LED Pouch Motor: Wavelength Selective Wireless Actuation of Dyed Liquid-to-Gas Phase Change Actuators Using LEDs

RA-L 2026

Untethered soft actuators that operate without physical connections to external power sources or control system cables are an active area of research for their potential applications in human-robot interaction, haptic devices, and 4D printing due to their wide range of motion and high degrees of fre

Robot Swarm Control Based on Smoothed Particle Hydrodynamics for Obstacle-Unaware Navigation

IROS 2024poster

Robot swarms hold immense potential for performing complex tasks far beyond the capabilities of individual robots. However, the challenge in unleashing this potential is the robots’ limited sensory capabilities, which hinder their ability to detect and adapt to unknown obstacles in real-time. To ove…

Micro Elastic Pouch Motors: Elastically Deformable and Miniaturized Soft Actuators Using Liquid-to-Gas Phase Change

RA-L 2021

In the present study, we propose a largely deformable and miniaturized soft actuator that is made by an elastic rubber bladder (called a pouch) with a low-boiling-point liquid. When the temperature of the low-boiling-point liquid reaches 34 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:x

Laser Pouch Motors: Selective and Wireless Activation of Soft Actuators by Laser-Powered Liquid-to-Gas Phase Change

RA-L 2020

Untethered control of soft-bodied robots is attractive for interactions in a variety of unstructured and dynamic environments. However, soft robotics systems are currently limited in terms of wireless, selective, and scalable control of multiple actuators. Therefore, we propose a method to wirelessl
