problem statement:  un manned rovers or machines are being used or deployed at serveral places
                    usually prone to human hazards.


opportunity : a scientific experiment worth tryting is that of the land rover kind of project
              on the mar's.

              embeddeding a SONAR IN TO SUCH robo's provides many a clue's to many a posssible
              scope for roving ....locomotion.

Note: The above problem statement having been encountered in various scenarios
      and detailed in various 'Proof of concepts' as mentioned in

        ....apply appropriate
      'use-case' modeling, rationalize and arrive at a workable and feasible 
       solution both commercially and techinically viable.
