The main part of the European Rover Challenge is an international robotics competition. University teams from around the world design, construct and program their own robots based on artificial intelligence algorithms. Thanks to ERC they build their unique competences of future engineers, scientists or software developers. The competition takes place on the world's largest artificial Martian track, reproducing the conditions prevailing on Mars (craters, rock fragments, hills, volcanoes...), which robots must cope with in numerous tasks based on actual NASA and ESA missions. Since 2020, the competition is conducted in two formulas: ON-SITE, in which teams come to Poland to participate with their own constructions, and REMOTE, in which competitors remotely control a Leo Rover robot physically moving on a Martian track located in Poland on the campus of Kielce University of Technology. European Rover Challenge is also about popularization of science and enabling international networking space. That's why, the Inspiration Zone is a crucial element of the ERC. Visitors can expect various exhibitors presenting their projects and scientific experiments, as well as meetings with special guests, industry specialists, discussion panels and workshops related to technology, robotics and space. A large part of these attractions can also be watched live during the event broadcast. Over the seven editions, the ERC has been visited by many industry authorities including Robert Cabana – current NASA Associate Administrator, Steve Jurczyk – former NASA Associate Administrator, Harrison Schmitt – NASA astronaut and member of the legendary Apollo 17 mission, and Tim Peake – European Space Agency astronaut.
