BACKGROUND OF THE INVENTION
[002] An automated guided vehicles (AGVs) are self-navigating load carriers or material handling devices. The automated guided vehicles (AGVs) are adaptable to travel autonomously which is eliminating need of the driver. The automatic guided vehicles (AGVs) are used in variety of applications such as transporting raw materials including metal, plastic, rubber or paper, work-in-process applications, finished goods to support production or manufacturing lines and for delivering items in areas where human reach is difficult.

[003] One of the greatest logistical problems of any adverse environment like rough terrain for distribution of items. The automated guided vehicles (AGVs) is deployed for front line troops, without any personnel, having risk navigating a combat zone. The automated guided vehicles (AGV) may travel over difficult terrain, use pre-programmed routes and be monitored at all times by a central controller.

[004] Also, one more problem effecting usage of the automated guided vehicles (AGVs) is inability of routing to safest placed once trapped or lost due to unavailability of a signal providing route details to the automated guided vehicle (AGVs).Thereby, impacting a task assigned to the automated guided vehicles (AGVs).

[005] The patent application CA2806852C titled “Sensor and method for use with an automated guided vehicle (AGV)” discloses about a sensor . The sensor installed in an automated guided vehicle (AGV) includes a plurality of sensor units electronically coupled to a sensor control unit via parallel communications. Each sensor unit may include a sensor array having a plurality of sensor elements, a conditioning circuit having one or more filter/amplifiers, and a conversion circuit. The sensor control unit may be configured to communicate with other AGV components via serial communications. The sensor is capable of obtaining and storing sensor readings with or without associated offset values and can use the sensor readings to determine the center of a magnetic field (CF) using methods that require relatively little processing power. A method of calibrating the sensor may include determining and storing offset values for a plurality of sensor elements and may be performed with the sensor installed or uninstalled to the AGV.

[006] The patent application WO2023192297A1 titled “Robotic vehicle navigation with dynamic path adjusting” discloses about a robotic vehicle. The robotic vehicle comprising at least one processor in communication with at least one computer memory device, a navigation operatively controlling a drive to navigate the mobile robot along a predetermined path, at least one sensor configured to acquire real-time sensor data, and a dynamic path adjust comprising computer program code executable by the at least one processor to cause the navigation to at least partially and/or temporarily deviate from a current path by generating a dynamically determined path or path segment based on the real-time sensor data and/or an indication in the current path to switch to dynamic path adjust. The robotic vehicle can be configured to switch path to a current and/or original path after executing a dynamically determined path adjustment. A corresponding method is also provided.
