Which control method is described as a fixed sequence of tasks carried out by a robot or UA without real-time human input?

• A. Preprogrammed Control
• B. Autonomous Control
• C. Remote Control
• D. Supervisory Control

Answer: (A)

The main idea here is a system operating from a prepared set of steps without live input from a person. This is preprogrammed control, where a program outlines each task and the exact order to perform them, and the device simply follows that script during execution. Because there is no real-time human input, the sequence is fixed and unchanging unless the program itself is modified in advance.

Autonomous control can run without real-time input too, but it uses onboard decision-making to adapt to what it senses, so the sequence isn’t strictly fixed. Remote control requires a human to steer the vehicle in real time. Supervisory control involves a human guiding at a higher level while the system performs the tasks, not a rigid, scripted run. For a drone to execute a set of actions exactly as written with no live input, preprogrammed control is the fit.
