AGV Ultrasonic Obstacle Avoidance Guide: Choosing 40kHz / 48kHz / 55.5kHz, Blind Zone, Beam Angle & Crosstalk

1. Introduction: Why Frequency + Blind Zone + Crosstalk Decide AGV Obstacle-Avoidance Reliability For AGVs, “seeing an obstacle” isn’t enough—what matters is whether the system can detect it early and consistently, especially in the near field where the safety margin…
