Miniature　detection　robotic　system　with　rapid　deployment　mode　is　very　suitable　for　detecting　in　disasters　due　to　its　deployment　mode.　However,　the　deployment　mode　of　the　robot　demands　excellent　anti-impact　property.　Moreover,　another　crucial　problem　resulted　from　the　small　volume　of　the　robot　is　the　difficulty　of　packing　locomotion,　sensing,　computing　and　power　subsystems　into　constrained　space.　To　solve　the　problems　above-mentioned,　a　kind　of　a　miniature　detection　robotic　system　with　rapid　deployment　mode　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　miniature　detection　robot　reliable　and　practical.
