Robot Radius: A recording of the Laterna Magika theater performance, which represented the Czech Republic at the EXPO 2020 World Expo. Scientific and technological development has advanced considerably since Čapek's time. Radius is challenged by artificial intelligence, which has taken over the world, to advance to a higher level of existence. His transition to a new dimension will complete the elimination of humanity from planet Earth. Miřenka Čechová's production reflects the threats facing contemporary society, but like Čapek, she believes in humanity and human values.
