Propulsion-Based Soft Robotic Actuation
The use of air propulsion to drive limb motion in soft robotics has been a largely untapped field even though the technology has been around since the 1700s. Air propulsion can generate greater degrees of motion in limb actuators compared to widely-experimented pneumatic actuators operating on expandable air channels, which are limited by air pressure input, minimum size and cyclic fatigue. To ...
متن کاملRecent Advances in Smart-material Rotor Control Actuation
This paper reviews recent achievements in the application of active-materials actuation to counteract aeroelastic and vibration effects in helicopters and fixed wing aircraft. A brief review of the induced-strain actuation principles and capabilities is done first. Attention is focused on the smart rotor-blade applications. The induced twist, active blade tip, and active blade flap concepts are...
متن کاملSoft Actuation of Structured Cylinders through Auxetic Behavior
There has been a recent upsurge in the study of auxetic, or negative Poisson’s ratio, materials that derive functionality from mechanical instabilities of the underlying structure. One of the simplest auxetic designs comprises an elastomeric slab patterned with an array of voids. Under uniaxial compression, the slender ligaments contiguous to the voids buckle cooperatively, resulting in the shr...
متن کاملBioinspired Soft Actuation System Using Shape Memory Alloys
Soft robotics requires technologies that are capable of generating forces even though the bodies are composed of very light, flexible and soft elements. A soft actuation mechanism was developed in this work, taking inspiration from the arm of the Octopus vulgaris, specifically from the muscular hydrostat which represents its constitutive muscular structure. On the basis of the authors’ previous...
متن کاملA bioinspired soft actuated material.
A class of soft actuated materials that can achieve lifelike motion is presented. By embedding pneumatic actuators in a soft material inspired by a biological muscle fibril architecture, and developing a simple finite element simulation of the same, tunable biomimetic motion can be achieved with fully soft structures, exemplified here by an active left ventricle simulator.
