liikekompensointia

Liikekompensointi, known in English as motion compensation, is a technique used in various fields, particularly in marine operations and robotics, to counteract unwanted movements. The primary goal is to maintain a stable platform or tool relative to a fixed point or a moving target, despite the disturbances caused by factors like ocean waves, vessel motion, or vibrations.

In marine environments, liikekompensointi is crucial for operations such as offshore drilling, construction, and subsea installations. Ships and platforms are constantly subjected to the heave, pitch, roll, and yaw motions induced by waves. Without compensation, tools like drill strings or remotely operated vehicles (ROVs) would experience significant erratic movements, making precise control impossible and potentially leading to damage or mission failure. Liikekompensointijärjestelmät use sensors to detect these motions and actuators to generate counteracting movements, effectively stabilizing the equipment.

Robotics also employs liikekompensointi to enhance precision and performance. For instance, in manufacturing or surgical robotics, unwanted vibrations or external disturbances can compromise the accuracy of robotic arms. Liikekompensointi helps to isolate the robotic end-effector from these disturbances, ensuring that it follows its intended path with high fidelity. This can involve active feedback loops that adjust the robot's movements in real-time. The underlying principle across all applications is to actively measure unwanted motion and then apply an opposing force or displacement to nullify its effect.
