How can you tell that the robot is at the Command Position?

The indicator that signifies the robot is at the Command Position is that the cursor stops blinking. This cessation of blinking indicates that the robot has completed its input stage and is now ready to accept commands in a stable state. When the cursor blinks, it typically signifies that the system is waiting for user input or processing data. Therefore, when the cursor stops blinking, it reveals that the robot has reached a state where it is ready to execute commands, confirming it is at the Command Position.

While other options may indicate various operational states of the robot, stopping the cursor from blinking is a specific and clear signal of readiness for command entry. It is a direct indication tied to the user's interaction with the robot, making it the most relevant answer regarding identifying the Command Position.
