Title: “Efficient height map learning for traversability estimation and footstep planning.”

To this day, humanoid robot locomotion most commonly follows a static walking approach that ensures stability of the robot at any time but also greatly limits the step distance. If any attempt to a more human-like dynamic walking strategy should be made, it is crucial to have a fast and reliable method for extracting necessary information about the local environment in order to be able to plan safe motions. In this talk, we present our approach that uses RGDB sensor data from a camera mounted on top of a humanoid to create a local height map at a high frequency. We analyze the map for traversability and constantly update the robot’s movements if necessary. Unlike other state-of-the-art approaches, our framework is capable of directly reacting to moving objects or sudden changes of the goal direction by recalculating footsteps in a matter of milliseconds.
