title = "COUPLED ORBIT-ATTITUDE MOTION OF ASTEROID HOPPING ROVER BY CONSIDERING ROUGH TERRAINS",
abstract = "This paper presents a numerical methodology to investigate the coupled orbit-attitude motion of a rover under the unilateral constraint of asteroid terrains. A newly rocky polyhedral model is generated by considering the complex surface terrains with rocks and boulders. The coupled attitude-orbit dynamics are discussed in terms of 6 DOF orbital, surface, and collision motion. The interaction between the rover and the rocky polyhedral model is performed by directly integrating the dynamical equations. To evaluate the effectiveness of the method, a hypothetical deployment case on the asteroid 101955 Bennu is carried out with its application to a spheroid rover. The influence of terrains is investigated by comparing the trajectories involving the original polyhedral model with the rocky model.",
