This model simulates a six-degree-of-freedom Stewart platform. The position and orientation of the platform is determined by the lengths of six legs. Each leg comprises a linear actuator and five rotational degrees of freedom. The model is constructed from components in the Modelica.Mechanics library. The Wolfram Language is used to plan the 3D geometry of the model, and to produce custom visualizations of simulation results.

To simulate the model and view a 3D animation of it, follow the steps below:
The automatically generated animation shows the Stewart platform following a prescribed test trajectory:
See below for more advanced custom visualizations.
Use the Wolfram Language to plan the 3D geometry of the Stewart platform and solve the inverse kinematics problem to plan the motion of the platform:
