Robots are Precise
Robots do exactly what you tell them to do. If a robot doesn't quite do what you planned in your pseudocode, it may mean that your instructions weren't quite right. Using precise measurement to program movement is critical for a robot to successfully complete a task.
Surgical robots must have pinpoint accuracy in order to treat certain areas while avoiding others.
Robots that need to complete a series of movements must make each of those movements precisely. An error in robot movement accumulates and increases dramatically with each subsequent movement.
Assembly robots must be continuously precise in order to guarantee the quality of the product they are helping to manufacture.
