Introduction
Red Imported Fire Ants (RIFA) are one of the most invasive and destructive pests globally, causing significant ecological and economic damage. With their ability to spread rapidly and outcompete native species, it’s essential to develop effective methods for detecting and controlling RIFA populations. In this article, we’ll explore a groundbreaking approach using a robotic dog and artificial intelligence (AI) to enhance the detection of invasive fire ant nests.

A collaborative team of researchers from China and Brazil has developed an innovative method using a robotic dog and artificial intelligence (AI) to detect and control nests of the Red Imported Fire Ant (RIFA). The research, published in the journal *Pest Management Science*, showcases how the integration of Xiaomi’s ‘CyberDog’ robot with an AI model allows for the automated identification and monitoring of these invasive ants.
Field tests conducted by the team demonstrated that the robotic system is far superior to human inspectors, identifying three times as many RIFA nests with enhanced accuracy. Eduardo Fox, a postdoctoral researcher at the State University of Goias in Brazil and a corresponding author of the study, elaborated on the advantages of this approach:
“Fire ant nests are difficult for untrained personnel to identify and confirm in the field, and searching large areas can be time-consuming and exhausting under the hot sun. A robot could automatically locate the nests without requiring specially trained individuals and operate at various times of the day regardless of temperature conditions.”
The Threat of RIFA
Red Imported Fire Ants, introduced accidentally to the United States in the 1930s, have spread to regions including China, Japan, and Europe, where they cause significant ecological and economic damage. Fox emphasized the urgency of detecting RIFA nests, explaining:
“RIFA proliferate rapidly in established areas, displacing local fauna and flora by outcompeting and eliminating sensitive species. Small vertebrates, such as birds and reptiles, are particularly vulnerable. Additionally, RIFA associates with significant agricultural pests like mealybugs and can damage some plants, exposing them to pathogens.”
Traditional methods for controlling RIFA populations typically involve the use of pesticides, which can harm local ecosystems. Effective management of these invasive ants requires targeted control strategies that minimize collateral damage to native species, making comprehensive monitoring of ant populations crucial.
Training and Testing the CyberDog
To enhance nest detection, the research team integrated the CyberDog with a machine learning model trained on a dataset of over 1,100 images of RIFA nests. The resulting system achieved a detection precision rate exceeding 90%.
During field trials, the CyberDog was programmed to press its front paw on suspected nests. If the mound was active, worker ants would emerge aggressively from openings in the soil, enabling the robot to distinguish active nests from abandoned ones or those inhabited by other species. Hualong Qiu, a researcher at the Guangdong Academy of Forestry in China and a corresponding author of the study, described the testing process:
“A group of students received official standard training for quarantine inspectors and were tasked with locating fire ant nests in an open field. Subsequently, the AI-trained robot was challenged with the same field, and the performances of the students and the robot were compared.”
Challenges and Future Prospects
While the results are promising, the researchers acknowledge obstacles to scaling up the technology. Zheng Yan, a researcher at Lanzhou University in China and another corresponding author, pointed out:
“The primary limitations to scaling the use of robots are their battery autonomy, which lasts about 30 minutes, and the high cost of acquiring more agile and efficient models.”
Yan added that although the current costs of using the robot system are higher than traditional methods, there is potential for cost optimization in the future.
Raising Public Awareness
Beyond its practical applications, the study highlights the potential of robotic dogs to raise public awareness about the dangers of invasive fire ants. Yan noted:
“In addition to being versatile machines for navigating urban environments, robot dogs attract a lot of public attention. Fire ants pose a serious threat in China, yet most people remain unaware of the dangers of invasive fire ant nests in public areas. Therefore, sightings of robots tracking fire ant nests are likely to captivate the public and raise awareness about the presence of fire ants.”

Conclusion
The integration of AI and robotic dogs has the potential to revolutionize the detection and control of invasive fire ant populations. While there are challenges to overcome, the benefits of this approach far outweigh the costs. As public awareness of the dangers of invasive fire ants increases, it’s essential to continue developing and refining this technology to protect ecosystems and economies worldwide.
