Rover simulation and tools RCET RPET and RCAST developed in Europe Mars rover chassis evaluation tools RCET have been developed in Europe to support the design of planetary rovers Michaud et al. 2006 . RCET which was developed jointly by Contraves Space Ecole Polytechnique Fédérale de Lausanne the German Aerospace Center DLR and others accurately predicts the rover performances of the locomotion subsystem. It consists of a two-dimensional 2D rover simulator that uses a tractive prediction module to compute the wheel ground interaction. 3D simulation can also be performed with the help of .
