A torque-controlled back-support exoskeleton to assist manual handling is presented. Its objective is to provide a significant portion of the forces necessary to carry out the physical task, thereby reducing the compressive loads on the lumbar spine and the associated risk of injury. The design rationale for a parallel-elastic actuator (PEA) is proposed to match the asymmetrical torque requirements...
This paper presents a novel sensor fusion methodology to dynamically detect weight variations and the position of an exoskeleton system. The proposed methodology is intended for tasks of lifting and lowering heavy weights with an industrial exoskeleton to substantially reduce spinal loads during these activities.
Manual material handling is one of the most frequent operations in industrial manufacturing processes. To avoid undesirable spinal loads, workers are often required to use external aid devices. This paper presents the analysis and design concept of a wearable assistive device for reducing the spinal loads during lifting tasks. A simplified model is used to compare the effects of two possible configurations...
