This research develops a collaborative system for fall detection and response by integrating Wi-Fi sensing with an autonomous mobile companion robot. The system accurately detects falls in non-line-of-sight (NLOS) scenarios and enables the robot to navigate complex indoor environments, including door traversal, to provide timely assistance.

Key insights

  • Transfer learning significantly improves the accuracy and convergence of Wi-Fi CSI-based models for specific fall detection tasks in complex NLOS environments.
  • The combination of non-intrusive Wi-Fi sensing and autonomous mobile robotics creates a holistic, privacy-preserving solution for emergency response in elderly care.
  • Mobile manipulators can robustly navigate and perform complex interaction tasks, such as unlocking and opening doors, to provide timely assistance in real-world indoor settings.
