To enable robust dynamic walking on the Atlas robot, we extend our previous work by adding a receding-horizon component. The new controller consists of three hierarchies: a center of mass (CoM) trajectory planner that follows a sequence of desired foot steps, a receding-horizon controller that optimizes the next foot placement to minimize future CoM tracking errors, and an inverse dynamics based full...
We present a motion planning and control method for contact-rich full-body behaviors, particularly, the car egress task of the DARPA Robotics Challenge (DRC). We take advantage of human experience by manually specifying multiple task phases, each of which has a specific contact mode. Then, we optimize a sequence of static robot poses as well as contact locations that satisfy all constraints, such...
We present an optimization based real-time walking controller for a full size humanoid robot. The controller consists of two levels of optimization, a high level trajectory optimizer that reasons about center of mass and swing foot trajectories, and a low level controller that tracks those trajectories by solving a floating base full body inverse dynamics problem using Quadratic Programming. Our controller...
