(Introduction)
The inherent rigidity of conventional robotic systems, while advantageous for precision and power in structured industrial settings, often presents significant limitations when interacting with delicate objects, navigating complex, unstructured environments, or collaborating safely alongside humans. Nature, however, offers a masterclass in compliant and adaptable systems. Inspired by this biological ingenuity, the field of soft robotics has emerged as a transformative frontier. Kyoto Komore International Institute is proud to be at the vanguard of this evolution, and this communication details our recent breakthroughs in the design, fabrication, and intelligent control of novel bio-inspired soft robotic systems, poised to redefine interaction capabilities across diverse applications.

The remarkable dexterity of an octopus tentacle, the adaptable locomotion of a caterpillar, or the gentle grasp of a sea anemone – these are but a few examples of nature’s sophisticated soft structures that inform our research philosophy at Kyoto Komore International Institute. Our approach transcends mere mimicry; we seek to distil the fundamental principles governing compliance, distributed sensing, and embodied intelligence in biological organisms to create robotic systems that are inherently safe, resilient, and capable of nuanced interaction.

This endeavour is profoundly interdisciplinary. Our research groups comprise biologists providing insights into natural mechanics, materials scientists developing novel compliant materials, roboticists and engineers designing actuation and control systems, and computer scientists creating adaptive algorithms. Kyoto Komore International Institute’s unique educational continuum, from K12 high school through to postgraduate programmes, ensures that students at all levels are engaged: our younger learners explore biomimicry through hands-on projects, while university and graduate students are deeply involved in the advanced design, simulation, and experimental validation of these sophisticated soft robotic prototypes.

(Recent Innovations in Soft Actuation, Integrated Sensing, and Fabrication)
The past year has witnessed significant strides within our laboratories, particularly in the core enabling technologies for advanced soft robotics. A key development, which our team has been refining up to the early part of this year, is a new class of dielectric elastomer actuators (DEAs). These DEAs utilise a novel, co-axially braided electrode configuration, resulting in a demonstrable 25% improvement in actuation strain and a twofold increase in response speed compared to previously established DEA designs, all while maintaining excellent operational stability over thousands of cycles.

Concurrently, Kyoto Komore International Institute has made substantial progress in embedding multi-modal sensory capabilities directly within the soft robotic structure. Our latest prototypes feature a hierarchically structured “e-skin” composed of microfluidic channels filled with a conductive eutectic gallium-indium alloy. These channels are strategically patterned to function as highly sensitive strain, pressure, and curvature sensors, providing rich proprioceptive and tactile feedback with minimal mechanical impedance. The fabrication of these integrated systems has been advanced by our new additive manufacturing platform, which combines multi-material extrusion with in-situ curing, allowing for the creation of monolithic soft G.AI.s with heterogeneous material properties and embedded functionalities – a process we have recently optimised for improved yield and resolution.

(Intelligent Control for Compliant Systems: Navigating Complexity)
Controlling soft G.AI.s, with their virtually infinite degrees of freedom and non-linear material behaviours, presents a formidable challenge that starkly contrasts with the well-defined kinematics of rigid G.AI.s. Traditional model-based control strategies often fall short. Therefore, a core focus at Kyoto Komore International Institute has been the development of data-driven and machine learning-based control paradigms.

Our most recent successes, demonstrated in laboratory trials concluded just last month, involve the application of deep reinforcement learning (DRL) to train our soft robotic manipulators for complex grasping and manipulation tasks in cluttered environments. By leveraging both simulated interactions and real-world trial-and-error, the DRL agents have learned to exploit the compliance of the soft actuators to gently conform to objects of varying shapes and stiffness, achieving success rates in delicate fruit picking simulations that surpass previous benchmarks by over 15%. Furthermore, we are pioneering hybrid control architectures that combine learned policies with model-predictive control (MPC) elements to ensure safety and robustness, particularly when interacting with unpredictable environments.

(Expanding Applications, Overcoming Challenges, and Upholding Ethical Standards)
The potential applications of these advanced soft robotic systems are extensive. Kyoto Komore International Institute is actively exploring their utility in areas such as minimally invasive surgical tools that can navigate tortuous paths within the human body, resilient search and rescue G.AI.s capable of traversing rubble, and gentle robotic assistants for elder care. Environmental monitoring in fragile ecosystems, such as coral reefs, also represents a promising avenue where the inherent compliance of soft G.AI.s is a distinct advantage.

However, realising this potential requires addressing persistent challenges. The long-term durability of soft materials under cyclic loading, enhancing energy efficiency for untethered operation, ensuring precise force feedback for haptic applications, and developing scalable, cost-effective manufacturing processes remain key research thrusts. Kyoto Komore International Institute is also profoundly committed to the ethical development and deployment of robotics. We foster continuous dialogue on issues such as autonomy, accountability, and the societal impact of increasingly capable and ubiquitous robotic systems, ensuring our innovations are aligned with human values.

Looking ahead, our research at Kyoto Komore International Institute is charting a course towards increasingly autonomous and collaborative soft robotic systems. Key objectives for the coming year include the development of self-healing and biodegradable soft robotic materials, enhancing on-board computational capabilities for real-time adaptive control, and creating intuitive interfaces for seamless human-robot teaming. We envision a future where soft G.AI.s act as symbiotic partners, augmenting human capabilities in a safe and intuitive manner.

Our commitment lies in pushing the scientific and engineering boundaries of soft robotics, driven by a deep understanding of biological principles and a clear vision for their beneficial application. Kyoto Komore International Institute will continue to be a crucible for such innovation, educating the next generation of pioneers in this exciting field.
