Artificial Neural Network-Aided Computational Approach for Mechanophenotyping of Biological Cells Using Atomic Force Microscopy.
Journal of biomechanical engineering
Jul 1, 2023
The artificial neural network (ANN) based models have shown the potential to provide alternate data-driven solutions in disease diagnostics, cell sorting and overcoming AFM-related limitations. Hertzian model-based prediction of mechanical properties...
Soft robotic steerable microcatheter for the endovascular treatment of cerebral disorders.
Science robotics
Aug 18, 2021
Catheters used for endovascular navigation in interventional procedures lack dexterity at the distal tip. Neurointerventionists, in particular, encounter challenges in up to 25% of aneurysm cases largely due to the inability to steer and navigate the...
Programmable and reprocessable multifunctional elastomeric sheets for soft origami robots.
Science robotics
Apr 7, 2021
Tunable, soft, and multifunctional robots are contributing to developments in medical and rehabilitative robotics, human-machine interaction, and intelligent home technology. A key aspect of soft robot fabrication is the ability to use flexible and e...
Autonomous Control of a Tendon-driven Robotic Limb with Elastic Elements Reveals that Added Elasticity can Enhance Learning.
Annual International Conference of the IEEE Engineering in Medicine and Biology Society. IEEE Engineering in Medicine and Biology Society. Annual International Conference
Jul 1, 2020
Passive elastic elements can contribute to stability, energetic efficiency, and impact absorption in both biological and robotic systems. They also add dynamical complexity which makes them more challenging to model and control. The impact of this ad...
Analysis on an Origami-structured Actuator that Enhances Both Backdriveability and Power Amplification.
IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Jun 1, 2019
In the author's previous study, an origami-structured compliant actuator, named OSCA, was invented for human-robot interaction where sufficient moment output is required under a limited power supply. In this study, the compressibility of airflow with...
Robust Optimal Design of Energy Efficient Series Elastic Actuators: Application to a Powered Prosthetic Ankle.
IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Jun 1, 2019
Design of rehabilitation and physical assistance robots that work safely and efficiently despite uncertain operational conditions remains an important challenge. Current methods for the design of energy efficient series elastic actuators use an optim...
A Model Inversion Procedure for Control of Nonlinear Series Elastic Actuators.
IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Jun 1, 2019
This paper presents a model inversion procedure for a viscoelastic compliant element contained within a rotary series elastic actuator (SEA). Model inversion plays an important role in enabling accurate model-based control of physical human-robot int...
Blind prediction of protein B-factor and flexibility.
The Journal of chemical physics
Oct 7, 2018
The Debye-Waller factor, a measure of X-ray attenuation, can be experimentally observed in protein X-ray crystallography. Previous theoretical models have made strong inroads in the analysis of beta (B)-factors by linearly fitting protein B-factors f...
Estimating mechanical properties of cloth from videos using dense motion trajectories: Human psychophysics and machine learning.
Journal of vision
May 1, 2018
Humans can visually estimate the mechanical properties of deformable objects (e.g., cloth stiffness). While much of the recent work on material perception has focused on static image cues (e.g., textures and shape), little is known about whether huma...
An integrated design and fabrication strategy for entirely soft, autonomous robots.
Nature
Aug 25, 2016
Soft robots possess many attributes that are difficult, if not impossible, to achieve with conventional robots composed of rigid materials. Yet, despite recent advances, soft robots must still be tethered to hard robotic control systems and power sou...
