Final answer:
The statement is true; robots and programs in general check the value stored in a variable and use it during their execution. Variables act as containers for data values that can alter the program's behavior.
Step-by-step explanation:
When a robot reaches a variable in the program, it does check the value stored in the variable and uses it in the program. This is a fundamental concept in programming and is true. Variables are placeholders or containers for data values that can be changed throughout the execution of a program. The value a variable holds can dictate how the robot or any program behaves, by influencing decision-making processes or controlling iterative operations. For example, if a variable named speed is used to control the velocity of a robot's wheel, the robot's actual velocity will change according to the value assigned to speed at any given moment in the program's execution.
