Autonomous weed whacker to eliminate herbicides

Common practice for farmers is to use chemical herbicides to kill weeds. The global market of herbicides is around $26 billion annually. Regulation will force farmers to pivot towards a more sustainable approach. Team odd.bot believes that only a disruptive robotic solution can tackle this challenge. 


With their Weed Whacker robot called “odd.bot” they aim to save more than 170.000 liters of chemical herbicides in the next seven years. Martijn Lukaart, Founder and CEO, explains that Odd.Bot is currently intended for use in organic farming fields to make the weed-pulling process easier for large farms who currently do all the work by hand.

Many large-scale farmers have already invested in a platform that allows workers to lay face down on a bed as they are propelled through the rows of crops. This provides workers a quicker and more comfortable way to pull weeds manually. However, Odd.Bot’s goal is to work the fields ahead of humans with many advantages for the crops, farmers and workers.

Firstly, Odd.Bot can improve crop yield by tackling weeds early on and continuously. This gives crops more room to grow without competition from weeds, and thus a larger yield. Additionally, Odd.Bot is 100% organic by achieving the task without any chemicals or harm to the plants. Using the robot provides farmers an alternative to the struggles of finding and keeping as many employees.

Odd.Bot works by autonomously roving along rows of crops, propelled on heavy-duty tires. A mechanism in the center of the robot then extends down to extract weeds as it moves. Cameras and sensors keep the robot on task and away from growing crops, regardless of row width. The robots can be rented to clear fields for a jumpstart to the growing season or as helpful “hand” as crops mature.

In addition to reducing the manual workload and minimizing the need for gas-guzzling tractors that pollute the environment, Odd.Bot also hopes to move into the traditional farming market where they can influence a diversion from traditional herbicide usage. On the company website, they state, “With our Weed Whacker we aim to save more than 170.000 liters of chemical herbicides in the next seven years.”

By making organic farming more profitable, Odd.Bot also hopes to directly or indirectly contribute to providing healthy food at reasonable costs.
