Universal Soft Robotic Microgripper [PDF]

open access: yesSmall, 2018
AbstractHere, a soft robotic microgripper is presented that consists of a smart actuated microgel connected to a spatially photopatterned multifunctional base. When pressed onto a target object, the microgel component conforms to its shape, thus providing a simple and adaptive solution for versatile micromanipulation. Without the need for active visual

Self-Sensing Control for Soft-Material Actuators Based on Dielectric Elastomers [PDF]

open access: yes, 2019
Due to their energy density and softness that are comparable to human muscles dielectric elastomer (DE) transducers are well-suited for soft-robotic applications. This kind of transducer combines actuator and sensor functionality within one transducer so

Port-Hamiltonian modeling for soft-finger manipulation [PDF]

open access: yes, 2010
In this paper, we present a port-Hamiltonian model of a multi-fingered robotic hand, with soft-pads, while grasping and manipulating an object. The algebraic constraints of the interconnected systems are represented by a geometric object, called Dirac ...

Bubble casting soft robotics

open access: yesNature, 2021
Inspired by living organisms, soft robots are developed from intrinsically compliant materials, enabling continuous motions that mimic animal and vegetal movement1. In soft robots, the canonical hinges and bolts are replaced by elastomers assembled into actuators programmed to change shape following the application of stimuli, for example pneumatic ...

Analysis of Compensatory Movements Using a Supernumerary Robotic Hand for Upper Limb Assistance

open access: yesFrontiers in Robotics and AI, 2020
Recently, extratheses, aka Supernumerary Robotic Limbs (SRLs), are emerging as a new trend in the field of assistive and rehabilitation devices. We proposed the SoftHand X, a system composed of an anthropomorphic soft hand extrathesis, with a gravity ...

Monolithic shape-programmable dielectric liquid crystal elastomer actuators

open access: yes, 2019
Macroscale robotic systems have demonstrated great capabilities of high speed, precise, and agile functions. However, the ability of soft robots to perform complex tasks, especially in centimeter and millimeter scale, remains limited due to the ...

Shared Autonomy via Hindsight Optimization [PDF]

open access: yes, 2015
In shared autonomy, user input and robot autonomy are combined to control a robot to achieve a goal. Often, the robot does not know a priori which goal the user wants to achieve, and must both predict the user's intended goal, and assist in achieving ...

Usability Assessment of Body Controlled Electric Hand Prostheses: A Pilot Study

open access: yesFrontiers in Neurorobotics, 2021
Poly-articulated hands, actuated by multiple motors and controlled by surface myoelectric technologies, represent the most advanced aids among commercial prostheses.

Leveraging Elastic instabilities for Amplified Performance: spine-inspired high-speed and high-force soft robots

open access: yes, 2020
Soft machines typically exhibit slow locomotion speed and low manipulation strength because of intrinsic limitations of soft materials. Here, we present a generic design principle that harnesses mechanical instability for a variety of spine-inspired fast

Genetic attenuation of ALDH1A1 increases metastatic potential and aggressiveness in colorectal cancer

open access: yesMolecular Oncology, EarlyView.
Aldehyde dehydrogenase 1A1 (ALDH1A1) is a cancer stem cell marker in several malignancies. We established a novel epithelial cell line from rectal adenocarcinoma with unique overexpression of this enzyme. Genetic attenuation of ALDH1A1 led to increased invasive capacity and metastatic potential, the inhibition of proliferation activity, and ultimately ...
