Estimation of Full-Body Poses Using Only Five Inertial Sensors: An Eager or Lazy Learning Approach?
Sensors (Basel, Switzerland)
Dec 15, 2016
Human movement analysis has become easier with the wide availability of motion capture systems. Inertial sensing has made it possible to capture human motion without external infrastructure, therefore allowing measurements in any environment. As high...
Design and Optimization of a Hybrid-Driven Waist Rehabilitation Robot.
Sensors (Basel, Switzerland)
Dec 14, 2016
In this paper a waist rehabilitation robot driven by cables and pneumatic artificial muscles (PAMs) has been conceptualized and designed. In the process of mechanism design, the human body structure, the waist movement characteristics, and the actuat...
Robot-guided ankle sensorimotor rehabilitation of patients with multiple sclerosis.
Multiple sclerosis and related disorders
Dec 12, 2016
BACKGROUND: People with multiple sclerosis (MS) often develop symptoms including muscle weakness, spasticity, imbalance, and sensory loss in the lower limbs, especially at the ankle, which result in impaired balance and locomotion and increased risk ...
Approximate analytical solutions to the double-stance dynamics of the lossy spring-loaded inverted pendulum.
Bioinspiration & biomimetics
Dec 5, 2016
This paper introduces approximate time-domain solutions to the otherwise non-integrable double-stance dynamics of the 'bipedal' spring-loaded inverted pendulum (B-SLIP) in the presence of non-negligible damping. We first introduce an auxiliary system...
Exoskeleton plantarflexion assistance for elderly.
Gait & posture
Nov 28, 2016
Elderly are confronted with reduced physical capabilities and increased metabolic energy cost of walking. Exoskeletons that assist walking have the potential to restore walking capacity by reducing the metabolic cost of walking. However, it is unclea...
An information-based machine learning approach to elasticity imaging.
Biomechanics and modeling in mechanobiology
Nov 18, 2016
An information-based technique is described for applications in mechanical property imaging of soft biological media under quasi-static loads. We adapted the Autoprogressive method that was originally developed for civil engineering applications for ...
Biomechanical advantages of robot-assisted pedicle screw fixation in posterior lumbar interbody fusion compared with freehand technique in a prospective randomized controlled trial-perspective for patient-specific finite element analysis.
The spine journal : official journal of the North American Spine Society
Nov 17, 2016
BACKGROUND CONTEXT: There have been conflicting results on the surgical outcome of lumbar fusion surgery using two different techniques: robot-assisted pedicle screw fixation and conventional freehand technique. In addition, there have been no studie...
Robotic vertical jumping agility via series-elastic power modulation.
Science robotics
Nov 16, 2016
Several arboreal mammals have the ability to rapidly and repeatedly jump vertical distances of 2 m, starting from rest. We characterize this performance by a metric we call vertical jumping agility. Through basic kinetic relations, we show that this ...
Locomotor training through a novel robotic platform for gait rehabilitation in pediatric population: short report.
Journal of neuroengineering and rehabilitation
Nov 14, 2016
BACKGROUND: Cerebral Palsy (CP) is a disorder of posture and movement due to a defect in the immature brain. The use of robotic devices as alternative treatment to improve the gait function in patients with CP has increased. Nevertheless, current gai...
A Novel Robot System Integrating Biological and Mechanical Intelligence Based on Dissociated Neural Network-Controlled Closed-Loop Environment.
PloS one
Nov 2, 2016
We propose the architecture of a novel robot system merging biological and artificial intelligence based on a neural controller connected to an external agent. We initially built a framework that connected the dissociated neural network to a mobile r...
