The main contributions and innovations are as following:1 A new task decomposition model is proposed, which can decompose any maintenance task into task units, action units and motion elements. Based on virtual human`s kinematics model, an action classification criterion is provided, which is especially suited for maintenance simulation. Based on parametric modeling and encapsulation of maintenance actions, a Virtual Human's Action Database with a hierarchical architecture is designed and developed. Aiming at the reusability difficulty of captured motion data, a motion retargeting method based on path transformation is developed to reuse captured data, and several kinds of periodical ground locomotion actions are realized.2 In motion data compression, a key frame extraction algorithm based on kernel clustering method is proposed. Using Mercer kernel functions, motion data is mapped from the original space to the high-dimensional feature space, where the clustering process can be realized more efficiently. 3 A Petri Net-based locomotion-planning model is proposed to realize virtual human`s locomotion planning and walking control in dynamic environment.
