Soft Origami Module With Piezoelectric Sensors for Multi-Directional Bending

RA-L 2025

In this letter, a novel soft origami module is proposed to detect multi-directional bending. The module is inspired by the deformability and adaptability of the piezoelectric sensor and origami structure. The detection of applied bending was conducted by the deflection of the piezoelectric sensor, w

Whole-Body Stabilization of Wheeled Bipedal Robots via Decoupled Control of Wheels and Legs

IROS 2025

Wheeled-legged robots offer significant mobility advantages, yet their control is complicated by the coupled dynamics of the wheel and leg systems. To address this challenge, we propose a whole-body control framework built upon a decoupled architecture. In this structure, a two-wheeled inverted pend

Design and Analysis of Origami-Based Multimodal Actuator Capable of Linear and Bending Motion

RA-L 2024

In this letter, a novel cable-driven soft origami multimodal actuator is proposed. The proposed actuator comprises multiple origamis based on the Yoshimura pattern. The origami-based actuator performs both linear and bending motion by exploiting the unique folding state of the origami structure usin

Design of an Accordion-Fold-Inspired Soft Electrohydraulic Actuator for Angular Motion

RA-L 2024

Angular motion of soft actuators is important for utilization in robotic systems. In the robots, the angular motion should enable agile movement and a wide range. This study proposes a novel design of a soft electrohydraulic actuator inspired by an accordion with an improved angular deformation rang
