Ultrasonic range sensors are one of the core technologies enabling robots to operate autonomously. By emitting high-frequency sound waves and receiving the reflected echoes, these sensors use the Time-of-Flight (TOF) principle to calculate the distance to obstacles in real time. When an obstacle is detected within a preset safety range, the robot’s main control system immediately triggers obstacle-avoidance actions—such as decelerating, turning, or replanning the path—to automatically navigate around the obstacle. The AU0016 is a sensor designed specifically for commercial robots. Integrated into autonomous navigation and obstacle-avoidance systems, it ensures the robot’s safe operation in complex environments. The product employs dual-probe separation technology to effectively reduce interference, provide high-precision distance measurement data, and ensure accurate positioning.
