Cornell team wins robotics challenge

By Blake Jackson

A team of undergraduate students from Cornell University has won top honors at The Farm Robotics Challenge for creating an innovative robot that controls weeds using electricity. The competition included 95 teams, making their achievement highly impressive.

The robot is designed to work independently in vineyards and orchards. It travels through fields without human assistance and destroys weeds by applying a small electric charge. This method reduces the need for chemical herbicides and lowers labor costs, making it an environmentally friendly solution.

Led by Andrew James, an agricultural sciences student, the team spent four months studying existing weed control technologies and building their own energy-efficient prototype. The group combined knowledge from agriculture, engineering, and technology to create a practical system. Natalia Kurz, a team member, described their hard work, saying, “There were fears for us, like, was it just going to be for nothing?”

After winning the competition, the team received a prize of 50,000 dollars. They are now using this funding to start a company called Rootline Robotics. The startup will continue developing the robot and improving its performance.

Weeds are a major problem for farmers because they compete with crops for water and nutrients. This can reduce crop yield and quality. Traditional methods like mowing and trimming require a lot of labor and time. Existing electric weeders are expensive and need operators, making them less accessible to farmers.

Local farmers, like Steve Selin, supported the project by providing feedback during development. He explained how controlling weeds early in the season could protect crops and improve soil health.

The robot was developed with help from experts and students with different skills, highlighting the importance of teamwork. As Kurz said, “Robotics is many different systems in one,” showing how different fields of study must come together.

The team plans to test and improve their robot further before launching it in the market. Their invention represents a step forward in sustainable farming and smart agricultural technology.
