A robotic system for use in agriculture includes at least one tool-holding arm to hold an agricultural tool and capable of being controlled to enable the agricultural tool to be raised or lowered, a sensor for measuring the height of crops, and a computer to determine a set value for controlling the at least one tool-holding arm on the basis of measurements taken by the sensor for measuring the crop height. The tool-holding arm is connected to a connection member such that it can be mounted on a control arm provided on an agricultural vehicle. The computer can determine a set value for controlling the control arm to enable the tool-holding arm to be raised or lowered on the basis of measurements taken by the sensor for measuring the crop height.

Two armed robotic system for adjusting the height of an agricultural tool

The invention relates to a system for adjusting the height of an agricultural implement, including an arm that can be controlled so as to raise and lower the implement; a height measuring sensor mounted on the arm and positioned in front of the implement in the direction of travel of the vehicle equipped with the arm. A calculator configured to provide a control set point for the height of the arm on the basis of the measurements obtained by the sensor, wherein the sensor is a light screen device formed by an emitter in the form of a column of light sources and a receiver in the form of a column of photoreceptors. The emitter and the receiver are mounted on the arm facing one another and extending along their longitudinal axis, perpendicularly to the ground, in order to measure the height of plants located therebetween.

System and method for the automatic adjustment of an agricultural implement using a measuring light screen

The invention relates to a system for adjusting the height of an agricultural implement, including an arm that can be controlled to raise and lower the implement, a height measuring sensor, and a calculator configured to provide a control set point for the height of the arm on the basis of the measurements obtained by the height measuring sensor. The height measuring sensor is an imaging system including at least one camera mounted such that the sensor can form an image of a scene located in front of the agricultural implement in the direction of travel of the vehicle equipped with the arm. A computer processing unit is configured to produce, on the basis of the images delivered by the at least one camera, a 3D reconstruction representative of the depth of the aforementioned scene.
