  • Patent number: 10602665
    Abstract: 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.

  • Patent number: 10420279
    Abstract: 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.

  • Patent number: 10172289
    Abstract: 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.

  • Publication number: 20160250756
    Abstract: The invention relates to a gripping device (5) comprising a gripping member (10) designed to come into contact with an object to be manipulated (100) and control means for controlling a joining and a separation of the gripping member and the object to be manipulated, the control means being associated with a contact (16) able to generate a joining and/or separating control signal intended for the control means when the contact is activated. According to the invention, the gripping member is slidably mounted in the device between a non-pushed-in position and a pushed-in position, the contact being positioned in the device so as to be activated by the gripping member when the gripping member is in the pushed-in position. The invention also relates to a co-handling robot comprising such a device.

  • Publication number: 20100019709
    Abstract: The invention relates to a method for controlling the electric motor of a hybrid or electric vehicle. The method is intended for controlling the electric motor driving the transmission shaft of a vehicle, wherein the motor applies to the transmission shaft a torque having a value corresponding to a torque set-point applied to said electric motor. The torque set-point is corrected by subtracting a correction signal obtained by the application of a band-pass filtration-type processing to a signal representative of the transmission-shaft rotational instant speed, within a frequency band including the frequency of a particular oscillation mode of the vehicle traction chain. The invention can be used for reducing jolts resulting from a discontinuity in the torque applied to the transmission shaft.
