Current situation in the development of micromanipulator driven by piezoelectric actuator;

According to the requirements of microassembly technics,a microassembly robot system with multi-manipulator cooperation is developed,which consists of two master micromanipulators with 4 DOF and one slave micromanipulator with 3 DOF.

A 3 degree of freedom integrated micromanipulator driven piezoelectric tube was introduced.

The noumenon of dual-fingered jogging-manipulator wa s designed on the basis of micro-robot of parallel mechanism with its working plate fitted with acicular fingers.

When microoperation manipulator is implementing locus programming, the designed controller can make its error estimation be converged into a small sphere of the origin, and simulation results can also verify the v.
