Abstract: A method for activating a wake-up module of an autonomous guided vehicle (AGV) when the AGV is operating in a standby state, determining whether a global wake-up command was broadcasted by a fleet management system, and activating an on-state associated with the AGV in response to determining that the global wake-up command was broadcasted by the fleet management system.

Abstract: An automated guided vehicle (AGV) fleet system having a facility supervisory system and a plurality of AGVs. Each AGV has a power control module that includes: a wakeup circuit having at least one command input and at least one control output and being operable by electrical power received from a power source. The wakeup circuit includes a timer circuit and one or more parameters that can be configured via the command input, the timer circuit being coupled to the control output to change the output state of the control output in dependence on the parameter(s).

Abstract: A drive mechanism for an AGV that includes a drive unit for propelling the AGV and a steering unit for steering the AGV. The drive unit has a drive motor, drive transmission, and a drive wheel. The steering unit has a steering motor. Both motors are fixedly mounted on the AGV and remain stationary relative to each other while the drive motor rotates the drive wheel and the steering motor steers the drive wheel. The drive transmission couples the drive motor to the drive wheel and can be at least partially mounted within a gear housing that is rotatably mounted via a bearing so that the drive motor can be operated to move the AGV via power transferred to the drive wheel via the drive transmission, and the steering motor can be operated to steer the drive wheel by rotation of the gear housing and drive wheel via the bearing.

Abstract: A sensor system for use with an automated guided vehicle (AGV) includes a plurality of sensor units electronically coupled to a sensor control module 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 module may be configured to communicate with other AGV components via serial communications. The sensor system 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 using methods that require relatively little processing power. A method of calibrating the sensor system may include determining and storing offset values for a plurality of sensor elements and may be performed with the sensor system installed or uninstalled to the AGV.
