Abstract: A method of managing a fleet of information carrier vehicles is provided with each of the vehicles being autonomous in energy and arranged to move and roll on a ground of a field. Each of the information carrier vehicles includes a data communicator for communicating data to a communicating access point common to the fleet of information carrier vehicles, and a tool for performing a work. The method includes, at vehicle level: generation of data of interest, optionally locally preprocessing of data of interest, recording data of interest or pre-processed, transmission of recorded data, movement commands reception and applying the received movement commands. The method includes, at a remote processing device for the vehicles: processing received data to determine a strategy for controlling the vehicle fleet, and communication to the fleet vehicles of movement commands determined from the driving strategy.

Abstract: A robot includes a first axle and a second axle. A first axle housing includes a first transversal axle connected to a rigid structure by a hinge having a first degree of freedom in rotation around a first axis which is vertical and a second degree of freedom in rotation around a second axis which is perpendicular to the first axis and to a first transversal axis. The first transversal axle is equipped on either side with a motor, each motor having a stator and a rotor rotatably mounted to a respective wheel to provide steering and propulsion functions.

Abstract: A process for tending an agricultural estate, in particular a vine-growing or arboricultural estate, includes: defining at least one limited working perimeter (10), and carrying out a tending operation within the limited working perimeter (10) with at least one working device that is autonomous and able to recognize the limits of the limited working perimeter (10), and allowing the autonomous working device to move randomly within the limited working perimeter (10).
