It can help people easily clean up daily garbage and dirt at thebottom of swim ming pool, completely changing the previous manual cleaning way, so that the cle aningwork becomes no longer troublesome. In order to realize the function of au tonomously cleaning underwater, in addition to good water-proof performance, th e robot also needs a pair of “eyes” capable of routerecognition, and this pair of eyes are path navigation systems thereof. Generally, such kind of navigationsystem uses a measurement manner in which an acceleration sensor and a gyroscope are combined toacquire a trajectory of a moving object, so as to control the m ovement trend thereof.
