Core Concepts
phloSAR enables untethered operation of large pneumatic soft robots with high-flow requirements.
Abstract
Pneumatic actuation benefits soft robotics by facilitating compliance and large volume change.
Existing portable pneumatic systems are limited in dynamic capabilities.
PhloSAR proposes a high-flow pressure supply and regulator for untethered, weight-constrained soft robot applications.
The system leverages high-flow proportional valves, an integrated pressure reservoir, and Venturi vacuum generation.
Models describe system dynamics and experimental validation on physical hardware.
Integration with a soft robot arm mounted on an aerial vehicle demonstrates portability and applicability to mobile robotics.
Design considerations include form, dynamic performance, and untethered operation.
PhloSAR balances performance, operation duration, and design parameters for system operation.
Experimental verification of system dynamics and frequency response.
