Elastic Inflatable Actuators for Soft Robotic Applications [PDF]

open access: yesAdvanced Materials, 2017
AbstractThe 20th century's robotic systems have been made from stiff materials, and much of the developments have pursued ever more accurate and dynamic robots, which thrive in industrial automation, and will probably continue to do so for decades to come. However, the 21st century's robotic legacy may very well become that of soft robots.

Helical beating of an actuated elastic filament [PDF]

open access: yesJournal of Physics: Condensed Matter, 2009
We investigate the propulsive force resulting from the rotation of a flexible filament in the low Reynolds number regime. Using a simple linear model, we establish the nonlinear torque-force relations for two torque-driven actuation modes. When the rotation of the filament is induced by two perpendicular transverse oscillating torques, the propulsive ...
