A Symmetric Bidirectional Soft Rotary Actuator with a Bendable Shaft Driven by Extension-Type Pneumatic Actuators
Highlights A soft rotary actuator (SB-SRA) achieves bidirectional rotational motion by arranging extension-type flexible pneumatic actuators in an opposed configuration, even when its flexible shaft is bent. The rotation angle and torque are symmetrical in both directions (up to 105° and 0.51 Nm), and static hysteresis...
