Students Explore Mars Robotics in ESA Academy Workshop
In a groundbreaking initiative, university students recently participated in an engaging hands-on training course offered by the ESA Academy at ESA’s ESTEC technical center in the Netherlands. This unique workshop provided a platform for 30 budding engineers and robotics enthusiasts from 14 different ESA Member States and Canada to dive deep into the realm of Mars exploration through the use of 3D-printed rovers.
The students were equipped with ExoMy rovers, innovative 3D-printed vehicles inspired by ESA’s upcoming Rosalind Franklin rover, which is set to explore the Martian surface in the near future. Each ExoMy rover featured six wheels, a camera, and a Raspberry Pi computer, allowing students to engage with open-source hardware and software complemented by detailed assembly guides. This hands-on experience not only fostered technical skills but also encouraged collaboration and creativity among the participants.
Marti Vilella Ramisa, an ESA robotics engineer, emphasized the workshop’s goal: “The goal was to introduce them to designing and operating a 3D-printed rover, inspired by the Rosalind Franklin ExoMars rover set for deployment later this decade.” Over the course of four intensive days, students attended lectures and practical sessions that enhanced their understanding of robotics and autonomous systems.
The workshop began with foundational sessions on robotics, coupled with an introduction to the ExoMy rover’s capabilities. Students were challenged to program their rovers to detect and navigate towards a blue ball within a simulated Martian environment. Initial exercises included hands-on simulations and manual control tests on terrain designed to mimic the characteristics of Mars, using a wireless gamepad for operation.
Throughout the training, participants delved into various locomotion modes for their rovers, developing algorithms to improve maneuverability. They implemented two new locomotion modes to ensure greater adaptability in the variable terrain. The teams leveraged the rovers’ built-in cameras to capture and tag images of the target ball, employing machine learning techniques to train a neural network for automatic detection.
“The culminating task was to integrate locomotion and image recognition to autonomously locate and approach the ball, despite its unknown position,” explained Vilella Ramisa. This multifaceted challenge tested the students’ programming skills, creativity, and problem-solving abilities while fostering a spirit of innovation. Remarkably, all teams managed to meet the challenge and exceeded expectations, showcasing the potential of collaborative efforts in advancing technology for space exploration.
Upon completion of the workshop, students presented their projects, receiving evaluations that acknowledged their hard work and achievements. Additionally, they were awarded course transcripts and certificates, which can be converted into ECTS credits at their home institutions. This recognition not only enhances their academic profiles but also paves the way for future endeavors in engineering and robotics.
As ESA continues to develop training programs that bridge education and real-world applications, the impact of such initiatives is poised to extend beyond the classroom. The exploration of Mars is a complex endeavor that requires innovative solutions and a new generation of skilled individuals ready to tackle the challenges of space travel.
