1. A method for verifying one or more fields of one or more sensors on an automatic guided vehicle (AGV), the method comprising:
- driving, by a control module, from a starting location towards a first test object at a first speed;
detecting, by a sensor module communicatively coupled to the one or more sensors, the first test object in the one or more fields;
recording, by a processor module, a detection location indicative of a location of the AGV at which the sensor module detected the first test object;
calculating a distance from the AGV to the first test object by comparing the detection location to a location of the first test object;
comparing the calculated distance to a configuration distance stored in a memory module; and
outputting, by the processor module, a data message indicating whether the one or more fields of the one or more sensors on the AGV have been verified,wherein the one or more fields comprise a warning field and a protective field, andwherein, responsive to an object being detected in the warning field by the sensor module, the control module causes the AGV to slow down and, responsive to an object being detected in the protective field by the sensor module, the control module causes the AGV to come to a stop.

Abstract
A method and system for auto safety verification of automatic guided vehicle (AGV) sensors is presented. An auto safety verification test can be performed autonomously by the AGV to ensure that sensors on the AGV are configured correctly and working properly. The auto safety verification test avoids human errors that exist in manual verification tests and significantly reduces the amount of time required to verify sensors on the AGV.
