Intelligent Feedback System for Assistive Walking Technology is a device that provides real-time feedback to patients with lower limb disabilities to improve their walking time and overall walking pattern. By using a combination of sensors and a Neurosensory Buzz, our device provides users with sensory feedback that helps them better understand their gait and improve their walking. It can be used in conjunction with the open-source Exosuit project to provide better rehabilitation for people. Our project is open-source, meaning it can be easily replicated and adapted by others. With our device, we hope to make a positive impact on the lives of people with lower limb disabilities worldwide.

    Overview

    We provide detailed and step-by-step instructions on how to connect and program these components to build the device. We also include clear images, diagrams, and code snippets to help readers follow along.

    The motors will be connected to the patient's body and will make the user move. The sensory feedback will be provided by the gyroscope and accelerometer connected to the patient's body. There will be an array of force effective sensors connected to the patient's foot. The sensor array gives feedback to the Neurosensory Buzz so that the user will get a sense of each step and will improve the walking time and overall walking pattern.

    The device is used along with the open-source Exosuit project to provide better rehabilitation for people.
