| NIMS performs an important role of monitoring the structural integrity of the reactor coolant system in a nuclear power plant. For a utility, it is difficult to manage the NIMS facility since the obsolesce part of the NIMS facility. The regulatory body also requested the upgrade of the NIMS facility for the accuracy improvement of signal analysis. Therefore, new NIMS facility based on FPGA and LabVIEW software was developed, and an operational reliability test-bed for the new NIMS facility was designed by using CompactDAQ. This paper shows the design of the test-bed and performance test of it. |

| This work presents a systematic path towards the analytical design of the optimal parameters of a two parameter second order Internal Model Control (IMC) filter for the first-order plus dead- time and the second-order plus dead-time processes. The IMC parameters are designed to minimize the control objective function comprising of weighted sum of (1) error between the process variable and set point, and (2) rate of change of the manipulated variable. The proposed IMC controller design yields the analytical expression of best/optimal value of the IMC controller parameters. |

| This study aims to determine the ideal shape of a gripper for the assembly of electric connectors for the automation of assembly processes involving electric connectors. First, the characteristics of the electrical connectors and their assembly characteristics were analyzed. Based on the analyzed characteristics, a gripper design methodology was derived using axiomatic design. Through this methodology, the shape of a double-held gripper was proposed using materials with different hardness values for the wire and connector parts. Finally, a gripper was tested. |

Design and Control of Under-Actuated Tendon-Driven Robotic Finger: Experimental Results |
|
Junyoung Park, Minji Kim, Dongjun Lee(Seoul National University, Korea) |
| We present the experimental results for design optimization and control of under-actuated tendon-driven
(UATD) robotic finger which generate the motion of human finger while maintaining the deformation in un-actuated
space small. The design of UATD robotic finger based on the recently-developed design optimization framework is firstly
presented. The actuated space motion controller which controls the system along its actuated space is then proposed.
Experiment result for the UATD robotic finger is presented with the actuation module which is bi-directional and tensioncontrolled. |

| Smart factory is one of the most important research area by replacing the human workers to robots and computers based on the robotics and artificial intelligence. Since the mobility of robots are less limited than human workers, research is required to extend the mobility of robots. This paper proposes a robot system to extend the mobility of robot by using guide-rail. Robot manipulator can be moved along to the guide-rail stability, where the direction can be changed by circular turret attached on the crossroad. We explain the conceptual design and basic prototype experiment. We expect the ro |
