People who choose to work in the agriculture industry often feel called to it. This occupation is a labor of love and not for the faint of heart. From spacing the plants for optimal growth to preparing the land for harvest, farming requires a great deal of physical exertion and heavy lifting.

Agriculture technology companies have taken note and continue to work toward ways to ease the strain on human workers. The solution? Automating some of the industry’s most labor-intensive tasks. One such task near the top of the list is weeding, and the technology is catching on. Below are examples of three robotics companies that have developed state-of-the-art weeding technology that  help farmers protect their crops.

ecoRobotix
The idea for the AVO weeding robot was born from an intimate knowledge of a necessary pain point. ecoRobotix co-founder and chief technological officer Steve Tanner spent his youth helping his parents weed sugar beets on their farm in Essert-Pittet, Switzerland. Weeding sugar beets was tedious, but Tanner was dismayed to see that hand weeding had been largely replaced by pervasive chemical applications that often harmed the environment.

Chemical treatments do not have a positive image, but they are efficient. And for us, the objective is to reduce the quantities applied.

 – Isabelle Aeschlimann, Marketing & Communication Officer, ecoRobotix

Tanner devised a lightweight, energy autonomous robot that would use artificial vision and precise herbicide applications to weed instead (Figure 1). He connected with fellow entrepreneur Aurélien Demaurex to found ecoRobotix on January 1, 2014. Since then, the AVO weeding robot has been used in Germany, France and Spain on rapeseed, beans, meadows and, of course, sugar beets.

AVO helps to ensure a smaller environmental footprint. It works by identifying flora that are dissimilar to the selected cultivar. It ignores the crops, targeting the weed with a mini dose of herbicide, allowing farmers to use 90 percent less. AVO is solar powered and can run for 12 daylight hours and into the night with the help of two rechargeable batteries. Thanks to a self-service downloadable Android and Mac application, growers can focus on other tasks knowing they will receive an alert if issues should arise.

Naïo Technologies
When developing its weeding technology, Naïo Technologies did not stop at a single robot. The company created three – Oz, Ted and Dino (Figure 2). Each model focuses on a different application. Oz weeds and hoes a plot of land using specialized tools without the need for constant supervision. More than 110 of these robots are already in operation.

Meanwhile, Ted is a multifunctional weeding robot designed for vineyards. This low-impact machine uses camera vision and sensors to position the tools as close to the crop as possible. More than 30 Ted robots are working on vineyards today.

It is important to note that we no longer have to convince people to accept these robots because that work was done five or six years ago. The adoption of robotics on farms is happening now.

 – Anouck Lefebvre, Communication Director, Naïo Technologies

Dino is specially designed for large-scale vegetable farms. This electric weeding robot works on crops like leafy greens, with more than 25 Dino models currently being used in Europe and California.

It seems to be working as a recent customer survey confirmed that those using the robots deemed them user-friendly. All three weeding robots use an advanced GPS navigation system and help farmers manage weeding without herbicides. Naïo also implemented a specialized safety and quality control department dedicated that ensures the robots can do their work without harming human workers or the crops.

VitiBot
Since his childhood, Cédric Bache, CEO at VitiBot has been trying to make vineyard work easier on his father. Vineyards are special cases, as the vine stocks exist close to the machinery and tools. The vines are often planted on steep slopes and inclines. This makes navigating a vineyard a task that requires a lot of experience and rigorous attention to detail. Skilled labor is hard to find.

Bakus had several objectives before it went to market, (including) increasing operator safety, protecting the vineyard and biodiversity, optimizing profitability by working the soil autonomously using a wide range of tools.

 – Michael Fontanin, Director of Marketing and Communications, VitiBot

With an eye to the environment and worker safety, Bache developed a crawler robot named Hector that tackled mechanical weeding, spraying, mowing and stripping. This initial innovation paved the way for Bakus, a completely autonomous vineyard straddler that manages the challenging environment and a wide range of passive tools, including plows, simple sprayers, kress fingers and more.

The weeding robot runs quietly, using 75Kw/h of electric power to navigate the terrain treating existing weeds without herbicide applications. Bakus is currently being used on vineyards in Champagne, France and will soon be used for soil work in the Bordeaux region.
