【Abstract】 Utilizing the method of coordinate transformation, the micro-kinematics model of a new typed 6-DOF parallel micro-moving robot was established and an analysis on its movement decoupling was advanced. By the adoption of different initial driving amount of displacement and driving mode, an analysis on the finite element model of that robot was carried out, and a further discussion was made upon its decoupling in micro-kinematics. Finally, test and verification of movement decoupling was advanced upon the developed prototype of micro-moving robot. The movement decoupling of this parallel micro-moving robot provided a theoretical foundation for its dynamic analysis, control and its simplification of demarcation.更多还原
