What does long-term autonomy mean in robotics?

• A. The ability to operate with direct human supervision at all times.
• B. The ability to operate independently over extended periods without human intervention.
• C. The ability to operate only during daylight hours.
• D. The ability to perform only static tasks.

Answer: (B)

Long-term autonomy means a robot can operate on its own for an extended period without human input. This involves not only carrying out tasks but also managing energy, scheduling actions, diagnosing and handling faults, and adapting to changing conditions in the environment. The essential idea is independent operation over time, without the need for continuous human intervention. Other descriptions that emphasize constant supervision, daylight-only operation, or performing only static tasks don’t capture the ongoing self-sufficiency and dynamic decision-making that long-term autonomy requires.
