Renke Liu is a researcher in applied physics, soft robotics, biomimetic robotic systems, shape memory alloy (SMA) actuation, and multi-material 3D printing at Waseda University. His research focuses on translating the anatomical structure and motion principles of the human hand into compact, compliant, and functional robotic systems. In particular, he works on highly biomimetic robotic fingers that integrate tendon-driven mechanisms, soft-rigid hybrid structures, and anatomically inspired joint and soft-tissue components. <\/p>\n\n\n\n

Research<\/strong> <\/p>\n\n\n\n

His research investigates SMA tendon-driven robotic fingers as a compact and muscle-like actuation approach for human-like finger motion. By combining SMA tendon actuation, agonistic\u2013antagonistic mechanisms, cooling-enhanced thermal management, and feedback control, his work aims to realize stable and responsive robotic finger motion within a lightweight, compliant, and human-sized structure. <\/p>\n\n\n\n

Beyond actuation, his research emphasizes anatomical fidelity. Key structures of the human finger, including bones, cartilage, ligaments, palmar plates, tendon sheaths, pulley systems, and the extensor hood mechanism, are incorporated into robotic finger designs to reproduce not only motion but also the underlying biomechanical organization of the human finger. Recent work further explores monolithic multi-material FDM fabrication, in which rigid skeletal elements and compliant soft-tissue-like structures are integrated in a single printing process. <\/p>\n\n\n\n

Research Interests<\/strong> <\/p>\n\n\n\n

His research interests include soft robotics, biomimetic systems, SMA artificial muscles, tendon-driven robotic hands, multi-material additive manufacturing, humanoid robotics, and human\u2013robot interaction. His long-term research goal is to develop anatomically grounded robotic hand and body systems that combine structural biomimicry, compact actuation, and intelligent control for adaptive manipulation in human-centered environments. <\/p>\n\n\n\n

The human finger is a complex musculoskeletal system in which bones, joints, tendons, ligaments, palmar plates, tendon sheaths, and pulley mechanisms work together to achieve dexterity, compliance, and passive stability. In contrast, many conventional robotic hands reproduce finger motion using rigid links, motors, gears, or simplified tendon mechanisms, often without fully reflecting the anatomical organization and biomechanical characteristics of the human finger. <\/p>\n\n\n\n

Our research focuses on the development of highly biomimetic robotic fingers driven by shape memory alloy (SMA) tendon actuation. SMA wires are used as compact, muscle-like artificial tendons, enabling tendon-driven joint motion within a lightweight and human-sized structure. By combining SMA tendon-driven joints, agonistic\u2013antagonistic actuation, cooling-enhanced thermal management, and feedback control, this research aims to realize human-like finger motion in a compact and compliant robotic system. <\/p>\n\n\n\n

In addition to actuation, the research emphasizes anatomical fidelity. Key structures of the human finger, including cartilage, ligaments, palmar plates, tendon sheaths, pulley systems, and the extensor hood mechanism, are incorporated into soft-rigid hybrid robotic fingers. Recent work further explores monolithic multi-material FDM fabrication, where rigid skeletal structures and compliant soft-tissue-like components are integrated in a single printing process. This approach aims to improve anatomical consistency, repeatability, and manufacturability for future biomimetic robotic hands, prosthetic devices, and human\u2013robot interaction systems. <\/p>\n\n\n\n

About this research group <\/strong> <\/p>\n\n\n\n

The Highly Biomimetic Finger Research Group is centered on Liu\u2019s HF3M Finger project, which explores highly biomimetic robotic fingers through SMA tendon actuation, anatomical structural design, and multi-material 3D printing. Within this group, students conduct bachelor\u2019s and master\u2019s thesis research on related topics, including robotic design, actuator development, fabrication methods, sensing, CV tracking and control. <\/p>\n\n\n\n

The group also welcomes part-time researchers and collaborators who wish to contribute to shared research activities. Through collaborative work, the group aims to develop anatomically grounded robotic fingers and to advance practical technologies for future robotic hands, prosthetic devices, and human\u2013robot interaction systems. <\/p>\n\n\n\n
