Preemptive Scheduling is a scheduling method where the operating system forcibly interrupts tasks to switch between them based on priority or time slices. While effective in multithreading, it can introduce unpredictable timing, which may be problematic in robotics. Preemptive scheduling contrasts with cooperative scheduling by not requiring tasks to yield control voluntarily. It is commonly used in general-purpose operating systems to manage multiple threads or processes but may complicate synchronization and increase CPU overhead in embedded applications.
