Multi-Joint Active Collision Avoidance for Robot Based on Depth Visual Perception

<正>Dear editor,Human-robot collaboration is a research topic that has numerous potential applications, such as in smart cities. An important safety consideration in human-robot collaboration is collision avoidance[1]. Many studies have prioritized collision avoidance of the robot end-effector. However, multi-joint(whole-body) collision avoidance is also very important in complex working scenarios. Several studies have achieved multi-joint collision avoidance by estimating the distance between obstacles and control points placed on the robot body,
