What is the potential problem for robotic rovers on Mars?

The limited  autonomy of the robotic rovers on Mars posed a big problem.

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.

i would say that hybridization occurs frequently in nature, because there are many types of hybrids that have occurred naturally, such as the mule (male donkey + female horse)
