Soft Robots


We are developing soft robots using dielectric elastomer actuators and fluidic elastomer actuators.


Rapid fabrication method for soft devices using off-the-shelf conductive and dielectric acrylic elastomers


Rapid fabrication is effective for the quick design and fabrication of soft devices. In this study, we have demonstrated a method to rapidly fabricate soft devices by laser processing of ready-made conductive and dielectric materials. With this method, soft robotic elements such as dielectric elastomer actuators, stretchable sensors, and soft pumps can be fabricated within 15-30 min. The wearable device shown on the right is an example of an application. It is capable of sensing finger motion and presenting haptic information, as well as lifting objects by electro-adhesion.

Fish like underwater robots based on dielectric elastomer actuators (DEAs)


This robot has two DEAs attached both side of a thin silicone body. Alternate actuation of the two DEAs realizes swimming motion that resembles real fish.
