空気駆動ロボットを電子機器なしで同期移動させる技術を開発(Researchers develop air-powered robots that move in sync without electronics)

オックスフォード大学の研究チームは、電子回路やモーターを一切使わず、空気圧だけで動くソフトロボットを開発した。各ユニットは、駆動・感覚・気流制御の3機能を兼ね備えるモジュール構造で、複数つなげることで跳ねる、揺れる、這うといった動作を実現する。特に、電子的な制御を持たないにもかかわらず、ユニット同士が地面反力や摩擦を介して自然に同期運動を生み出す点が大きな特徴である。この同期現象はKuramotoモデルで説明され、ロボットの構造そのものが制御を担う「身体性知能」の例として注目される。将来は電子装置不要の自律ロボットへの応用が期待される。

Abstract

Fluidic circuits have shown significant promise in enabling complex functionality in soft robots with a minimal number of input signals. However, implementing complex behaviors typically involves numerous specialized components, resulting in intricate and nonversatile circuits. To address this challenge, a multifunctional fluidic unit designed to operate flexibly as a valve, sensor, or actuator is introduced. This unit provides an extensive design space that allows precise tuning to achieve the desired functionality. In particular, one configuration integrates all three functions simultaneously, resulting in a self-sensing oscillating actuator. By assembling multiple units—each customized for specific roles—complex robotic behaviors can be realized. The versatility and effectiveness of this modular approach are demonstrated by creating several robotic systems, including a controlled shaker, a multimodal hopper, and a crawler capable of sensing environmental boundaries. Furthermore, when these units are mechanically coupled via a shared body, it exhibit emergent passive behaviors, such as self-synchronization—a behavior that is elucidated with a Kuramoto model of networks of oscillators. This study highlights the potential of multifunctionality as a powerful and efficient strategy for realizing embodied intelligence in fluidic robotic systems.
