Throwable　miniature　robots　are　very　suitable　for　initiative　reconnaissance　and　surveillance　in　important　targets　of　sensitive　areas.　However,　the　throwing　deployment　mode　of　miniature　mobile　robots　demands　excellent　anti-impact　property.　Moreover,　another　crucial　problem　resulted　from　the　small　volume　of　miniature　robots　is　the　difficulty　of　packing　locomotion,　sensing,　computing　and　power　subsystems　into　constrained　space.　To　solve　the　problems　above-mentioned,　the　design　and　realization　for　a　kind　of　throwable　semi-autonomous　reconnaissance　robot　was　presented　in　the　paper.　Moreover,　Finite　element　simulation　analysis　and　anti-impact　experiments　showed　that　the　robot　has　excellent　capability　of　anti-impact.　At　last,　the　experiments　also　showed　that　the　design　of　the　throwable　semi-autonomous　reconnaissance　robot　is　reliable　and　practical.　©　2011　IEEE.
