Duke Researchers Build Argus Robot for All-Direction Movement
The 20-legged robot uses dynamic isotropy to move equally well in any direction and keep working after leg or motor failures.
- Duke University researchers unveiled Argus, a robot featuring 20 modular, telescoping legs arranged radially around a central core, designed to move in any direction instantly.
- Researchers published a design principle called dynamic isotropy in Science Robotics, which rates robots on a 0 to 1 uniformity scale; most modern systems score below 0.6, while Argus reaches 0.91.
- Jiaxun Liu, a Ph.D. student, helped develop the system, which navigates sand and forest trails while carrying a 10-pound payload and climbing vertical walls.
- Professor Boyuan Chen, who directs the General Robotics Lab, envisions the technology guiding search and rescue robots and aerial vehicles. "We want robots that help us learn things about the world we couldn't learn any other way," Chen stated.
- A large-scale simulation sweep of over 1,500 morphologies accompanies the research, enabling further exploration of the design space and positioning Argus as an early demonstration of direction-agnostic robot design.

Duke scientists create robot from your nightmares: 20 legs, eyes everywhere, no front or back
A robot being developed at Duke University is almost ready to face the world, in any direction. Instead of trying to copy symmetrical shapes from nature by building robots that look like people, dogs or insects, engineering professor Boyuan Chen and his team focused on uniformity in action, or what he calls “dynamic symmetry.” The result was Argus. The roly-poly robot named after a mythological many-eyed giant has depth-sensing cameras attached …
20 legs enables all-direction motion freedom to Argus robot
Researchers at Duke University have developed a novel robotic system that challenges traditional design principles by prioritizing uniform motion in all directions over human-like form. Guided by this concept, the team simulated more than 1,500 robot configurations to identify a design close to their theoretical performance limit. The resulting robot, named Argus, has no defined front or back and features 20 modular, telescoping legs arranged ra…
