Prismatic Series of Elastic Actuator: Modelling and Control by ICA and PSO-tuned Fractional Order PID [PDF]

International Journal of Advanced Design and Manufacturing Technology, 2015
: This paper presents dynamic modelling and control of a linear prismatic series of elastic actuator. The capability of generating large torques is why this actuator is increasingly used in human-assistive robotic systems. Due to having human in the loop,

Numerical simulations of a traveling plane-wave actuator for microfluidic applications [PDF]

, 2006
Continuous forming and propagation of large planar deformations on a thin solid elastic film can create propulsion when the film is immersed in a fluid. Microscopic organisms such as spermatozoa use similar mechanisms to propel themselves.

Bio‐Inspired Molecular Events in Poly(Ionic Liquids)

Advanced Functional Materials, EarlyView.
Originating from dipolar and polar inter‐ and intra‐chain interactions of the building blocks, the topologies and morphologies of poly(ionic liquids) (PIL) govern their nano‐ and micro‐processibility. Modulating the interactions of cation‐anion pairs with aliphatic dipolar components enables the tunability of properties, facilitated by “bottom‐up ...

Flexible Joints of Picking Manipulator Based on Current Feedback

IEEE Access, 2020
During the process of automatic picking, malfunctions caused by collisions between the picking manipulator and obstacles can damage plants and/or injure staff. To solve this problem, a flexible joint based on an elastic actuator is designed.

Actuating and Sensing Composites of Liquid Crystal Elastomers and Poly(ionic liquid)s

Advanced Functional Materials, EarlyView.
Ionic conductive, mechanically tough, flexible, and stretchable filaments of a composite material comprising a liquid crystal elastomer and a poly(ionic liquid) are produced through 3D printing, which exhibit large actuation strain under stimulation and electrical resistance variation in response to deformation or environmental condition changes. Their

A nonlinear theory for fibre-reinforced magneto-elastic rods

, 2017
We derive a model for the finite motion of a magneto-elastic rod reinforced with isotropic (spherical) or anisotropic (ellipsoidal) inclusions. The particles are assumed weakly and uniformly magnetised, rigid and firmly embedded into the elastomeric ...
