Solar energy utilization for geographical exploration

There are many places in our earth which is unknown and undiscovered for human beings. But nowadays capable and adaptable robots can explore areas too dangerous or costly for humans to visit. Using this robot with Hyperspectral Image Processing we can explore the geological structure of that place, minerals containing and other geographical data. For the movement of the robot we need energy and here we are taking solar energy as our energy source. Now the problem is how to use this energy for robot navigation, task decoding, mineral searching mechanism.
