Robotic Accident Prevention and Alert System for Visually Impaired

This project proposes a walking aid cane robot for the elderly and visually impaired people, which is equipped with a walking stick and force sensors in the handlebar. The cane's movement is controlled based on the force applied to the handlebar, and an ultrasonic sensor detects obstacles and alerts the user through a speaker. A driver circuit manages the cane's movement, and a MEMS sensor detects falls, stopping the cane's movement. The user's location is updated via the cloud, and a message is sent to the caregiver. The system employs various sensors, including MEMS, Heartbeat sensor, force, and ultrasonic sensors, to enhance safety. The GSM module plays a crucial role in sending alerts and notifications to the user's mobile phone in case of potential danger. The use of these sensors is intended to provide real-time information about the stick holder's status and surroundings, detecting potential dangers and alerting the user in a timely manner to reduce accidents and injuries. GPS will give the real time location danger conditions GSM will send exact location.
