Gripper　is　one　of　the　most　important　parts　of　robot　because　of　contacting　with　workpieces　directly　and　has　attracted　lots　of　research　interests.　However,　the　existing　grippers　are　either　simple　in　function　or　complex　in　structure.　In　this　paper,　we　will　propose　a　one-DOF　gripper　based　on　a　compliant　mechanism　with　four　identical　twofold-symmetric　Bricard　linkages.　A　mobile　network　with　four　identical　twofold-symmetric　Bricard　linkages　with　particular　design　parameters　is　constructed　at　first.　Kinematics,　such　as　mobility,　singularity,　and　folding　performance,　is　then　analyzed　to　show　the　potential　of　realizing　the　function　of　grasping.　The　result　is　demonstrated　with　a　physical　prototype.　To　simplify　the　fabricating　process,　a　compliant　mechanism　of　the　network　is　designed　and　fabricated　with　a　single　polypropylene　board,　and　the　grasping　function　is　realized　by　a　cable-driven　scheme.　Some　grasping　experiments　are　carried　out　on　different　types　of　objects　which　shows　that　the　proposed　and　fabricated　four-figure　gripper　is　simple　in　structure　and　has　a　great　grasping　function.　The　work　provides　a　new　idea　for　the　design　of　grippers　with　low　cost,　simple　structure,　and　rich　functions.　©　The　Author(s),　2022.　Published　by　Cambridge　University　Press.
