Information

This model is of a LEGO Segway with disturbances, but without any kind of controller to keep it upright. For the model with a controller, open LEGOSegway.LQControl.

Simulation

To simulate the LEGO Segway and view a 3D animation of it, follow the steps below:

Click the Simulate buttom: simCenter

Click the Animate button: animate

In order to get the full experience of this example, you need a desktop Wolfram Language product. A free trial download is available at www.wolfram.com/mathematica/trial/

For the full example, open the accompanying notebook LEGOSegway.nb.
