In the U.S., researchers have created a 20-legged robot named Argus that can move in any direction
Researchers at Duke University have developed a new robot called Argus, which has 20 telescoping legs and is capable of moving in any direction without a defined front or back.
This was reported by Interesting Engineering.
The design is based on the concept of dynamic isotropy—a mathematical model that defines a system’s ability to move equally effectively in all directions.
The research team simulated over 1,500 design variations to arrive at the most efficient configuration. The result is a robot with 20 modular legs arranged around a central body.
Key design features
- 20 telescopic legs with depth cameras
- arranged according to the geometry of a regular dodecahedron
- no "front" or "back"
- even distribution of load and field of view
This allows the robot to move forward, backward, and sideways equally effectively without turning.
During testing, Argus moved across sand, grass, forest trails, concrete, and wet surfaces, cleared obstacles up to 12.7 cm high, remained stable after impacts, and continued operating even after three legs were damaged.
The robot is also capable of carrying loads up to 4.5 kg, climbing vertical surfaces, and pushing and maneuvering large objects while moving
Researchers note that most modern robots have a dynamic isotropy index below 0.6, whereas Argus’s index reaches 0.91, approaching the theoretical limit.
According to project leader Boyuan Chen, the team aims to create robots that not only follow commands but also help explore the surrounding world in new ways.
