Researchers have developed a scorpion-inspired sensing system that autonomously adjusts its parameters to perceive dynamic vibrations across variable environments. The Bioinspired Adaptive Tunable Sensing System, or BATSS, draws design principles from the biological closed loop scorpions use to maintain optimal detection states when encountering variable vibration stimuli.
In embodied intelligence, systems require adaptive vibration perception that dynamically responds to target stimuli. Conventional sensing paradigms rely on fixed parameters, which fundamentally limit embodied intelligence from processing wide-range and unpredictable signals in unstructured settings.
To address this limitation, the BATSS architecture autonomously switches among three sensing states featuring distinct parameter configurations based on real-time signal variations. In performance evaluations, the system demonstrated a tunable gauge factor ranging from 17,889 to 29,558, a strain range spanning 0.012% to 2.83%, and precise discrimination of vibration amplitudes across a 500-fold dynamic range between 0.04 and 20 g.
When integrated into a hexapod robot navigating complex terrains, the sensing system enabled adaptive modulation of gait and posture. During testing, the robot achieved a 100% traversal success rate alongside a 34.6% reduction in traversal time, demonstrating potential for robotic applications where autonomy, robustness, and adaptability are required.
The core challenge addressed by the research lies in the limitations of conventional sensing paradigms when applied to embodied intelligence. Standard robotic sensors typically operate with fixed parameter configurations, which inherently restrict their ability to perceive and respond to signals that vary unpredictably across broad operational ranges. In unstructured real-world environments, embodied systems require dynamic perceptual capabilities that continuously adjust to shifting target stimuli. Natural scorpions overcome this sensory bottleneck by relying on a biological closed loop, an architecture that dynamically tunes vibration perception to sustain an optimal detection state regardless of fluctuations in incoming mechanical signals.
To replicate this biological mechanism, the Bioinspired Adaptive Tunable Sensing System incorporates autonomous state-switching behavior. Rather than remaining locked into a single operating mode, the sensor transitions among three distinct sensing states according to real-time variations in external signals. Each of these three states provides a dedicated parameter configuration, enabling the device to reconcile high sensitivity with wide operational margins. Across its configurable states, the system achieves an ultrahigh, tunable gauge factor ranging from 17,889 to 29,558 alongside an operational strain range between 0.012 percent and 2.83 percent. Furthermore, the architecture delivers precise discrimination of vibration amplitudes across a 500-fold dynamic range, successfully detecting signals spanning from 0.04 g to 20 g.
The practical utility of this adaptive perceptual framework was demonstrated by integrating the sensing hardware into a legged robotic platform. When equipped on a hexapod robot traversing complex and irregular terrains, the system actively guided real-time modulation of both locomotion gait and physical posture. By continuously tuning sensory responses to the terrain, the robot achieved a 100 percent traversal success rate while reducing total traversal time by 34.6 percent. These findings advance sensory integration in embodied intelligence, indicating significant promise for autonomous machines operating in unpredictable settings where physical adaptability, operational robustness, and perceptual autonomy are critical requirements.
