About Snow Plowing Rover
Sept 2023 - Dec 2023
This autonomous robotic snowplow is designed to efficiently clear snow in predefined areas, utilizing advanced sensor
technology and intelligent software systems. Built as part of an innovative engineering project, this rover combines a
plow mechanism with an array of sensors, including ultrasonic and line-following sensors, to detect obstacles,
maintain boundaries, and clear simulated snow.
The system operates independently, requiring minimal human intervention
while ensuring precise snow removal and obstacle avoidance. At its core, the rover uses an Arduino Due microcontroller
to manage inputs from sensors and execute real-time actions. The integrated system allows the robot to navigate
complex environments, adhere to speed and boundary constraints, and avoid collisions with obstacles. Designed for
reliability and performance, this is a scalable solution for automating snow removal tasks in varied conditions.

How it works
The snow plowing autonomous robot is designed to efficiently clear snow from designated areas with minimal human intervention. Powered by an Arduino Due microcontroller, the robot integrates advanced sensors, including ultrasonic and line-following sensors, to navigate its environment. The ultrasonic sensors detect obstacles, triggering the robot to adjust its path dynamically to avoid collisions, while the line-following sensors ensure it stays within the defined boundaries of the snow-clearing zone. A custom-designed plow mechanism efficiently moves snow out of the target area, guided by precise movement algorithms and motor control. The robot operates at safe speeds, continuously monitors its surroundings, and logs performance data, ensuring a reliable, efficient, and fully autonomous snow-clearing experience.
