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.

Pick-up truck has the advantage that can transport more baggage by the deck. However, it is inconvenient to put loads by a high ground clearance values. In this paper, we proposed a corresponding method to the high ground clearance using 4-bar linkage lift mechanism of tailgate. In addition, the validity of the lift mechanism through the prototype test is verified.
