Because of deterioration of strength, range of joint motion, and balance ability, most care-dependent older adults require assistance to move from a seated position to a standing position. Although many sit-to-stand assisting apparatuses consisting of a seat, power transmission mechanism, and sensors have been developed, most of movements depend several actuators as the power transmission mechanism. This study aims to develop the chair-typed apparatus of nine-link mechanism with 1 degree of freedom at first, then to prove the possibility that the apparatus can be operated through the recognition of human behavior by one sensor. Here, the nine-link mechanism is divided into two mechanisms: the five link for raising the height; the four link for rotating. The mechanical part enables two input links for two mechanisms to be driven by one linear actuator simultaneously. The measurement with the infrared sensor enables the assistive apparatus to be operated automatically while patterns from measured data help the apparatus recognize what the user want to do: one is the sit-to-stand movement; the other is the stand-to-sit movement. It is discussed that the operating method through the human behavior is helpful for most older adults who are not familiar with the operation of machine.

通过识别人类行为来操作辅助设备:具有1个自由度的九连杆机构的椅子型辅助设备的开发和实验评估

由于强度,关节运动范围和平衡能力的下降,大多数依赖护理的老年人需要帮助才能从坐姿转变为站立姿势。尽管已经开发了许多由座椅,动力传递机构和传感器组成的坐姿辅助装置,但是大多数运动依赖于多个致动器作为动力传递机构。这项研究的目的是首先开发一种具有1个自由度的九连杆机构的椅子型设备,然后证明该设备可以通过一个传感器识别人类行为来操作该设备的可能性。在此,九连杆机构分为两个机构:用于提高高度的五个连杆;和用于提高高度的五个连杆。旋转的四个环节。机械部分使两个机构的两个输入链接可以由一个线性致动器同时驱动。红外传感器进行的测量使辅助设备能够自动操作,而来自测量数据的图形则可以帮助该设备识别用户想要做的事情。另一种是站立运动。讨论了通过人的行为进行操作的方法对大多数不熟悉机器操作的老年人很有帮助。
