This study aims at designing sleeves which are suitable for arm shapes and arm movements. With the samples of of ordinary 24 women aged from 20 to 22, the arm shapes and movements were measured 3-dimensionally using a motion analyzer and a sonic digitizer, and then clasified into three characteristic types (A, B, and C). Our analysis leads to the following conclusion. The factors classifying arm shapes are the length from acromion to posterior armpit point, arm hole length, the cap height, difference in height between anterior and posterior armpit points, armhole circumference, upper arm circumferemce, armhole depth, and underarm circumference. The characteristics of arm type A is that the armhole depth and the length from acromion to posterior armpit point are the largest, while the circumference inbe- tween upper arm and elbow is the smallest among the three arm types. Thus, the large circumference difference between upper and lower arms is the most notable in arm type A. The factors classifying arm shapes for arm type B are the smallest except for the circumference inbetween upper arm and elbow which is larger than that for arm type A. The circumference difference betweemn upper and lower arms is small for arm type B. Arm type C has the smallest armhole depth, while other factors are similar to those for arm type B. In type C, the size of upper arm is comparatively small on the frontal plane, while it is the largest on the sagital plane.

로봇의 ARM에 대한 연구는 로봇공학의 매우 중요한 부분이고 이에 대하여 오랜 기간 동안 많은 연구 개발들이 꾸준히 진행되고 있으며, 인간과 로봇의 동작에 있어서 움직임의 차이를 줄이기 위하여 다양한 연구 방법론들이 제시되고 있다. 특히 인간의 동작에 근접하는 로봇의 동작을 구현하기 위해서 로봇의 중요한 구성 요소 중의 하나인 ARM을 더욱더 중점으로 연구를 진행하고 있고, ARM을 로봇뿐만 아니라 다양한 분야에서 활용하기 위해 많은 노력을 하고 있다. 본 논문에서는 인간의 팔 동작에 근접하는 로봇 ARM 동작을 구현하는 Smooth ARM Motion 알고리즘을 설계하기 위하여 로봇의 기존 ARM 동작을 파악하고 그 특성을 분석하였다. Smooth ARM Motion은 중대형 로봇 설계에서 이미 적용되어 있지만 소형의 모터 서보를 사용하는 로봇에서는 적용되기 어려운 문제점을 가지고 있다 따라서 본 논문에서는 소형 모터 서보 시스템에서 Smooth ARM Motion을 구현하기 위하여 효과적으로 ARM을 제어하는 방법론을 도출하는 데에 필요한 제어 변수들을 제시하고, Arduino 환경에서 Smooth ARM Motion설계하기 위한 ARM에 대한 제어 변수들 간의 상관관계들을 실험을 통하여 분석하였다.

In this paper, an unilateral teleoperation system using an universal master arm is developed. This system is composed of an universal master arm, a slave arm and a telerobot controller. The universal master arm has a vertically articulated type link structure, while an industrial robot is used as a slave arm. As the shapes of master arm and slave arm are different, the workspace mapping is needed, which maps the workspace of master arm to that of slave arm. Experimental results show that the slave arm of the developed system effectively follows the operator's motion.

This study proposes the design method for the robot rotation arm which the end effector that is connected in end of the arm keeps parallel motion even though the robot arm rotates. So far, most robot arm rotates together the end effector when the arm rotates. For this, this study proposes the mechanism that the arm is linked to each 4 parallel link so that rotation is possible by 4 pins, and the rotation arm connects 2 joints of diagonal line direction to a link in each 4 joint for rotation, and designs so that can change length of the link. For verification of design, this study targeted that develop the rotation arm for medical examination that use in ophthalmology. It is important that a medical robot offers comport to patient and design compactly so that medical examination and treatment space may can be defined enough. It is designed so that all drive elements may be positioned on interior of the arm and optimization of design for main parts was carried out in this study for this. The robot arm which is developed in this study manufactured to use by medical phoropter arm, and got good result by an experiment. The robot rotation arm which is proposed in this study is judged to contribute very effectively in case use of a medical robot arm for medical examination and treatment, also the robot arm which the end effector that is connected in the end of the arm needs to keep parallel motion. And, the robot arm which is developed in this study made an application as license.

The purpose of this study was to investigate the most appropriate arm-hole depth in 9 positions of arm movements. This subjects were four females, college students aged 18 to 23 years old. The clothing size 55 was used for this study. In the experiments for the investigation of the arm-hole depth, the evaluations were performed for aesthetic view, clothing adaptability to arm movements, and quantity of materials pulled up by 9 movements of arm. The results of this study were as follows: 1) In the aesthetic evaluation, there were no significant differences in arm-hole depths. 2) In the evaluation of clothing adaptability to arm movements, the experiment clothes, in which-arm-hole depths were raised, had more positive evaluations especially with the increasing the angle of arm movements. 3) In the evaluation of clothing adaptability to each body areas, there were no significant differences in all body areas except upper arm circumference blade. 4) In the evaluation of quantity of materials pulled up by arm movements, the clothes of B/4-2 arm-hole depth had the least amount pulled up by arm movements, which showed the highest adaptability to arm movement.

In our previous work using a motion analyzer and 3-dimensional sonic digitizer, the arm shapes for 23 women in their early twenties were classified into three characteristic types. In order to design sleeves, suitable for arm movements for the three characteristic arm shapes, a relationship between arm length variation and shoulder/elbow angles has been investigated for four cases of arm movements (flexion, extension, adduction and abduction). Each arm movement can be characterized by the changes in shoulder angle and the changes in elbow angle at the maximal shoulder angle. In all the four cases of arm movements, the changes of shoulder length and cap height are largest at the maximal shoulder angle. These changes were little affected by changes in elbow angle. The changes in the lower arm length and the difference between cap height and upper arm length are the largest at the maximal elbow angle of the maximal shoulder angle. There is a linear relationship between cap height and shoulder angle during arm movements; thus, in designing sleeves the cap height can be determined from the regression of cap height vs. shoulder angle.

In this research, a novel mater arm was studied as a teaching device for an underwater revolute robot arm used as a slave arm. The master arm was designed to be a seven-degree-of-freedom (DOF) structure, with a structure similar to that of the slave arm, and to be desktop size to allow it to be worn on a human arm. The master arm with encoders on the joints was used as an input device for teaching a slave robot arm. In addition, small electric magnets were installed at the joints of the master arm to generate the haptic force. A control system was designed to sense excessive force and torque in the joints of the master arm and protect it by controlling the position and velocity of the slave arm through the encoder signal of the master arm.
