SKA Robotics is a part of the Students Space Association based at the Faculty of Power and Aeronautical Engineering of Warsaw University of Technology. Our association has a long-lasting experience, reaching URC 2009 with rover Scarab, three generations of rover ARES, which participated in competitions from 2014 to 2016 and Rover Sirius, which participated In ERC 2018, 2019, 2021 and URC 2019. The second rover of the Sirius program is Sirius II, whose design process began during the COVID-19 pandemic. The rover and our team competed in ARC 2022, ERC 2022, 2023 and URC 2023 finals. Our main motivation for taking part in the competitions, apart from enjoying the competition, is to develop our skills in order to more easily get a job in, among other things, the space industry.
