Innovative Robot Coyotes Tested by US Army to Enhance Airfield Safety

The U.S. Army Engineer Research and Development Center is exploring an unusual approach to wildlife management at military airfields. Instead of using conventional methods, they are employing robot coyotes to prevent hazardous bird strikes.

This innovative project addresses a significant safety concern for aviation. Wildlife poses a persistent threat on runways, where birds, rabbits, and even deer can create dangerous situations for aircraft and crew members. Among these, birds represent the greatest risk, with the potential to cause catastrophic engine failures if they collide with planes. In fact, the U.S. Civil Air Administration previously developed a device known as the “chicken gun” to test the resilience of aircraft against bird impacts.

Traditional Deterrents and Their Limitations

For years, airports and airfields have relied on various techniques to deter wildlife. These strategies often include the use of drones, trained dogs, falcons, and gas-powered cannons. However, as wildlife becomes increasingly accustomed to these methods, their effectiveness tends to diminish over time.

The Rise of Robot Coyotes

Responding to these challenges, the Army’s ERDC, in collaboration with wildlife biologists Stephen Hammond and Jacob Jung from the USDA National Wildlife Research Center, embarked on a five-year journey to develop robot coyotes. The foundational idea centers on the natural aversion many animals have toward coyotes. By leveraging this instinct, the robot coyotes aim to keep wildlife at bay near airfields.

The prototype, named Coyote Rover, initially was built using Boston Dynamics’ Spot robots. However, the Spot robots lacked the speed necessary to effectively scare off wildlife. The project team then transitioned to four-wheeled Traxxas X-Maxx motorized vehicles, which can achieve speeds of up to 20 mph. Each of these vehicles is equipped with a realistic plastic coyote dummy, designed to instill just the right amount of fear in nearby wildlife, all at a cost of approximately $3,000 each.

Promising Field Trials

The robot coyotes have undergone testing at several military airfields, including Naval Air Station Pensacola, Fort Campbell, and Naval Air Station Whiting Field. The preliminary results from these trials have been encouraging, as the robot coyotes successfully deterred birds and other animals, contributing to safer and clearer runways.

Future Developments in Robot Coyote Technology

Looking ahead, the ERDC aims to enhance the capabilities of these robot coyotes. Plans are in motion to develop smarter versions that include programmed navigation routes and exclusion zones. Additionally, future models may possess the ability to identify specific species of birds, allowing for a more tailored approach. Imagine robot coyotes equipped to recognize flocks of geese and adjust their tactics in real-time.

Advancements and Autonomous Operations

The partnership between the ERDC and USDA-NWRC continues to refine these robot coyotes for their intended purpose. Exciting enhancements are in store, such as the integration of onboard computers, artificial intelligence, cameras, and sensors. These advancements aim to create a robust, fully autonomous system capable of navigating diverse terrains and adapting to various conditions. Such innovations could fundamentally change how airfields, as well as commercial airports, manage wildlife threats.

A Vision for the Future

The introduction of robot coyotes represents a significant step forward in wildlife management at airfields. By merging technology with biological instincts, the Army is paving the way for safer air travel. As these systems evolve, they may soon extend beyond military applications to airports across the globe.

This advancement raises an intriguing question: If robot coyotes can effectively keep wildlife away from runways, what other innovative animal-inspired robotic solutions could we see in the future guarding our critical infrastructure?
