open loop
This term is primarily used in engineering, robotics, and systems theory to describe a process that operates blindly. It implies a lack of sensory input or monitoring, where the system assumes the desired result is being achieved without actually verifying it. This creates a contrast with closed loop systems, which use feedback to make real-time corrections.
In a practical sense, an open loop is characterized by simplicity and lower cost but lacks precision and adaptability. It is typically used in environments where the variables are highly predictable or where the cost of adding a feedback sensor outweighs the benefit of increased accuracy.
