Design and Development of a Multi-Functional Robotic Walker
This project presents an autonomous walker designed for individuals with mobility limitations. It utilizes a navigation stack built on Robot Operating System (ROS) for self-directed movement guided by user-specified goals through a multimodal interface combining LiDAR, sound source localization, and computer vision. Additionally, the walker offers a mechanism for sit-to-stand mobility assistance and provides active user guidance through an array of force-sensing resistors. We successfully implemented and configured the ROS stack, fabricated a functional prototype, and conducted structural analysis. Future work focuses on fine-tuned navigation, user studies, and clinical trials to evaluate the system’s potential for real-world application, promoting independence and mobility for users.
