This stage may, for example, contain collision detection, speed-up techniques, animations, force feedback, etc.
en.wikipedia.org Its two main components are a rigid body dynamics simulation engine and a collision detection engine.
en.wikipedia.org They are prone to getting stuck, sometimes irretrievably, on objects in the environment owing to a lack of adequate collision detection.
en.wikipedia.org Fuses only sense overcurrent, or to a degree, over-temperature, and can not usually be used independently with protective relaying to provide more advanced protective functions, for example, ground fault detection.
