Design of a two-dof planar micro-robot

A two-dof planar micro-robot is designed,which can perform high precision microoperation.Flexure hinge is used as revolute pair to meet the demand of high precision,non-clearance,non-friction and fast response.The system is driven by two V-style thermal micro-actuators.Coupling analysis of the micro-robot is carried on in ANSYS,and the result demonstrates that the output displacement has a linear relation to the voltage difference.Therefore the design and synthesis of the micro-robot’s track can be easily performed.
