Which statement about autonomous UGV capabilities is most accurate?

• A. They require constant human navigation input
• B. They can operate without human nav input
• C. They can only operate in daylight
• D. They can only operate on paved roads

Answer: (B)

Autonomy means the vehicle can navigate and make decisions on its own using onboard sensors, mapping or localization, and planning algorithms. An autonomous UGV uses sensors such as cameras, LiDAR, radar, and IMUs to understand its environment, localize itself, plan a safe path to a goal, and execute control commands without needing someone steering in real time. It can adapt to obstacles, replan routes, and continue missions with minimal or no human navigation input, though a supervisor may still set goals or monitor performance.

That’s why the statement about operating without human navigation input is the best fit. The other ideas are too limiting: constant human input describes teleoperation, not autonomy; many autonomous systems can operate under varying lighting conditions, including night, and on non-paved terrains depending on their design and sensors.
