Firstly aiming at the characteristic of micromanipulation, the guidelines for selecting and designing micromanipulation mechanisms for bioengineering are proposed. In order to solve the problem of type synthesis of 3 DOF translational parallel mechanism, all the possible types of parallel mechanisms with 3 DOF are numbered, and the principles for the mechanism synthesis are also explained by applying the screw theory. In addition, based on the consideration for the advantages and disadvantages of the mechanisms as micromanipulators, some types of the mechanisms suitable for the micromanipulation for bioengineering are chosen. At last, both the CAD model and the available prototype of this mechanism are presented.
