Printable Origami Bistable Structures for Foldable Jumpers

ICRA 2022poster

Origami/kirigami robotics are opening a path that leads to lightweight, compact, and expandable robots. However, it is generally challenging to design agile motions for origami/kirigami robots due to their size and the intrinsic limitation of the materials. In this paper, we propose to use the bista…

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

Liquid Pouch Motors: Printable Planar Actuators Driven by Liquid-to-Gas Phase Change for Shape-Changing Interfaces

RA-L 2020

Conventional planar pneumatic actuators have not been able to make the most of their thin, lightweight, and flexible nature due to tubes and pumps inevitably connected to them. In this article, we build upon our prior work and propose Liquid Pouch Motors, a family of printable soft actuators that co

Electric phase-change actuator with inkjet printed flexible circuit for printable and integrated robot prototyping

ICRA 2017poster

The integrated fabrication of body structures, actuators, sensors, and electronic circuits into one robot system is an open problem in robotics. Simple and rapid construction of electric actuators in the body through existing approaches is difficult. We take advantage of the liquid-to-gas phase chan…
