The team at UHEI developed a dynamic model of the human body. Together with the team at VUA we collected the movement and ground reaction forces of a human subject performing a series of everyday activities. We later used this data to build a multi-body dynamic model of the subject that included detailed models of several muscle groups. These are necessary so that the strength of the model varies with posture and the speed of movement just as it does in real humans.
Based on the meeting between JSI, UHEI and VUA in Amsterdam in October 2016 we formulated a high-level control architecture of the spinal exoskeleton. The architecture will be implemented as a multi-layered system with reactive and model based controllers to meet the necessary ergonomic requirements for LBP prevention and treatment.
We co-organized two workshops at the 2016 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS 2016) that were held in Daejeon, Korea during October 9-14, 2016:
Based on the Requirements Workshop in Duderstadt, six core requirements of the SPEXOR technology were specified to accommodate considerations regarding the etiology of low-back pain and the biomechanics of the human spine during manual materials handling tasks.
