Nature-inspired flexible robot centipede uses instability for navigation
Introduction:
Technology has once again taken inspiration from nature with the creation of a multi-legged robot that mimics the movement of centipedes. By studying how centipedes navigate rough terrain, researchers from Osaka University in Japan were able to develop a robot with greater stability and maneuverability. The robot, which consists of six segments, each containing two flexible-legged links, can adapt its shape to its environment, similar to how centipedes can. The researchers found that by controlling the robot’s body-axis flexibility instead of directly steering it, they were able to reduce the computational complexity and energy requirements needed to operate it. This robot has potential applications in search and rescue operations, working in hazardous environments, and even exploring other planets. Check out the video below to see the robot’s impressive maneuverability.

Multi-Legged Robot Inspired by Centipedes Shows Improved Stability and Maneuverability
Scientists at Osaka University in Japan have developed a biomimetic multi-legged robot that mimics the movement of centipedes. Inspired by the flexible bodies and adaptability of centipedes traversing diverse terrains, the researchers aimed to create a robot with improved stability and maneuverability.
The Challenge of Multi-Legged Robots
Creating multi-legged robots that can effectively navigate rough terrain has proven challenging for researchers in the past. One common issue is the mechanical stress on the legs, which can limit the robot’s ability to move when one leg malfunctions. Additionally, controlling a large number of legs requires substantial computational power.
The Design of the Robot
To overcome these challenges, the researchers developed a robotic myriapod with six segments, each containing two legs connected by flexible joints. By increasing joint flexibility, they discovered a phenomenon called “pitchfork bifurcation,” where straight walking becomes unstable. Instead of trying to correct the instability, the researchers embraced it, allowing the robot to walk in a curved pattern, similar to the movement of a centipede.
Advantages of the Robot Design
By not directly steering the robot but controlling its body-axis flexibility, the researchers significantly reduced the computational complexity and energy requirements needed to operate the robot. They found that the robot could navigate a curved path to reach a target, showcasing its improved stability and maneuverability.
Applications for the Robot Myriapod
The researchers envision various applications for their robot myriapod, including search and rescue missions, working in hazardous environments, and exploration of other planets. The robot’s ability to adapt to different terrains and its stability make it well-suited for these scenarios.
Future Tests and Research
In the future, the researchers plan to test their design in more challenging environments, such as rough terrains. This will further demonstrate the capabilities of the robot and its potential for real-world applications.

In conclusion, Osaka University’s research team has developed a multi-legged robot inspired by centipedes, demonstrating improved stability and maneuverability. By mimicking the flexible bodies and adaptability of centipedes, the researchers have created a robot with the potential for various applications in challenging environments. Their design, which allows for curved walking, reduces computational complexity and energy requirements. As the researchers continue their work and test the robot in more demanding terrains, they aim to further enhance its capabilities.
Summary: Nature-inspired flexible robot centipede uses instability for navigation
Researchers from Osaka University in Japan have developed a multi-legged robot inspired by the movement of centipedes. By mimicking the curved, side-to-side motion of these animals, the robot achieves greater stability and maneuverability. Unlike previous attempts at biomimetic robots with multiple legs, this new design utilizes flexible joints and a simpler control mechanism. The robot’s ability to walk in a curved pattern allows it to overcome obstacles and navigate diverse terrains. Potential applications for this robot include search and rescue missions, hazardous environment tasks, and exploration on other planets. The researchers plan to test the robot in more challenging environments in the future.
