Explanation:
Missions are very costly, and can lead the project to fail with the simplest errors. If the rover was permanently trapped on a rock or destroyed, it would have a catastrophic impact on the exploration. Thus on-board technologies would still be more traditional than what a laboratory environment has sought. The autonomous rovers will considerably increase the productivity of crew. Responsibility for their own well-being is also useful for the rovers: to prevent getting hurt, to recognize and correct recoverable hardware and software faults.
