In an exciting initiative aimed at preparing the next generation of space explorers, university students participated in a hands-on training course organized by the European Space Agency (ESA) at its ESTEC technical center in the Netherlands. Over a remarkable four-day workshop, participants faced the exhilarating challenge of programming 3D-printed rovers to navigate a simulated Martian environment.

Thirty engineering and robotics students from 14 ESA member states and Canada were given the programmable ExoMy rovers, sophisticated machines echoing the design of ESA’s future Rosalind Franklin rover, which is set to launch in the coming years. Featuring six wheels, a high-resolution camera, and powered by a Raspberry Pi computer, these rovers were equipped with open-source hardware and software, allowing for easy modifications and innovative enhancements.

According to ESA robotics engineer Marti Vilella Ramisa, the workshop aimed to immerse students in the intricacies of rover design and operation, pushing the boundaries of their technical skills. This unique training experience involved a mix of lectures and practical sessions where students had the chance to debug the rovers’ ROS 2 Robot Operating System code, primarily written in Python.

The workshop kicked off with an overview of robotics, followed by hands-on demonstrations where students remotely controlled their rovers across Mars-like terrains using wireless gamepads. Their work involved not only refining the rovers’ functions but also implementing new locomotion modes for superior agility on challenging surfaces.

One of the most thrilling tasks involved configuring the rovers to independently identify and navigate toward a blue target ball, leveraging the onboard camera to capture images and train a neural network for enhanced automatic detection through machine learning. “Despite the unforeseen challenges, our teams successfully integrated locomotion and image recognition, meeting and exceeding all expectations,” stated Marti.

As the workshop came to a close, each team proudly presented their final projects, receiving feedback and recognition for their innovative work. In a remarkable bonus, the participants earned course transcripts and certificates, with the option to convert their achievements into European Credit Transfer and Accumulation System (ECTS) credits to further their academic pursuits.

This initiative not only nurtures essential skills in aspiring engineers and scientists but also supports ESA's mission to push the boundaries of space exploration. As we stand on the brink of a renewed interest in Mars with missions planned for the near future, these efforts are paving the way for future innovations in extraterrestrial robotics.
