Trends in Agricultural Robots: a Comparative Agronomic Grid Based on a French Overview
Résumé
Equipment innovation is one of the crucial levers for the improvement of economic, societal and environmental performances of agriculture. In particular, precision farming is expected to be among the 10 technologies that could change our lives. Amid the different technologies enabling a greater precision of agriculture, robotics and sensors could radically change the way of farming. Automatic machines collecting and managing data, eventually feeding a bigdata approach, could provide new tools for fine-tuning farmers’ decision making and help them in mastering the environmental footprint of agriculture. Nevertheless, what is a robot from the agricultural point of view? What are the solutions under development or on the market? How to compare them? The disruptive transformation of the agricultural machinery market requires the definition of new landmarks, especially for agronomists who are facing new opportunities and technologies. We present here the early results of a comparative overview realized by a group of students in agronomy and specializing in agricultural equipment and new technologies at UniLaSalle. The five students were asked to provide figures and a summary of the agricultural robots available in France, either on the market or upcoming. Firstly, they defined what a “robot” is. They referred to Coiffet (2007) who considers “robot” a machine for the human assistance executing a work or a physical task, either as a tool handled during the execution of the task or capable to perform the work without human intervention. Accordingly, the database includes only agricultural machines fulfilling at least two out of the three following criteria: the capability to execute a task, the operational flexibility, the self-adaptability to the working environment. Three robot classes were identified (decision, assistance or substitution) further classified in two agricultural domains and related operational subdomains: crop production (including permanent crops, horticulture, field crop and other crops) and breeding (including cattle, poultry, and pig). Out of a 4 months work, the database finally contains 98 robots from 70 enterprises, with full specifications retrieved from more than 300 websites and 7 French agricultural journals, as well as through the participation to some specialized fora. For comparison, the “Agricultural Robots” report by Tractica highlighted 149 profiles over a comparable time period. Drawing upon a solid background in agronomy, the students analysed the farming operation performed by the listed robots, with a focus on the vehicle-soil interface. Altogether, the design and development of this database can provide agronomists with an up-to-date comparative grid of the existing and upcoming agricultural robots. Identifying clear landmarks in the high pace robot landscape will enhance the agronomic evaluation and enable a clearer understanding of robot relevance for farmers.
