ExoMy is the 3D printed rover developed at the European Space Agency.
The rover is inspired by ExoMars and serves as an educatial tool to learn about mechanics, 3D-printing, electronics, software and rovers. It features six steerable wheels on a triple bogie suspension which mimics the locomotion capabilities of ExoMars. A camera in the head furthermore allows teleoperation and for very enthusiastic people even computer vision.
ExoMy can be controlled using a web interface for smartphones, tablet or laptops as well as a standard gamepad. The robust design allows kids to playfully experience the fascination of a planetary explorer.
ExoMy features a triple bogie configuration as found on ExoMars. The 6 steerable wheels allow ExoMy to crab, turn on the spot and drive a generic ackerman.
A Raspberry Pi camera integrated in the head allows teleoperation and the implementation of computer vision algorithms.
The hat and mouth can be easily exchanged and customized. This allows you to make your very own ExoMy a complete one off. Advanced customizations are also no problem as all hardware and software files are open source.
ExoMy uses off the shelve components and 3D printed parts. Everyone with access to a 3D printer and basic tools can build ExoMy. This initial version costs around 500€ to build. It is however possible to change certain parts (camera, raspberry pi, servos) for more afforable parts to lower the total cost to around 200 €.
The software is completly written in Python with ROS and is completely open source.
A web interface is available to control ExoMy from a smartphone, laptop or tablet.
Download the files and the software. Then head over to the wiki for detailed instructions on how to build it.
ExoMy was developed at the Planetary Robotics Laboratory by Maximillian Ehrhardt, Miro Voellmy, Levin Gerdes and Shanker Ganesh Krishnamoorthy. We are always happy to hear your feedback and interest in the project. You can contact us via email or create an issue here on GitHub.
