2In an ambitious fusion of biology and robotics, a Georgia-based startup is taking the next big step in agricultural automation. Ground Control Robotics (GCR), founded by Georgia Tech researcher Dan Goldman, is introducing legged robotic systems that mimic the movement of arthropods to manage weeds in complex agricultural landscapes. Designed for terrains that stump conventional farm machinery, these robots could provide a game-changing solution for growers of crops like blueberries, strawberries, and wine grapes.
The robots, often likened to giant robotic centipedes, are not just bioinspired imitations of insects—they’re what Goldman calls “robophysical” models. These devices serve a dual role: enabling practical crop management and functioning as experimental tools for studying animal locomotion. According to Goldman, the research behind these robots focuses on how animals navigate through complicated environments, with those findings feeding directly into the engineering of machines robust enough to operate outside of controlled lab settings.
At their core, the robots are relatively simple by robotics standards. Each consists of a sensor-equipped head and several identical, cable-linked segments, each with leg-actuating motors. While this creates a system with many degrees of freedom, it can be controlled using surprisingly straightforward techniques. The result is a machine that “swims” through dense and uneven terrain without requiring complex computing or sensing—thanks to its many legs and a unique design that moves actuation away from the robot’s centerline.
Traditional automation tools are generally designed for well-organized, flat crop fields, which are already being efficiently managed with modern robotics. However, GCR is targeting a much tougher niche: perennial crops growing in rugged, sloped, or rocky areas. These conditions make conventional robots impractical and render manual labor both costly and increasingly scarce. Weed control in such environments can cost upwards of $300 per acre for blueberries, and more than $1,000 per acre for strawberries, especially in pesticide-free operations. GCR aims to offer a cheaper and more sustainable alternative.
A key advantage of the centipede-style robot is its size and flexibility. It can move directly beneath crops without damaging them, unlike larger wheeled or legged machines. According to Goldman, placing the robot closer to the plants while minimizing disruption is essential in cluttered environments where obstacles are on the same scale as the robot. Rather than attempting to model every unpredictable terrain interaction, the robot relies on mechanical design—adding more legs, which provides stability and allows motion without active sensing.
Each leg module is inexpensive, and because most of the system’s functionality is mechanical, the entire robot is cost-effective—potentially priced in the low thousands. This opens the door for scalable use, with swarms of these robots eventually roaming farms 24/7. For now, the focus is on scouting and mapping, but future versions could physically remove weeds using gripping appendages or even targeted lasers.
Pilot programs are already underway, with GCR collaborating with a blueberry farmer and a vineyard in Georgia to refine the robots’ movement and sensory capabilities. While agriculture is the initial focus, the underlying design has potential applications in disaster relief and other fields that require mobility in complex environments.
What makes Ground Control Robotics stand out is not just the novelty of its design, but the practical transition from academic theory to market-ready product. In a field where many robotic concepts remain confined to labs or conferences, GCR’s centipede bots are poised to make a tangible impact in the dirt—literally.
As Goldman puts it, developing a robot that operates effectively outside of the lab required embedding durability and function from the start. With rising labor costs and increasing demand for pesticide-free farming, GCR’s robotic centipedes may soon become an essential tool for modern agriculture.
