  The following paper reviews recent developments in the field of optimization
of space robotics. The extent of focus of this paper is on the perception
(robotic sense of analyzing surroundings) in space robots in the exploration of
extra-terrestrial planets. Robots play a crucial role in exploring
extra-terrestrial and planetary bodies. Their advantages are far from being
counted on finger tips. With the advent of autonomous robots in the field of
robotics, the role for space exploration has further hustled up. Optimization
of such autonomous robots has turned into a necessity of the hour. Optimized
robots tend to have a superior role in space exploration. With so many
considerations to monitor, an optimized solution will nevertheless help a
planetary rover perform better under tight circumstances. Keeping in view the
above mentioned area, the paper describes recent developments in the
optimization of autonomous extra-terrestrial rovers.
