The Walking Assistant Robot assists blind people to walk independently with a Jetson Orin Nano (4GB) module. The Jetson Orin Nano executes high-level AI operations (object detection using a USB camera) and also manages low-level motor control and sensor data acquisition simultaneously. It receives obstacle and orientation data from MPU6050, VL53L1X, and ultrasonic sensors and processes it locally.

DC gear motors are controlled through motor driver modules, and Bangla voice instructions are generated using onboard text-to-speech synthesis. Powered through a Li-ion battery and buck converter, the integrated setup presents a small-sized, affordable voice-guided navigation system optimized for visually impaired individuals in resource-poor settings.
