What is a loop that checks a condition but repeats no commands called?

The term that describes a loop which checks a condition but does not execute any commands is identified as an Idle Loop. This type of loop continuously evaluates a specified condition and can be useful in scenarios where you might want to pause or wait for an event to occur without performing any actions.

For example, an Idle Loop could be used in robotics to check whether a certain sensor has been triggered or whether a particular condition in the environment has been met before proceeding with further actions. Its purpose is essentially to conserve processing resources by not executing unnecessary commands while still keeping the program responsive to changes in state.

Other options, like Active Loop or Conditional Loop, imply the execution of commands or actions based on conditions rather than merely checking them. An Infinite Loop denotes a situation where the loop continues indefinitely without a terminating condition, which is quite different from the concept of an Idle Loop focused on condition-checking without action.
