1. What is the conceptual origin?The theoretical groundwork for driverless tractors was laid around 1940
2. What is the core navigation system?Relies heavily on Global Navigation Satellite Systems (GNSS) for precise geospatial positioning
3. How does a driverless tractor know where to go?It uses GPS for its position, plus extra tools like an inertial measurement unit and wheel encoders to stay on track even when GPS is weak.
4. What sensors help the tractor see its surroundings?The tractor uses cameras to see field borders, lidar to build 3‑D maps, and ultrasonic sensors to detect nearby objects.

Unmanned Ground Vehicle (UGV): A robotic vehicle capable of operating without a human driver on the ground.
Precision Agriculture: Farming management based on observing, measuring, and responding to inter- and intra-field variability in crops.
Lidar: A remote sensing method that uses light in the form of a pulsed laser to measure distances to the Earth's surface.
