Publication number: 20240103528Abstract: Implementations are described herein for inspecting industrial facilities using remote sensor packages and wireless access points (WAPs) carried by mobile robots. In various implementations, aspect(s) of an industrial process facility may be monitored using sensor package(s). The sensor package(s) may generate one or more sensor signals, and based on the one or more sensor signals, detect anomal(ies) of the monitored aspect(s) of the industrial facility. Responsive to detecting anomal(ies), the sensor package(s) may modulate a long-range low-bandwidth (LR-LB) signal to indicate detection of the anomal(ies) in the monitored aspect(s) of the industrial process facility. Another component of the industrial facility may identify LR-LB signal(s) representing detection of anomal(ies) by sensor package(s) and instruct mobile robot(s) to travel to area(s) of the industrial facility to receive sensor data carried by a short-range high-bandwidth (SR-HB) signal emanating from that area.Type: ApplicationFiled: September 22, 2022Publication date: March 28, 2024Inventor: Naoyuki Fujimoto
