Smart Walker Instrumentation Using Hand Gestures for Lower Limb Impaired People

Nowadays, passive walking aids may autonomously steer or brake, needing the user to push them forward. In order to provide better support and assistance, this project develops a smart walker system with sensors and actuators. Here, hand gestures are used by the user to steer the walker. The main advantages include improved physical assistance, sensory support, cognitive support, health monitoring, and human-machine interface. Gyroscopes are used in the technique to detect the angles of hand motions and launch the smart walker in the user’s selected directions. To assess health variables including temperature, heart rate, leg position angles, and hand angles, a gyroscope, temperature sensor, and heart rate sensor are employed. Arduino serves as the control system. Senior citizens and those with lower limb problems typically use it during the rehabilitation period.
