The planet of robots

Humans have always searched for new places to explore and new ways to get where they wanted. Where no human could (yet) go, we would send robots to do a job for us. Mars, one of our closest neighbours, is currently home to quite a few robotic devices, some of which are able to move around freely, roaming the wild, red sands and relaying their experience back to the mother planet.
