+
+## Overview
+
+This package contains a simplified robot description (MJCF) of the [Stanford TidyBot](https://tidybot.cs.princeton.edu) developed by Jimmy Wu and collaborators from the [Interactive Perception and Robot Learning Lab](https://iprl.stanford.edu) at Stanford University.

+
+## MJCF Model
+
+* The mobile base MJCF was created from a CAD model of the base.
+* The Kinova Gen3 MJCF is taken from Menagerie. See [kinova_gen3](../kinova_gen3/).
+* The Robotiq 2F-85 MJCF is taken from Menagerie. See [robotiq_2f85](../robotiq_2f85/).

+## License
+
+The TidyBot base is released under an MIT License. The Kinova Gen3 and Robotiq 2F-85 MJCFs retain
+their original licenses. For more information, see the [LICENSE](LICENSE) file.
