| Research Abstract |
A balance controller for humanoid robots based on the Reaction Null Space method was developed. The controller ensures reaction/balance recovery control to external impacts and to continuous forces on various body parts while standing upright. First, the ankle and hip strategy in the sagittal plane have been integrated such that smooth transition between these strategies is realized, depending on the magnitude of the continuous external force. Second, we used motion capture data to analyze human responses to external forces in the frontal plane. We have identified four reaction patterns, not all of them yet reported in the biomechanics literature : frontal-plane ankle strategy, lift leg strategy, cross-leg step strategy and side step strategy. The frontal-plane ankle strategy and the lift leg strategy have been integrated with a smooth transition between them and applied successfully to a small humanoid robot HOAP-2.Third, we have applied the controller to ensure reaction/balance recovery with external forces with offset from the sagittal and frontal planes(out-of-plane patterns). This reaction pattern has been confirmed via simulations.
