Formation Control With Obstacle Avoidance of Underwater Swarms Based on Relative Visual Feedback
Journal of Field Robotics, EarlyView.ABSTRACT Underwater multi‐robot and swarm systems require advanced methodologies for controlling collective behavior. Conventional single‐robot techniques, such as tethering, sonar imaging, and acoustic localization, are not scalable or effective for swarm applications.
