We designed Stretch's hardware to be easily extended. You can make your own tool and attach it to the wrist to creatively expand what Stretch can do. Your tool can also use Dynamixel X-series servos from Robotis via the provided TTL bus.
In this tutorial, we provide examples of some of the tools that we've created. We've released them with a permissive Apache 2.0 license, so you're free to use them as you wish. We hope they'll inspire you to create your own.
We also include URDF and mesh files for many of the tools in their stretch_description folder. See the Stretch ROS documentation for guidance on integrating these tools into your robot model.
We'd love it if you shared your creations with the community. We recommend you create a GitHub repository for your own tools and then post an announcement to the forum to let people know about it.
