 4. Cleaned up the MJCF file as follows:
     - Added option: `<option integrator="implicitfast"/>`.
-    - Replaced `type="mesh" contype="0" conaffinity="0" group="1" density="0" rgba="0.75294 0.75294 0.75294 1"` with `class="visual"` and add the class to defaults.

     - Added position actuators with joint limits on joints 2, 4, and 6.
     - Added keyframes for "home" and "retract".
 6. Added `scene.xml` which includes the robot, with a textured groundplane, skybox, and haze.

 Do not include the Robotiq mechanical coupling used in arms such as the UR and Franka since for the Kinova Gen3, it is built into the end effector interface. Specifically, if using Menagerie's `robotiq_2f85`, the "base_mount" link (mechanical coupling) should be excluded. Instead, the "base" link should be directly mounted at pose `pos="0 0 -0.06149039" quat="0 -1 1 0"` like so:
