This　paper　discusses　the　gripping　and　positioning　of　50-100　mu　m　diameter　wires　of　a　small　coil　in　preparation　for　soldering　while　processing　stereo　microscope　images　to　control　the　micro-gripper.　The　automated　system　for　gripping　wires　was　designed　and　implemented　to　work　with　a　stereo　light　microscope　(SLM).　The　relative　position　of　the　micro-gripper　and　the　wire　is　calculated　by　the　vision　system.　The　position　data　provides　feedback　to　a　mobile　platform　with　three　degrees　of　freedom,　so　positioning　of　the　micro-gripper　can　be　controlled.　The　performance　of　the　micro-gripper　system　has　been　evaluated　as　follows.　The　positioning　accuracy　of　feature　points　was　determined　experimentally　by　calculating　the　feature　point　coordinates　in　the　world　coordinate　frame　(WCF)　as　the　micro-gripper　moved　along　the　X　axis,　Y　axis　and　Z　axis.　The　results　were　compared　with　the　actual　motion　of　the　micro-gripper　and　the　gripping　performance　was　verified.
