Abstract

As nano/micro devices become smaller, it is important to manipulate them with highly accurate control. The design of micro joint is important for highly accurate movement. This paper discusses a new micro translational joint based on an elastic design concept for precise and large translational motion. By using the elastic deformation of spiral structures, translational joint can manipulate precisely and move long distance. Through finite element method (FEM) simulation, the proposed translational joint was estimated to have a precise and large translational motion. The proposed translational joint is possible to move without friction, and it can be used for micro/nano-sized manipulators. Therefore, it is expected that many applications for highly accurate devices can be manipulated with the proposed translational joint.
