The problem of injuries to nurses and other health care workers that are caused by lifting is a very serious and longstanding one. The objective of this research is to determine the fundamentals for the design and control of assistive devices that are either worn or directly operated by health care personnel for the purpose of augmenting human physical strength with the device's mechanical strength, while the wearer's intellect acts as the central control system for manipulating the device. In this research work all common maneuvers needed for lift and transfer patients will be studied first. To meet the maneuverability requirements determined in this study, several architectures for the device will be designed. Then the actuators will be designed and built to behave inherently like Hill's model of the human arm. Adaptive control rules will be developed for this assist device which prevent human-induced instability in the presence of variations in the human dynamics. The control algorithm in the device also transfers to the nurse's arms, as feedback, a scaled-down value of the patient's actual weight. The hypothesis is that these devices, when used by nurses to maneuver patients, reduce the risk of back injuries in the nurses.

护士和其他医护人员因举重而受伤的问题非常严重， 一个是长期的。 本研究的目的是确定设计的基本原理， 控制由卫生保健人员佩戴或直接操作的辅助设备， 目的是用设备的机械强度增强人的体力，而佩戴者的 智能充当操纵设备的中央控制系统。在这项研究工作中， 将首先研究抬和转移病人所需的动作。 为了满足机动性 根据本研究中确定的要求，将设计几种器械架构。 则 执行器将被设计和建造成像希尔的人类手臂模型一样固有的行为。自适应 将为这种辅助装置制定控制规则，以防止人为引起的不稳定性， 人类动力学中存在的变化。 设备中的控制算法也转移到 护士的手臂，作为反馈，病人的实际体重的按比例缩小的值。 假设这些 当护士使用这些装置来操纵病人时，可以降低护士背部受伤的风险。
