An Intelligent Rollator for the Elderly

This work presents an intelligent rollator that can assist the elderly with limited mobility. Our proposed rollator is equipped with a tablet computer, GPU-Accelerated SoC system, LiDAR, and two hub motors. The elderly can interact with the rollator through the tablet, such as setting the traveling destination and communicating with friends. The rollator captures the frontal video streaming, segments every captured image, finds obstacles, obtains a walkable path, and thus guides the elderly to their destination. Considering that the user's walking speed is relatively slow, LiDAR also plays a vital role in estimating the user's walking speed by analyzing the user's stepping information. The functions we achieved in our rollator included guiding the elderly to the place they want to go, recording their walking status, and providing historical walking information to their caregiver. Experimental results verified the effectiveness of our proposed rollator that safely guided the elderly, particularly in the outdoor environment.
