move the manikin to the required position.


    See Simulation context toolbars.

    See About Human Locations.

    Creating a Human Location.

  4. Release the left mouse when you have the manikin in the required location.
    The walk path appears in the work area with the added spline points.
    Note: After releasing the left mouse, you can still drag the manikin (using the graphic handle) for finer adjustments. If the manikin movement is within 300 mm, the last point does not move and no additional spline points add.
  5. Click OK.

    See GOTO Dialog Box for more information.

Edit Default Options for GOTO Activity

You can edit the default options for the GOTO activity for a manikin.

  1. Double-click the breadcrumb thumbnail in Behavior.

    Important: In the free walk mode, you can start creating a GOTO position with the manikin at a particular point. Now, if you try to fine-tune the position by dragging the graphic handle a bit (forward/backward and others by a distance greater than 300 mm). The walk path contains loops and you have to individually delete the spline points to fix the path.

    See About Sequencing Sequencing.

  2. Double-click the required breadcrumb, Walking to the Engine that has the Create GOTO.
    This opens the breadcrumb.

  3. Click theGoto.1 icon to open the dialog box.

In Sequencing Viewing the GOTO Activity

You can play the GOTO activity and observe the simulation behaviors in Sequencing.

  1. Select the Human Task that has a GOTO activity.

  2. Select Play.
    The walking postures generate based on the walk path before the simulation of the corresponding GOTO starts.
    Note: The starting point of the walk path is dynamic and it depends on the current location of the manikin.
  3. Selecting Play again.
    When pressing Play a second time, it replays the simulation without deactivating the command. A confirms done to verify if the manikin position before the start of GOTO is identical to the position in the step above.
    • If yes, no plannings done and the postures generate in step 2, and uses to replay the simulation.
    • If no, then GOTO is again planned and new defined postures generate that now simulate.

    In this scenario, the length of the walk path is 0 as the starting and ending points of the path are coinciding and there is no initial state.

  4. To reset this, deactivate Play.
