The invention relates to a robotic weeding equipment for agriculture robotic weeding system, comprising: a plant squeezer for squeezing cultivated plants, comprising a narrowing end portion and two longitudinal sides, extending backwards from the narrowing end portion when mounted on the agriculture robotic weeding system; a plant squeezer actuator operably connected to the plant squeezer for vertical displacement of the plant squeezer when mounted on the agriculture robotic weeding system; an image recognition device for identification of weeds; and a weed treatment processing device. The plant squeezer is configured to squeeze two parallel rows of cultivated plants to increase the weeding surface between said two parallel rows of cultivated plants. The invention also relates to an agriculture robotic weeding system comprising at least one weeding equipment, preferably three weeding equipment arranged next to each other along a direction perpendicular to the direction of the agriculture robotic weeding system when operating.

The invention concerns a method using a robot for an automatic treatment of a weed, the method comprises steps of capturing images of said weed with a camera on said robot; determining with said images a distance between the weed and a second vegetable organism; and selecting a treatment tool of said robot for a treatment of the weed from a group of treatment tools as function of said distance. The invention further concerns a robotic vehicle for carrying out the method for an automatic treatment of a weed.

The optoelectronic circuit includes a photoreceptor () made in a silicon semiconductor substrate (), and a monomode VCSEL laser diode () made in a gallium arsenide substrate. The photoreceptor includes at least one photosensitive area with a pixel array for picking up light and an area with a control and processing unit for the signals supplied by the pixels. The laser diode is mounted and electrically connected directly on one part of the photoreceptor. The laser diode is connected by a conductive terminal () to a first contact pad () at the bottom of a cavity () made through a passivation layer () of the photoreceptor. An electrode () on the top of the diode is connected by a metal wire () to a second contact pad () of the photoreceptor. The photoreceptor controls the diode directly via the electrode and the conductive terminal to generate a laser beam (L).
