This video illustrates our work on contact points planning and its recent enhancement by two new functionalities. First, by taking advantage of the possibilities offered by our initial posture generator, we include additional tasks in the planning that are not related to locomotion. Second, we refine the potential function that guides the planner so as to cope with more challenging scenarios. We then...
We present a motion planning algorithm that computes rough trajectories used by a contact-points planner as a guide to grow its search graph. We adapt collision-free motion planning algorithms to plan a path within the guide space, a submanifold of the configuration space included in the free space in which the configurations are subject to static stability constraint. We first discuss the definition...
This paper proposes a real-time implementation of collision and self-collision avoidance for robots. On the basis of a new proximity distance computation method which ensures having continuous gradient, a new controller in the velocity domain is proposed. The gradient continuity encompasses no jump in the generated command. Included in a stack of tasks architecture, this controller has been implemented...
This paper deals with the problem of object reconstruction for visual search by a humanoid robot. Three problems necessary to achieve the behavior autonomously are considered: full-body motion generation according to a camera pose, general object representation for visual recognition and pose estimation, and far-away visual detection of an object. First we deal with the problem of generating full...
This paper presents a new method for strictly convex hulls (i.e. bounding volume) generation made by assembling patches of spheres and toruses (STP-BV). This bounding volume allows to compute proximity distances with the guarantee of their gradients' continuity. This bounding volume is computed off-line; it slightly over-covers the polyhedral convex hull of the geometrical form. Given a pair of convex...
