AI Weeder Innovation Unveiled by University of Idaho

Researchers from the University of Idaho Coeur d’Alene have showcased a groundbreaking autonomous robot powered by artificial intelligence (AI) that effectively eliminates weeds. The robot, measuring three feet wide and equipped with wheels, leverages AI to scan, identify, and target weeds as small as half an inch. Upon identification, the robot administers an electric shock to eradicate the weed.

The successful demonstration took place at the U.S. Forest Service’s Coeur d’Alene tree seedling nursery. Moving forward, the team plans to enhance the robot by developing a weather-resistant casing for its hardware, upgrading its electrical components, and refining the AI's weed recognition accuracy. Data collection and testing will continue throughout the next year, marking a significant step in advancing reforestation efforts.

In collaboration with the U.S. Department of Agriculture (USDA), the University of Idaho is spearheading the development of this robotic system as part of the Project Evergreen initiative. The goal is to optimize reforestation within the national forest system overseen by the Forest Service. By reducing labor costs, dependence on pesticides, and fossil fuels through autonomous weed eradication, the project aims to bolster local flora and enhance reforestation endeavors.

Weed control at the Coeur d’Alene nursery, one of six maintained by the Forest Service across the country, incurs an annual expenditure of $500,000 predominantly allocated to manual weeding. By minimizing weed growth, seedlings can access vital soil nutrients, resulting in healthier plants, reduced operational costs, and improved reforestation outcomes.

The Forest Service plays a pivotal role in expanding reforestation efforts in accordance with the REPLANT Act, a part of the 2021 Infrastructure Investment and Jobs Act. By planting over 1.2 billion trees across 4 million acres of U.S. forests within the next decade, the agency endeavors to meet the mandate of the REPLANT Act.

The collaboration between the University of Idaho and the Forest Service holds promise for both parties. Not only does the university have the expertise and resources to develop cutting-edge machines, but it can also train a new generation of students proficient in intelligent robotics. For the Forest Service, this partnership aligns with the agency's commitment to the REPLANT Act, fostering sustainable forest management and delivering substantial benefits to the public.
