Abstract: Disclosed herein is a method of detecting stalled state of a dynamic pool equipment unit, comprising receiving a plurality of movement features relating to a dynamic pool equipment unit deployed in a water pool which are captured during a predefined sampling window and comprise (1) motion features of the pool equipment unit, and (2) operational features of electric motor(s) of the pool equipment unit, determining a movement pattern of the pool equipment unit using one or more statistical models applied to the plurality of movement features which are trained to estimate a stalled state of the pool equipment unit in which the pool equipment unit is pitched up and unable to advance on a slopped obstacle in the water pool, and causing the pool equipment unit to stop attempted advance in a current direction responsive to determining that the pool equipment unit is in the stalled state.

Abstract: A method of evaluating slipperiness of a floor surface of a water pool by inducing one or more rotation scans of a pool equipment unit by driving a power pulse to one or more electric motors configured to rotate the pool equipment unit deployed on a floor surface of a water pool and at least partially submerged in water of the water pool, accumulating power values of the power pulse while its level is above a motor operation threshold, accumulating values of angular velocity of the pool equipment unit measured starting after the power pulse drops below the threshold until the pool equipment unit stops rotating; computing work energy invested to rotate the pool equipment unit based on the power values and the angular velocity values; computing a slipperiness index of the floor surface based on the work energy; and initiating one or more actions according to the slipperiness index.

Abstract: A method for navigating a movable pool related platform (PRP), the method includes moving the movable PRP along a home direction, wherein the movable PRP is associated with a gyroscope and with a magnetometer, wherein the moving is based on a gyroscope-based direction of movement estimate, wherein the gyroscope was aligned with the magnetometer. The magnetometer was calibrated during a calibration process that includes (i) determining, by a controller of the movable PRP, a mapping between magnetometer readings and a magnetometer-based direction of movement estimate; wherein the mapping is based, at least in part, on a first range of the first axis magnetometer readings and a second range of the second axis magnetometer readings; and (ii) performing an alignment iteration that comprises aligning, by the controller, between the magnetometer-based direction of movement estimate and the gyroscope-based direction of movement estimate.
