Abstract
With the increasing physical proximity of human-robot interaction, ensuring that robots do not harm surrounding humans has become crucial. Therefore, we propose asymmetric velocity moderation as a low-level controller for robotic systems to enforce human-safe motions. While our method prioritizes human safety, it also maintains the robots efficiency. Our proposed method restricts the robots speed according to (1) the displacement vector between human and robot, and (2) the robots velocity vector. That is to say, both the distance and the relative direction of movement are taken into account to restrict the robots motion. Through real-robot and simulation experiments using simplified HRI scenarios and dangerous situations, we demonstrate that our method is able to maintain the robots efficiency without undermining human safety.
