Design of experiments for the evaluation of the human exoskeleton interaction in the context of small data collections

Résumé

The introduction of active human physical assistance in ThyssenKrupp's factories, specialized in the assembly of steering columns, especially on workstation where handling and packaging of steering column are necessary, is being studied to improve the working posture and to reduce the amount of torques of upper limb joints requires to perform operations. To identify the effects of such assistance systems on the biomechanical and psychological risk factors of the operators, we reproduced the workstation and the production parameters in our laboratory (production rate, the level of noise, temperature, etc.). Participants of the experiments are six real operators (N=6), females and males, that represents the three somatotypes. The range of work tasks (packing of steering columns) requires the mobilization of a large number of body segments with speed, stability and precision to perform complex movement in a closed loop sensorimotor control. Due to a small set of data, a statistical study was excluded in favor of ergonomic mapping based on observations and has required a multimodal measurement protocol that includes kinematic, force-plate, numerous physiological variables like EMG and subjective survey. These human factors allowed qualifying the range of efficiency of exoskeleton and make recommendations to the production manager and the consortium in health work.
