In　this　paper,　a　robotics　system　is　designed　for　the　function　of　automatic　gripping　wires,　and　which　is　composed　of　computer　vision　system,　milli-gripper　and　control　system.　In　the　robotics　system,　thin　copper　wires　with　a　diameter　of　about　50-70　microns　are　manipulated　through　the　positioning　of　a　vision　system,　the　motion　of　multi-freedoms　control　system　and　the　gripping　function　of　milli-gripper.　A　micro　gripper　is　used　to　clamping　the　tip　of　copper　wire,　moving　to　the　pad　position　and　releasing　wires.　The　vision　system　use　a　binocular　stereo　vision　positioning　principle,　stereo　images　are　offered　by　a　stereo　light　microscope　with　two　CCD　cameras,　and　3D　position　of　copper　wire　tip　is　reconstructed　based　on　image　processing　technology.　The　gripper　is　driven　by　magnetic　force　supplied　by　a　magnetic　structure　designed　in　the　robotics　system.　And　the　gripping　action　is　executed　through　bending　deformation　of　the　cantilever　being　a　leg　of　the　gripper.　This　gripper　has　long　distance　of　run　and　high　response　frequency.
