    Abstract: The present invention provides a flying robot (10) with projector, including a movable end (100) and a fixed end (200). A distributed working mode is used on the movable end (100) and the fixed end (200). The movable end (100) includes a top (110), a main body (120) and a bottom (130). The top (110) includes a lift system (112) and one or more proximity sensors (114); the main body (120) is a sealed hollow spherical body or spheroid body made of a film material capable of being used as a rear projection screen, and is filled with a gas of which the density is less than that of the air. The bottom (130) includes one or more rear projectors (131), a wireless communication module (132), a microcontroller (133), a battery (134), a direction and steering controlling device (135), a camera device (136), a sound capturing and reproduction device (137), a height sensor (138) and other sensors, etc. The fixed end (200) includes a wireless communication module (220), a control apparatus (240), a charging port (260), and other data interfaces, etc. The flying robot (10) with projector according to the present invention facilitates human-machine interaction and is suitable for being used in both indoor and outdoor environments.

    Abstract: Drones have become ubiquitous in performing risky and labor intensive areal tasks cheaply and safely. To allow them to be autonomous, their flight plan needs to be pre-built for them. Existing works do not precalculate flight paths but instead focus on navigation through camera based image processing techniques, genetic or geometric algorithms to guide the drone during flight. That makes flight navigation complex and risky. We present automated flight plan builder DIFPL which pre-builds flight plans for drones to survey a large area. The flight plans are built for subregions and fed into drones which allow them to navigate autonomously. DIFPL employs distributed paradigm on Hadoop MapReduce framework. Distribution is achieved by processing sections or subregions in parallel. Experiments performed with network and elevation datasets validate the efficiency of DIFPL in building optimal flight plans.

    Abstract: A device can receive, from a set of sensor devices associated with an irrigation system, information that identifies a set of volumetric flow rates. The device can determine a set of pressure loss values based on the set of volumetric flow rates. The device can determine, based on the set of pressure loss values and a first set of moving average pressure loss values, a second set of moving average pressure loss values. The device can determine a subset of sensor devices for which corresponding moving average pressure loss values satisfy a threshold, and determine a subset of locations that correspond to the subset of sensor devices. The device can identify a leak location based on the subset of locations, and provide information that identifies the leak location to permit and/or cause an action to be performed in association with the leak location.
