Abstract: Described is a method of controlling movement of a mobile robot in the event of a localization failure. The method comprises, on an occurrence of the localization failure, receiving an image from an image sensor of the mobile robot. The method includes splitting received image into at least two vertical portions and determining if one of said at least two vertical portions is indicative of a passable path. The method includes controlling the mobile robot to travel along the passable path indicated by a selected one of said at least two vertical portions.

Abstract: The present disclosure relates to methods and systems for selection of synchronization targets. Embodiments of the present disclosure provide for selecting a synchronization target for a network device, within operational network constraints, when the network device loses its current synchronization target. When a network device loses its current synchronization target, the stratum index of the network device is downgraded to an artificial stratum index before a selection of a new synchronization target is made. The artificial stratum index is broadcast to children network devices. Downgrading the stratum index to an artificial stratum index allows for selection of available synchronization target network devices with stratum indices higher than or equal to the network device's stratum index. After selection of a new synchronization target, the network device's stratum index is updated, and the new updated stratum index of the network device is broadcast to the children network devices of the network device.
