This article investigates an adaptive dynamic event triggering enclosing control for multirobot systems with angle constraints. A dynamic event triggering controller excluding Zeno behavior is designed by combining dynamic auxiliary variables. Based on bearing measurements, angle constraint is used to avoid the collision from the robot to the target and ensure that robots do not collide with each other. With the help of Lyapunov stability theory, the developed control method can ensure the boundedness of all signals within the closed-loop system, and angular errors converge to a small neighborhood around the origin.
