Abstract
Example systems and methods for estimating a ground plane are provided. An example method may include determining an orientation of a body of a robotic device with respect to a gravity aligned reference frame. The method may also include determining the location of one or more contact points between the robotic device and a ground surface. The method may also include determining a ground plane estimation of the ground surface based on the determined orientation of the robotic device with respect to the gravity aligned reference frame and the determined locations of the one or more contact points. The method may also include determining a distance between the body of the robotic device and the determined ground plane estimation. The method may also include providing instructions to adjust a position and/or orientation of the robotic device based on the determined distance and the determined ground plane estimation.
