초기 직경이 500$\mu\textrm{m}$인 텅스텐 봉을 전해에칭을 통하여 끝단 직경이 수 $\mu\textrm{m}$인 텅스텐 팁으로 가공하였다. 그리고, 적절한 전처리 과정을 거친 다증벽 탄소나노튜브를 제작된 텅스텐 팁 끝에 적절한 매니퓰레이션을 통하여 부착하였다. 이렇게 제작된 나노 팁(텅스텐 팁과 탄소나노튜브로 구성)은 매우 긴 탄소나노튜브의 길이 때문에 나노 팁으로 사용하기에 부적절한 경우가 많다. 즉, 나노 그리퍼로서 사용하기에는 적합하지 않은 경우가 있다. 이러한 점을 극복하기 위하여 전해에칭을 이용하여 나노 팁의 길이를 나노 그리퍼로 사용하기에 적합하도록 조절하였다.(중략)

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.

Flexible tactile sensors, which are primarily used as grippers in robots, are mainly used to handle highly elastic or highly flexible objects. That is, flexible grippers are used when an object cannot be sufficiently controlled by applying a specific output force or taking a specific grabbing action. This is because a flexible tactile sensor needs to measure the pressure applied directly to held objects while deforming according to the shape of the object to be handled. CNT-based sensors used to be made from a highly flexible polymer to give flexibility and it is known that the sensors are greatly affected by the contact resistance of the terminal that connects the sensor to an electrical circuit; therefore, this paper clarifies the contact resistance of MWCNTs-based flexible tactile sensors and terminals. The effects of main and plating materials for terminals are investigated and the combinations of main and plating materials that exhibit contact resistance are measured in a typical industrial environment.
