What file type dictates a robot's movement sequence to designated points in its working area?

The key to understanding the correct answer lies in the definition and function of a program file in the context of robotics. A program file contains the specific instructions and commands that dictate how a robot operates, including its movement to designated points within its working area. This file is crucial as it encompasses the logic and sequences that the robot follows to execute tasks efficiently.

In addition, a program file typically includes the algorithms and detailed movement paths necessary for navigation and task completion, which enables the robot to execute its functions autonomously. This contrasts with other file types, which do not specifically contain movement instructions.

For instance, a script file might contain a series of commands typically used for automation tasks but doesn’t necessarily define robotic movements in a structured sequence. A config file is usually associated with configuration settings or parameters but does not dictate actions or movements. A task file might reference certain tasks the robot must perform, but it does not provide the comprehensive detail on the movement sequences required to reach those tasks.

Thus, the program file is uniquely positioned as the file type that encapsulates a robot's movement sequence to designated points in its working area, making it the correct answer in this context.
