Antagonist Concepts of Polypyrrole Actuators: Bending Hybrid Actuator and Mirrored Trilayer Linear Actuator. [PDF]
Polymers (Basel), 2021 Following the natural muscle antagonist actuation principle, different adaptations for “artificial muscles” are introduced in this work. Polypyrrole (PPy) films of different polymerization techniques (potentiostatic and galvanostatic) were analyzed and their established responses were combined in several ways, resulting in beneficial actuation modes.

A Small-Scale Hopper Design Using a Power Spring-Based Linear Actuator. [PDF]
Biomimetics (Basel), 2023 Hopping locomotion has the potential to enable small-scale robots to maneuver lands quickly while overcoming obstacles bigger than themselves. To make this possible, in this paper, we propose a novel design of a high-power linear actuator for a small ...

Linear pneumatic actuator [PDF]
MATEC Web of Conferences, 2017 The paper presents a linear pneumatic actuator with short working stroke. It consists of a pneumatic motor (a simple stroke cylinder or a membrane chamber), two 2/2 pneumatic distributors “all or nothing” electrically commanded for controlling the intake/outtake flow to/from the active chamber of the motor, a position transducer and a microcontroller ...
