Our team operates as part of the Students’ Robotics Association (Koło Naukowe Robotyków KNR) at the Faculty of Power and Aeronautical Engineering of Warsaw University of Technology. The Association is one the biggest at the University and consists of robotics enthusiasts, who design and build highly advanced robots. Our first rover was developed three years ago. It was based on Crawler – a 1:2 scale prototype construction. The rover debuted at the University Rover Challenge 2018 in Utah state. Upon this time we have constructed three new versions of the rover and participated in the ERC four times (2018, 2019, remote 2020, on-site 2021), thus we have learnt a lot about participating in such international competitions (both remote and on site).
