Resumen

The development of the intelligent system "Tawna Yachaq"is presented for the safe movement of a volunteer with visual disabilities. This system includes a cane with an obstacle detection system, an artificial vision system for the identification of objects and people, with an alert and position warning system in a controlled environment. The mechanical system consists of an intelligent system protection box developed in Fusion 360 software. The electronic-electrical design of the intelligent system, based on the Raspberry Pi 4B microprocessor. Includes a Neo 6M GPS module to provide real-time user location. Using HC-SR04 ultrasonic sensors and a buzzer module, it emits an alert sound to the user. In addition, an ESP32-Cam camera that uses computer vision algorithms detects predefined objects in the university campus environment. The system is powered by 7.4V Lion rechargeable batteries, with an LM2596 voltage regulator ensuring stable operation. A patent is proposed as future work.
