Abstract: A method of working a plot of land by at least one autonomously and independently operating agricultural robot including, during or after an assessment and planning stage, at least one preferred headland portion specifically intended for input supply and in which at least one supply station for at least one input is located, with the ability to move or reposition within this portion, the at least one robot heading towards this portion when a supply instruction is received or generated by it.

Abstract: A method for working a plot of land by two autonomous agricultural robots, the method including: for one robot in question arriving at the end of a row, and likely to find itself in a waiting situation, completing the work in progress in the main field in its current row, by bringing its tool or tools to the end of the row and therefore to the edge portion in question of the main field, projecting into the headland portion adjoining this edge portion, then in moving backwards in the main field, at least until the robot and its tool or tools are once again located entirely in the main field, in remaining in place and then in resuming the rest of its work on the plot.

Abstract: A method for working a plot of land simultaneously by agricultural robots in accordance with instructions and/or commands transmitted by a common central management and control system, the method including: subdividing the plot of land to be worked into distinct work zones as strips having respective ends at the two opposite extremities thereof, and into a turn zone extending along the various opposite ends of the trips; subdividing each turn zone into turn portions, each of which faces and continues from one of the two ends of one of the strips forming work zones; and assigning a fraction of a turn portion to the robot that either is about to pass or is in the process of passing through the designated turn portion, or is going to start, is in the process of completing or going to complete work in the work zone associated with the designated turn portion.

Abstract: A device for controlling a piece of agricultural machinery that is movable within an agricultural plot includes: a piece of machinery and a unit having a memory including input data for mapping a risk area located within an agricultural plot. The memory includes data representative of a set of types of risk area and data representative of a set of specific behaviors. The unit is configured to: associate the input data for mapping a risk area with a category, associate the category with a specific behavior of the piece of mobile agricultural machinery, and control the specific behavior if the position of the piece of machinery is located in or near the risk area. The piece of machinery is arranged to move autonomously within the agricultural plot according to the specific behavior controlled by the unit.

Abstract: A method for working a plot of land simultaneously by at least two agricultural robots operating autonomously and independently, in accordance with instructions and/or commands transmitted by a common central management and control system, includes subdividing said plot of land to be treated into at least two distinct work zones and allocating each work zone exclusively to one of the agricultural robots. At least during the working phase, the width of the majority of the work zones is equal to a multiple, greater than or equal to 1, of the working width of the agricultural robot to which it is exclusively allocated. During work on a plot of land, work zones not yet worked are exclusively allocated to various agricultural robots, respectively, in a gradual manner according to the completion of the work undertaken by the agricultural robots in the various zones allocated to them.
