Step sequence planning for a biped robot by means of a cylindrical shape model and a high-resolution 2.5D map
چکیده انگلیسی

A novel step sequence planning (SSP) method for biped-walking robots is presented. The method adopts a free space representation custom-designed for efficient biped robot motion planning. The method rests upon the approximation of the robot shape by a set of 3D cylindrical solids. This feature allows efficient determination of feasible paths in a 2.5D map, comprising stepping over obstacles and stair climbing. A SSP algorithm based on A∗A∗-search is proposed which uses the advantages of the aforementioned environment representation. The efficiency of the proposed approach is evaluated by a series of simulations performed for eight walking scenarios.

Research highlights
► Efficient evaluation of step feasibility is achieved by a cylindrical robot model.
► Fast step sequence planning using high-resolution 2.5D occupancy grids is achieved.
► The applied numerical navigation function supports stepping over obstacles.
► Navigation function allows local planning without getting stuck in local minima.
► Stepping over obstacles and stair climbing are treated in a unified manner.
