Learning Augmented Joint-Space Task-Oriented Dynamical Systems:A Linear Parameter Varying and Synergetic Control Approach

Aude Billard, Nadia Barbara Figueroa Fernandez, Seyed Sina Mirrazavi Salehian, Yonadav Goldwasser Shavit

In this paper, we propose an asymptotically stable joint-space dynamical system that captures desired behaviors in joint-space while stably converging towards a task-space attractor. To encode joint-space behaviors while meeting the stability criteria, the ...

A Robotic System for Adaptive Training and Function Assessment of Forelimb Retraction in Mice

Silvestro Micera, Stefano Lai, Maria Pasquini, Sara Conti

Rodent models are decisive for translational research in healthy and pathological conditions of motor function thanks to specific similarities with humans. Here, we present an upgraded version of the M-Platform, a robotic device previously designed to trai ...

On the theory of variance reduction for stochastic gradient monte carlo

Nicolas Henri Bernard Flammarion

We show that accelerated gradient descent, averaged gradient descent and the heavy-ball method for quadratic non-strongly-convex problems may be reformulated as constant parameter secondorder difference equation algorithms, where stability of the system is ...

Stiffness variability in jamming of compliant granules and a case study application in climbing vertical shafts

Auke Ijspeert, Mehmet Hasan Mutlu, Simon Lukas Hauser, Frédéric Freundler

Jamming of granular media has been shown to possess the property of stiffness variation, transitioning from a soft to a quasi-solid state depending on the packing density of the granules. Recently, a gradual stiffness change for bending has been reported b ...

Dynamic causal modelling of EEG and fMRI to characterize network architectures in a simple motor task

Friedhelm Christoph Hummel

Dynamic causal modelling (DCM) has extended the understanding of brain network dynamics in a variety of functional systems. In the motor system, DCM studies based on functional magnetic resonance imaging (fMRI) or on magneto-/electroencephalography (M/EEG) ...

Engagement of the Rat Hindlimb Motor Cortex across Natural Locomotor Behaviors

Silvestro Micera, Grégoire Courtine, Rubia van den Brand, Jacopo Rigosa, Lucia Florinda Friedli Wittler, Janine Beauparlant, Simone Ellen Joze Duis, Julie Kreider

Contrary to cats and primates, cortical contribution to hindlimb locomotor movements is not critical in rats. However, the importance of the motor cortex to regain locomotion after neurological disorders in rats suggests that cortical engagement in hindlim ...

Moment-sum-of-squares hierarchies for set approximation and optimal control

Milan Korda

This thesis uses the idea of lifting (or embedding) a nonlinear controlled dynamical system into an infinite-dimensional space of measures where this system is equivalently described by a linear equation. This equation and problems involving it are subsequ ...

Concept of a soft exosuit for the support of leg function in rehabilitation

In the past couple of years, the concept of exosuits has emerged. These soft, robotic devices are primarily made of textiles and can be worn like clothes. They assist the user during specific motions by transmitting forces around the human joints making us ...

Generalization of motor resonance during the observation of hand, mouth, and eye movements

Michela Bassolino

Transcranial magnetic stimulation (TMS) of the motor cortex shows that hand action observation (AO) modulates corticospinal excitability (CSE). CSE modulation alternatively maps low-level kinematic characteristics or higher-level features, like object-dire ...

Disrupting the ipsilateral motor cortex interferes with training of a complex motor task in older adults

Friedhelm Christoph Hummel

Performance of unimanual movements is associated with bihemispheric activity in the motor cortex in old adults. However, the causal functional role of the ipsilateral MC (iMC) for motor control is still not completely known. Here, the behavioral consequenc ...
