DURHAM, N.C. (AP) — Researchers at Duke University have developed a groundbreaking robot named Argus, designed to navigate and observe its surroundings from any angle. This innovative machine, equipped with 20 legs and advanced depth-sensing cameras, showcases a unique approach to robotics.
Engineering professor Boyuan Chen and his team created Argus by focusing on dynamic symmetry, which emphasizes uniform movement rather than mimicking the shapes of natural creatures. This allows Argus to operate effectively without a defined front or back, enabling instant movement and observation in any direction.
Argus features a roly-poly design with telescoping legs extending from a central core. This design allows it to navigate challenging terrains, such as sandy beaches and dense forests, while overcoming obstacles and maintaining stability when pushed. The robot can climb between parallel brick walls by alternating its leg movements, showcasing its versatility.
In experimental trials, Argus demonstrated its ability to adapt and continue functioning even if one or more motors fail or a leg breaks. Jiaxun Liu, a graduate student and co-author of a study published in Science Robotics, remarked on the robot’s remarkable movement capabilities, noting, “Watching Argus move is unlike watching any other robot we’ve worked with.”
Researchers introduced a new design principle called dynamic isotropy, which assesses robots based on their ability to accelerate uniformly in all directions. Argus scored an impressive 0.91 on this scale, significantly outperforming most existing robots that typically score below 0.6.
Professor Chen envisions that the principles used in Argus’s design could influence the development of various types of robots, including those used for search and rescue operations, underwater exploration, and aerial vehicles. He suggests a potential for Argus to serve as a multifunctional manipulative tool, stating, “Instead of building a robot hand that looks like a human hand, one idea is to think about having Argus be the hand itself.”
