Miniature　mobile　robots　are　very　suitable　for　initiative　reconnaissance　and　surveillance　important　targets　of　sensitive　areas.　However,　miniaturization　of　robots　will　inevitably　lead　to　lack　of　the　power　of　locomotion.　Throwable　miniature　robots　can　very　kind　to　solve　the　above-mentioned　problem.　However,　the　crucial　problem　resulted　from　the　small　volume　of　miniature　robots　is　the　difficulty　of　packing　locomotion,　sensing,　computing　and　power　subsystems　into　constrained　space.　Some　mechanical　designs　and　control　system　of　throwable　miniature　reconnaissance　robot　for　indoor　reconnaissance　tasks　were　presented　in　the　paper.　Several　experiments　showed　that　the　robot　was　useful　for　covert　surveillance　in　confined　spaces　and　can　carry　out　reconnaissance　missions　by　its　own　or　by　teleoperation.　Moreover,　experiments　also　showed　that　these　mechanical　designs　and　the　control　system　of　throwable　miniature　reconnaissance　robot　are　reliable　and　practical.　©　2011　IEEE.
