Évaluation d'un outil robotique pour le désherbage et le suivi des cultures bio-intensives

Abstract : Weeding is a key issue in organic agriculture, especially in the organic market gardening agriculture. Farmers are not allowed to use chemical solutions to take out the weeds, they can only use mechanical and thermic solutions in their exploitations. Farmers say that the weeding process is one the most time-consuming task in the maintenance job. Weeding causes physical pain to the farmers, is labor intensive and is considered a very tedious task. A solution to this problem would be to set robots in farms to do the weeding part. Robots could weed by using technics respectful of the rules of the organic agriculture. Peter Hanappe and David COIliaux, researchers at the Sony CSL laboratory are creating a robot, called LettuceThink, that can weed beds of market gardening cultures. This robot can determine the location of the vegetable and weed around the plant thanks to an animated arm. In this dissertation are presented the results of experiments created to put to test the efficiency of the robot. Efficiency is here defined as the ability of the robot to weed in the real conditions of use. Those conditions include the diversity of weeds existing in a market gardening farm, the diversity of cultivated plants and of weather conditions. In the second part of this dissertation, I present the results of discussion that I had with market gardening farmers. The two major subjects of the discussions were their technics of weed management and the possible interest of the robot LettuceThink in their farm. The aim of these talks was to understand the need of professional market gardeners in terms of robotization and to figure out hoW the robot will be able to meet this need. The experiments and the discussions enabled us to find important ideas to improve the robot in terms of mechanics and algorithmic.
