Publication number: 20230289494Abstract: A method for emulating an automated guided vehicle (AGV) system includes: obtaining sensor data of a virtual AGV in an emulation environment; determining a device state of a virtual device interacting with the virtual AGV in the emulation environment; sending the sensor data and the device state to the AGV system, and receiving AGV motion control information and device operation information from the AGV system. The AGV motion control information and the device operation information are generated by the AGV system based on the sensor data and the device state. The motion of the virtual AGV and the virtual device is controlled in the emulation environment based on the AGV motion control information and the device operation information, respectively. Time and effort spent by a deployment engineer on deployment and debugging are reduced, factory downtime is decreased, and an entire AGV system and an AGV sensor can be validated.Type: ApplicationFiled: July 31, 2020Publication date: September 14, 2023Inventors: Wei Feng Xu, Zachi Mann, Rahav Madvil, Jing Li
