    Do you know how to check if the obstables are around me within a ,say, given radius ? Any research papers available out there for me to read? Thanks

    Please elaborate. Presumably one could use the technology that auto-focus cameras use, or something like a laser (or optical) range finder:

    or radar (i.e. microwave) systems - http://www.offshore-technology.com/contractors/instrumentation/miros/,

    or acoustical systems - http://www.robot-electronics.co.uk/htm/srf1.shtml.

    The technology depends on the range.
