Pudu Robotics demonstrates the PUDU D5 quadruped robot mapping large sites and conducting autonomous patrols in complex environments. The system can create maps covering areas at the million-square-meter scale, navigate routes and execute assigned tasks at designated points. During operation, D5 monitors mission status and automatically returns to its charging station when power is low or a patrol is complete. The demonstration shows how autonomous navigation, mobile inspection and self-charging can support efficient industrial and power-facility patrols with less routine operator involvement.
