Rotator

A rotator is a mechanism or muscle that facilitates rotational movement. It is typically used in contexts where turning or spinning is essential. Rotators can be found in various applications, ranging from mechanical systems like engines and gears to biological systems such as the human body and animals. Their primary function is to control or produce angular motion, allowing for changes in orientation and position, or for moving a part of the body in a circular motion. Understanding rotators' function is key to understanding the mechanical or physiological processes at play. The term highlights the ability to cause or enable rotation.

Rotator meaning with examples

• The robotic arm utilized a sophisticated rotator to precisely position the welding tool, enabling complex manufacturing tasks. The rotator allowed for 360-degree movement, increasing precision and speed of operations, making it ideal for this task. Without it, the robot would lack the capacity to turn freely or correctly position itself. This is a central component to the robot's design.
• During physical therapy, the therapist worked to strengthen the patient's shoulder rotators after an injury. These muscles were crucial for regaining a full range of motion. Regular exercises with an elastic band target the rotators. This rotator rehabilitation helped stabilize the shoulder joint and improve overall functionality to help the patient heal.
• The car engine's crankshaft acts as a rotator, converting linear motion from the pistons into the rotational force necessary to turn the wheels. The rotator, driven by pistons, allows for torque production and powers the whole system, ensuring the car's movement. The engine's rotator is vital for transportation.
• In a wind turbine, the blades are connected to a rotator, which harnesses the wind's energy to generate electricity. The rotator transforms the linear force of wind into rotational force, powering a generator. The faster the blades rotate, the greater the efficiency, highlighting how a good rotator design can allow for increased electricity production.
• The biologist studied the specialized rotator in the chameleon's eye, enabling the animal to maintain a wide field of view by moving their eyes independently. The rotator allowed independent eye movements, increasing the ability to focus. This adaptation provided a significant advantage in hunting, highlighting its function.
