Should researchers prioritize biological mimicry when designing robots for complex or unpredictable environments?
Researchers from Tohoku University and VISTEC have developed an AI-based walking controller for six-legged robots inspired by insect movement. The system enables the robot to navigate uneven surfaces and reorganize its gait automatically when a leg is disabled.
Why it matters
Predefined walking patterns often fail on unpredictable terrain or when hardware sustains damage. This new technology provides a more flexible approach to robotic locomotion, potentially improving performance in complex environments.
The robot operates with 6 legs and 18 individually controlled joints. It utilizes adversarial inverse reinforcement learning and proximal policy optimization to maintain stability on uneven ground.
The players
Tohoku University
This is a public research university located in Sendai, Japan, that focuses on engineering and scientific innovation.
VISTEC
VISTEC is a graduate-level research institution in Thailand that specializes in science and technology development.
The details
The controller was built using movement data recorded from the stick insect Medauroidea extradentata. By analyzing 18 leg joints during insect movement, the AI determines the underlying reward structure to manage the robot's locomotion dynamically.

The Tech Race
This development represents a departure from traditional programmed locomotion, following the pattern of bio-inspired design seen in the RedMirror robot. It pushes the boundaries of autonomous navigation by replacing rigid software instructions with adaptable machine learning.
Future applications of this technology are expected to support defense, infrastructure inspection, and emergency response. These advancements could eventually lead to more resilient robotic tools capable of operating in disaster zones where human access is limited.
The takeaway
Bio-inspired artificial intelligence is successfully bridging the gap between biological agility and mechanical robustness in robotics. Designers and developers can look toward this method for creating machines that maintain functionality after suffering physical hardware failure.
