Rayser is a precision laser weed control device. This energy-saving and soil-friendly device can complement or replace herbicides. It is intended to be attached to a mobility vector, such as a tractor or a robot.

Rayser has been designed to be small, light, energy efficient and fast to operate, to tackle intra-row weeds efficiently.

How it works ?

Rayser will detect weeds in the row using a camera, then a system of mobile mirrors will make it possible to target weeds where they are most fragile, in order to destroy them quickly while consuming a minimum of energy and without disturbing your soil or damaging your crops.

Artificial intelligence

Rayser uses Artificial Intelligence (AI) to distinguish weeds among crops. Our AI is continuously improved through a three-step process.


We train machine learning algorithms on annotated images so that our AI learns to recognize weeds more and more efficiently.

We collect numerous images in the field in order to constitute an important bank of photos of all types of weeds and crops in real conditions.

On our image annotation platform, experts will locate and identify the different weeds and crops that appear in the photos.
