Afzal, Naqash (author), du Bois de Dunilac, Sophie (author), Loutit, Alastair J. (author), Shea, Helen O. (author), Ulloa, Pablo Martinez (author), Khamis, Heba (author), Vickery, Richard M. (author), Wiertlewski, M. (author), Redmond, Stephen J. (author), Birznieks, Ingvars (author)Abstract: When manipulating objects, humans begin adjusting their grip force to friction within 100 ms of contact. During motor adaptation, subjects become aware of the slipperiness of touched surfaces. Previously, we have demonstrated that humans cannot perceive frictional differences when surfaces are brought in contact with an immobilised...journal article 2024

Engelen, Anouk (author)During human motor control, sensory information is integrated, and the influence of each cue depends on its variance. Sensory weighting within the proprioceptive system, specifically between force and position feedback, including its stiffness dependency, has been demonstrated for the shoulder and digits. Both studies encompass upper limb joints...master thesis 2023

Saveriano, Matteo (author), Abu-Dakka, Fares J. (author), Kramberger, Aljaž (author), Peternel, L. (author)Biological systems, including human beings, have the innate ability to perform complex tasks in a versatile and agile manner. Researchers in sensorimotor control have aimed to comprehend and formally define this innate characteristic. The idea, supported by several experimental findings, that biological systems are able to combine and adapt...review 2023

Geelen, J.E. (author), van der Helm, F.C.T. (author), Schouten, A.C. (author), Mugge, W. (author)Human hands are complex biomechanical systems that allow for dexterous tasks with many degrees of freedom. Coordination of the fingers is essential for many activities of daily living and involves integrating sensory signals. During this sensory integration, the central nervous system deals with the uncertainty of sensory signals. When...journal article 2023

Buetler, Karin A. (author), Penalver-Andres, Joaquin (author), Özen, Özhan (author), Ferriroli, Luca (author), Müri, René M. (author), Cazzoli, Dario (author), Marchal Crespo, L. (author)To offer engaging neurorehabilitation training to neurologic patients, motor tasks are often visualized in virtual reality (VR). Recently introduced head-mounted displays (HMDs) allow to realistically mimic the body of the user from a first-person perspective (i.e., avatar) in a highly immersive VR environment. In this immersive environment,...journal article 2022

Özen, Özhan (author), Buetler, Karin A. (author), Marchal Crespo, L. (author)BACKGROUND: Current robot-aided training allows for high-intensity training but might hamper the transfer of learned skills to real daily tasks. Many of these tasks, e.g., carrying a cup of coffee, require manipulating objects with complex dynamics. Thus, the absence of somatosensory information regarding the interaction with virtual objects...journal article 2022

Staps, Sam (author)Conventional steering systems in passenger vehicles have a mechanically fixed steering ratio. The steering sensitivity, defined as the amount of vehicle response to the driver's steering wheel input, remains fixed with changing road environments. Research has shown that driving comfort and safety can be improved when the vehicle's steering...master thesis 2021

van de Ruit, M.L. (author), Mugge, W. (author), Cavallo, Gaia (author), Lataire, John (author), Ludvig, Daniel (author), Schouten, A.C. (author)Accurate and swift tuning of joint impedance is crucial to perform movement and interaction with our environment. Time-varying system identification enables quantification of joint impedance during movement. Many methods have been developed over the years, each with their own mathematical approach and underlying assumptions. Yet, for the...journal article 2021

Averta, Giuseppe (author), Arapi, Visar (author), Bicchi, Antonio (author), Della Santina, C. (author), Bianchi, Matteo (author)The need for users’ safety and technology acceptability has incredibly increased with the deployment of co-bots physically interacting with humans in industrial settings, and for people assistance. A well-studied approach to meet these requirements is to ensure human-like robot motions and interactions. In this manuscript, we present a...book chapter 2021

Angelini, Franco (author), Della Santina, C. (author), Garabini, Manolo (author), Bianchi, Matteo (author), Bicchi, Antonio (author)Human beings can achieve a high level of motor performance that is still unmatched in robotic systems. These capabilities can be ascribed to two main enabling factors: (i) the physical proprieties of human musculoskeletal system, and (ii) the effectiveness of the control operated by the central nervous system. Regarding point (i), the...journal article 2020

del Valle Hidalgo, Alejandro (author)Reflexes and co-contraction are the two mechanisms used for effective limb control when humans face unexpected perturbations in their daily activities. When the environment has reduced stability margins, reflexes are tempered due to the oscillations caused by the neural time delay of the reflexive pathways. An explanation is that reflexes adapt...master thesis 2019

Booth, Adam T.C. (author), van der Krogt, Marjolein M. (author), Harlaar, J. (author), Dominici, Nadia (author), Buizer, Annemieke I. (author)Background: Children with cerebral palsy (CP) often show impaired selective motor control (SMC) that induces limitations in motor function. Children with CP can improve aspects of pathological gait in an immediate response to visual biofeedback.

Kraaijevanger, Sven (author)Joint impedance describes the dynamic resistance of a joint in response to position perturbations. Joint impedance is known to vary nonlinearly during movement caused by varying joint angle and muscle activation. The nonlinear behaviour can be described using linear time-varying models under certain assumption. Recently a number of time-varying...master thesis 2018
