Foot positioning has a significant impact on human body stability control when completing a manufacturing task. In classical Digital Human Models (DHM), the use of stepping strategies to generate stable postures relies on simplistic models, which generally locate the DHM center of mass (COM) at half distance between feet contact or limit the zero moment point (ZMP) projection within the base of support (BOS). Developing more comprehensive stepping models requires rigorous experimental studies to extract human movement coordination strategies during manufacturing tasks, which can be used to validate DHM models. The objective of this study is to develop an experimental test bench representing industrial conditions and to carry out experiments to provide these DHM models with parameters of postural stability. The assessed postural stability parameters in this study were the support length which is a variation of the step length, and the ZMP position with respect to the BOS. Results obtained from a pilot subject showed that the contralateral and ipsilateral legs move respectively to expand the BOS in the direction of ZMP displacement to maximize stability.
