Characterization and Selection of Contractile Actuators for Soft Robotics Operating in the Quasistatic Regime

open access: yesAdvanced Intelligent Systems, EarlyView.
We developed methods to characterize soft contractile actuators using force–displacement measurements in the passive state and the total force in the active state and define the operational range of thermal, electrothermal, and pneumatic muscles. A graphical method enables the selection of an actuator based on the required mechanical force–displacement

Accelerating Musculoskeletal Robotics Through Parametric Design and 3D‐Printed Flexible Structures

open access: yesAdvanced Intelligent Systems, EarlyView.
Parametric design and flexible 3D printing create muscle‐, tendon‐, ligament‐, and cushion‐like robotic elements from a single thermoplastic polyurethane material. Tuning lattice patterns adjusts regional mechanical properties and enables coordinated multijoint motions in a life‐sized musculoskeletal leg under external suspension, with partial body ...

Non-Intrusive Fault Detection in Reciprocating Compressors [PDF]

open access: yes, 2012
This research presents techniques developed for non-intrusive sensing and fault detection in reciprocating compressors driven by induction motors. These procedures are “non-intrusive” because they rely only on voltage and current signals measured on the ...
