    Landing an autonomous air vehicle on a moving ground platform is an important capability for many missions but presents unique engineering challenges. This paper presents a robust autonomous landing system for unmanned aerial vehicles (UAVs) consisting of a magnetic dock and a visual servoing controller that uses a tailored set of infrared (IR) beacons. The UAV is equipped with actuated magnetic feet that allow it to “stick” to the docking pad during landing, but easily release from it during takeoff. The IR beacon array is designed so that landing can be performed in a variety of lighting and weather conditions, adding significant robustness to the system. The system is also designed to recharge the UAV battery after landing. Experimental results demonstrate that the prototype system can execute autonomous landings on a moving ground vehicle in outdoor environments at up to 4.5m/s (10 mph).

    Energetic cost of locomotion is often the gold standard measures used in autonomous robotic walking for efficiency as well as humans augmented with lower limb wearable robotics. The panel will discuss the relative benefits as well as critical disadvantages to the field’s obsession on energy cost for optimizing robotic systems and controls. Applications to clinical robotics for impaired populations, autonomous biped robotics, and wearable robotics for human augmentation will be discussed. The panel will also discuss potential alternative measures beyond energy cost to assess locomotion systems such as those associated with stability and agility.
