To learn how to use MBsysPad, follow the PendulumSpring tutorial available here.

Why a specific version for MacOS ?

Robotran uses Java3D for the 3D views. Java3D 1.5 does not work on MacOS anymore. If you want to use Robotran on MacOS with 3D views, you must try the specific link which uses Java3D 1.6 (still experimental).

Download PyRobotran

Workspace templates

Workspace templates define the folder structure of a new project and determine which files are copied automatically to the project folder at project creation. In this way, pre-written files are available for user function (userfctR subfolder) and main function (dataR subfolder). Python specific templates were defined and can be installed as follows:

This will add two new "Workspace type" when creating a new project in MBsysPad:

  • PythonTemplate: This template defines a project folder with python template files for performing a direct dynamics analysis
  • PythonTestTemplate: This option is usefull if you wan’t to use PyRobotran after having used MBsysLab (Matlab). This will install all required files for performing a simulation in Python and in Matlab. You can compare the python solution and the matlab solution by running the PyMa file.
