Abstract: A system for monitoring plants, the system comprising: one or more sound collectors configured to receive and generate signals based on sounds that plants make; and a computer system configured to receive and process the signals to provide a profile of a plant producing the sounds.

Abstract: An agricultural robot for monitoring a growing site, the robot comprising: an autonomous mobile platform; an acoustic sensor module mounted on the autonomous mobile platform and comprising: a speaker operable to transmit a directional acoustic signal at an object; and a microphone operable to register a reflection of the acoustic signal from at least one plant in the growing site; and a sound analyzer operable to time-index the registered reflection, and map a location in the growing site of the at least one plant responsive to the registered reflection.

Abstract: An agricultural robot for monitoring plants in a growing site, the robot comprising: a sensor module comprising: a speaker operable to transmit a directional acoustic signal at an object; and a microphone operable to register a reflection of the acoustic signal; a sound analyzer operable to time-index the reflection received by the microphone and maps a location of the object that reflected the received acoustic signal; and an autonomous mobile platform onto which the sensor module is mounted.

Abstract: A method for distinguishing a target, wherein the target includes one or more objects of interest possibly located among a plurality of objects. The method comprises the following stages: obtaining and processing sonar or radar raw data; tracking the objects of the plurality using the processed raw data; grouping the tracked objects by associating them into one or more groups, while hierarchically arranging the tracked objects in the groups and controllably applying prior knowledge at least about characteristic features and/or constraints of the target's class; classifying the groups to classes and determining whether any of the groups matches to the target's class.
