Researchers at Osaka University have developed an innovative centipede-inspired robot that can switch between straight and curved walking, revolutionizing the field of robotics. By harnessing dynamic instability, the robot can navigate through challenging terrains without the need for complex computational control systems. The team achieved this by adjusting the flexibility of the robot's couplings, allowing it to smoothly transition from straight to curved walking patterns. [1]

Figure 1 shows a centipede-inspired robot. Traditional legged robots often struggle with fragility and the stress-induced breakdown of individual legs. Moreover, controlling a large number of joints to maneuver complex environments demands significant computational power. Osaka University's biomimetic "myriapod" robot overcomes these limitations by leveraging controlled instability to enable efficient maneuverability. [1]

The robot comprises six segments, with two legs attached to each segment, and features flexible joints. By modifying the couplings' flexibility using adjustable screws and motors, the researchers observed a "pitchfork bifurcation" phenomenon, where straight walking becomes unstable. Instead, the robot seamlessly transitions to curved walking, either to the right or left. This novel approach significantly reduces computational complexity and energy requirements by controlling flexibility instead of directly steering the body axis. [1]

The researchers conducted tests to evaluate the robot's ability to reach specific locations, and it successfully navigated by taking curved paths toward the targets. This breakthrough has wide-ranging implications, particularly in search and rescue operations, hazardous environments, and planetary exploration. The robot's agility and adaptability make it a promising tool for scenarios where quick movement changes and efficient locomotion are crucial. [1]

Osaka University's team envisions future iterations of the robot incorporating additional segments and control mechanisms, further advancing the capabilities of this centipede-like robot. [1]
