Smart Belt: Human Motion Prediction and Fall Prevention from Wearable Sensor

Main content start

Dynamic bipedal walking is challenging to model as well as replicate on robotic platforms. Most exoskeletons use body sensors (surface EMG’s, subdermal, etc.) to predict leg motion, but the observation of the environment can reduce the need for invasive sensors and provide a longer prediction horizon. Can the observation of the surrounding traversable area be used to assist in step prediction? Can surrounding observation reduce the need for invasive sensors in prediction? Can the learned gait-surrounding relationship be used to a) assist exoskeleton motion b) provide learning by demonstration to bipedal robot c) be used by elderly and visually impaired to avoid falls?

 

Specifically for fall prevention for the elderly or visually impaired, our goal is to develop a wearable sensor that can predict a person's path and their stability over the expected path, alerting them if there is a significant possibility they may fall or become unstable.
