“…The second challenge of MBZIRC was exclusively solved by wheeled mobile robots in combination with a manipulator arm. Some teams of the MBZIRC have officially documented their results for challenge 2, for example (Carius, Wermelinger, Rajasekaran, Holtmann, & Hutter, ; Chen et al, ; Engemann, Wiesen, Kallweit, Deshpande, & Schleupen, ; Gandin, ; Shaqura & Shamma, ). Furthermore, team websites provide additional information on the robotic systems used during the competition and most teams have published progress videos.…”
