This paper presents a 1-DOF robot for hand rehabilitation exercises for hemiplegic patients. The robot provides the cylindrical grasp movement, which is one of the dominant Activities of Daily Living. Linkage Sliding Mechanism allows the proposed robot to be a simple and lightweight structure. Motion test for the healthy subjects are carried out to verify the performance of the robot. Consequently, it was confirmed that the proposed robot was suitable for performing hand rehabilitation treatment.

Due to the increase of income, people has a car more than one per household. So parking space is needed to minimum size for making many parking spaces. But narrow parking space causes that interference with another car is occurred when car's door is opening or closing. So sliding door is best way for solving the problem. But sliding structure of the door is difficult to apply to all vehicle because existing sliding structure is limited. For this reason, new sliding structure of the door is needed. In this study, we suggest new sliding mechanism of front door for vehicle and confirm the sliding mechanism using a finite element analysis.
