Dispersing　information　detecting　robots　are　very　suitable　for　initiative　reconnaissance　and　surveillance　in　important　targets　of　sensitive　areas.　However,　the　dispersing　deployment　mode　of　the　robot　demands　excellent　anti-impact　property.　To　solve　the　problem　above-mentioned,　the　design　for　enhancing　anti-impact　capability　of　a　kind　of　dispersing　information　detecting　robot　was　presented　in　the　paper.　Moreover,　anti-impact　experiments　showed　that　the　robot　has　excellent　capability　of　anti-impact.　At　last,　the　experiments　also　showed　that　the　design　of　the　dispersing　information　detecting　robot　is　reliable　and　practical.　©　(2012)　Trans　Tech　Publications.
