Autonomous motion is motion that ___

• A. Was named after an automobile.
• B. Is dependent on human intervention.
• C. Allows a robot to interact with its environment, make decisions, and operate on its own.
• D. Does not require any decision making.

Answer: (D)

Autonomous motion means a robot can sense its surroundings, decide what to do based on that information, and carry out actions all by itself, without needing a human to drive every step. This involves sensing the environment, interpreting what those sensations mean, planning a sequence of movements, and executing them with feedback to adjust as things change. That’s why the best description is that it allows a robot to interact with its environment, make decisions, and operate on its own.

The other ideas don’t fit as well: autonomy isn’t about being named after a car, and it isn’t simply the absence of human intervention. It also isn’t about having no decision making—autonomous motion relies on decision making to choose actions in real time and adapt to new situations.
