-  <description>This experiment loads the Husky robot from Clearpath Robotics in the Holodeck environment.
-        If the user starts the experiment, the Braitenberg vehicle network is executed
-        and the robot will turn around itself in place, until the camera detects a red color. Then,
-        the robot will move towards the colored object. In this experiment, the user can interact
-        and change the color of both screens by clicking on them with the right mouse button.</description>
