We are co-developing a multi-function robot with a Hong Kong technology firm. The patrol robot, shown in Figure 16, can be adapted to many monitoring and sensing use cases. This is the development of an indoor multi-function, Human-assisted AI and collaborative learning robot at terminals. With common autonomous platform, we can modify the functional components at different times for tasks such as patrolling, delivery, message dissemination etc. This demonstrates that IoT sensors do not have to be fixed installations, but instead can be dynamic and mobilized all around the airport and collect data for the Digital Twin model.
