Macro-Mini Linear Actuator Using Electrorheological-Fluid Brake for Impedance Modulation in Physical Human-Robot Interaction

RA-L 2022

Robots designed to interact physically with humans are typically characterized by low impedance and low output force, but in many circumstances, high force is needed. Integrated to a high-torque velocity source, antagonistic designs of electrorheological (ER)-fluid or magnetorheological (MR)-fluid c

Design and Modeling of a Variable-Stiffness Spring Mechanism for Impedance Modulation in Physical Human–Robot Interaction

ICRA 2021poster

Our goal is to investigate different approaches to modulate stiffness and apply them to human-robot interaction. Here we report on our effort employing the concept of adjustable unsupported-length cantilever leaf spring, which has been previously applied to different designs of variable stiffness ac…

A Soft Pneumatic Actuator as a Haptic Wearable Device for Upper Limb Amputees: Toward a Soft Robotic Liner

RA-L 2019

Object manipulation and fluid, goal-directed, movements require sensory information for effective execution. Amputees lose this intrinsic feedback when controlling their artificial limbs and must instead rely on visual information to compensate. Here, we describe an application for providing touch a

Adaptive Impedance Control Applied to Robot-Aided Neuro-Rehabilitation of the Ankle

RA-L 2019

Robot-aided neuro-rehabilitation is a potential solution to help resolve the increasing demand for post-stroke therapy. In this letter, we propose an assistive-resistive approach to promote active patient participation during robotic therapy. In order to automatically determine the most appropriate

Robotics for Sugarcane Cultivation: Analysis of Billet Quality using Computer Vision

RA-L 2018

In much of the world, sugarcane is planted in a mechanized fashion using billets, which are shorter segments of cane harvested and cut by a combine harvester. The mechanized harvesting process can damage billets, which introduces pathways for disease, and overall reduction of billet quality. Compare
