MATLAB: Does SimMechanics 2.7.1 (R2008a) ship a demo for an inverted pendulum on a moving base

I need an example model or a demo for an inverted pendulum on a moving base in SimMechanics 2.7.1 (R2008a).

SimMechanics 2.7.1 (R2008a) does not ship a demo for an inverted pendulum on a moving base. However, you may use the attached example model that illustrates how to build an inverted pendulum on a moving base using SimMechanics.

MATLAB: How to make SimMechanics Visualization focus on one body in a model in SimMechanics 2.7.1 (R2008a)

The ability for SimMechanics Visualization to focus on one body when there is more than one is not available in SimMechanics 2.7.1(R2008a).

There are two possible workarounds:

1) If there is only one body in the model, you can focus on that body by first clicking on "Fit Machine to View" and then unchecking the SimMechanics->Viewpoint->Enable Automatic Axis Resize option. This will cause the visualization focus to move with the body.

2) If there are multiple bodies in your model, you can manually manipulate the camera object to make it follow a certain body. Attached is an example MATLAB file as well as a modified version of the SimMechanics mech_rolling_sphere demo, which demonstrate this approach. When you run the modified demo model, you will notice the ball will be tracked by the camera. This workaround has been implemented by taking the following steps:

    a. Measure the position of the point to track using a body sensor (in this case the Sphere)
    b. Feed the position using a MATLAB block to the setMachineCamera function
    c. The setMachineCamera function finds the visualization window, gets its camera object and updates it using the body position

More information about the setMachineCamera function can be found in its comments. Note that this approach may be reducing performance of your simulation due to the presence of a MATLAB block in the Simulink model.

MATLAB: Does the Pro/Engineer-to-SimMechanics translator 1.1 for for SimMechanics 2.7.1 (R2008a) work with Pro/Engineer Wildfire 4.0

To have the Pro/Engineer-to-SimMechanics translator 1.1 working with ProE Wildfire 4.0, the Pro/Toolkit registry file should have the following additional line:

 unicode_encoding false

Thus, the registry file would have something similar to:

 NAME SimMechanics
 EXEC_FILE C:\Program Files\MathWorks\proe2sm\bin\win32\pmi_proe2sm.dll
 TEXT_DIR C:\Program Files\MathWorks\proe2sm\text
 STARTUP dll
 UNICODE_ENCODING false
 REVISION wildfire
 END

You can either add this line directly to the existing Pro/TOOLKIT registry file, or else, add this to the proe2sm.dat file that is created when the translator is installed and specify the absolute path of this file in the Pro/ENGINEER configuration file.
