JOURNAL FREE ACCESSThis paper considers the human grasping ability experimentally. The motivation for this work is to enable a robot hand to grasp an object of unknown weight. We begin with an examination of human behavior of shaking an object up and down using thumb and middle finger. Experimental results show that the human varies a grasp force to compensate for the inertial force of the object, and use his slip sense to generate a grasping force just greater than the minimum required for grasping the object. Next, to examine how humans determine grasp forces in the presence of slip on the fingertips, we conduct the experiment, in which a human touches the object which is put on a table and grasps the object using the information only from the cutaneous sensors when acceleration is applied to the object by moving the table down. Two methods that can predict when and how fingers will slip upon a grasped object are considered. Experimental results show that when slip is detected by sensing skin acceleration, the grasp force becomes much greater than the minimum force required for grasping by adding the force which is proportional to the acceleration.View full abstractDownload PDF (823K) -

JOURNAL FREE ACCESSThis paper presents a pilot's control characteristics of an STOL aircraft operated in approach and landing using the fixed base simulator. Control method of the STOL aircraft at the speed instability condition (the backside of the speed-drag curve) in landing from 50 (m) hight are discussed. As steady state value of flight path response at the backside area has opposite sign to it at the frontside area, it is very difficult to control the STOL aircraft at such a condition for a pilot. And then, manual reverse control of a pilot is considered as one of a control method which satisfied landing of the STOL aircraft at the backside area. The results show that comparing the experimental results with the simulation, such reverse control with the quasi-linear and the bang-bang control is available method to control the STOL aircraft at the backside area.View full abstractDownload PDF (856K) -
A study on the Team Activity Evaluation Method (TAEM)Kunihide SASOU, Akihiko NAGASAKA, Takeo YUKIMACHI1993 Volume 29 Issue 2 Pages 111-120

JOURNAL FREE ACCESSThis study focused on the importance of what the operating team successfully and adequately diagnosed and behaved during a plant abnormal condition. This paper developed a method for trial to evaluate the team faculties, referring to the findings from simulated experiment studies, studies on group psychology or group dynamics. This method divided the team faculties into three functions, “Direction and Orientation”, “Recovery” and “Maintenance of cooperation” to evaluate the team activity under simulated abnormal conditions. This paper also noted some applications of this method to the results of some simulated experiments. As a result, it was found that this method made clear the differences of the faculties depending on the situations or the teams. This also made clear some factors hindering the three functions from working, some characteristics of each team or some important factors to enhance the team faculties.View full abstractDownload PDF (2939K)
