The need for synthetic automation is increasing in preparation for a gradual decrease in laboratory research manpower due to low birth rate and aging. In this study, the existing laboratory synthesis method is analyzed based on the systems engineering technique. Then, it led to the derivation of the system requirements for a fixed-based robot manipulator capable of recognition, decision and control. The robot is equipped with replaceable modular end-effectors and designed depending on the purpose and process of the synthesis. The robot with an end-effector was implemented as PoC(Proof-of-Concept), and the functions for pipetting automation was verified.

In this paper, a robotic system which consists of a precision manipulator and a micro gripper for a micro system assembly is presented. By the experiment, we proved that the developed the system gives acceptable performance when minute operations. Developed the micro-nano robot is actuated by newly proposed modular revolute and prismatic actuators. As an end-effector of this system, micro gripper is designed and fabricated with MEMS technology and the displacement of jaw is up to 142.8 micro meter. We think that new robot system will be appropriate for micro system assembly tasks and life science application.

This paper presents kinematic calibration of parallel manipulators with partial pose measurements using a device that measures a rotation of the end-effector along with its position. The device contains an LVDT, a biaxial inclinometer, and a rotary sensor and facilitates automation of the measurement procedure. The device is designed in a modular fashion and links of different lengths can be used. The additional kinematic parameters required for the measurement device are discussed, kinematic relations are derived, and cost function is established to perform calibration with the proposed device. The study is performed for a six degree-of-freedom(DOF) fully parallel HexaSlide Mechanism(HSM). Experimental results show significant improvement in the accuracy of the HSM.
