Kotian, V. (author), Irmak, T. (author), Pool, D.M. (author), Happee, R. (author)Users of automated vehicles will engage in other activities and take their eyes off the road, making them prone to motion sickness. To resolve this, the current paper validates models predicting sickness in response to motion and visual conditions. We validate published models of vestibular and visual sensory integration that have been used...journal article 2024

Caradonna, Daniele (author), Pierallini, M. (author), Della Santina, C. (author), Angelini, Franco (author), Bicchi, Antonio (author)Soft robots enable safe and robust operations in unstructured environments. However, the nonlinearities of their continuum structure complicate the accomplishment of classic robotic tasks, such as pick and place. In this work, we propose the R-Soft Inverted Pendulum, a Soft Inverted Pendulum (SIP) actuated only by a revolute joint at the base...journal article 2024

Coppola, R. (author), Peruffo, A. (author), Mazo, M. (author)We introduce a novel approach for the construction of symbolic abstractions - simpler, finite-state models - which mimic the behaviour of a system of interest, and are commonly utilized to verify complex logic specifications. Such abstractions require an exhaustive knowledge of the concrete model, which can be difficult to obtain in real...journal article 2023

Field Model Identification and Control of a Mobile Electromagnet for Remote Actuation of Soft RobotsRiccardi, A. (author), Furtado, Guilherme P. (author), Sikorski, Jakub (author), Vendittelli, Marilena (author), Misra, Sarthak (author)The actuation of miniaturized robots through external magnetic fields has great potential for medical applications. The controllability properties of the miniaturized robots are affected by magnetic field generation modality. In this work, the magnetic field of a mobile electromagnet, notably capable to generate a desired magnetic field in...journal article 2023

Rizki, Z. (author), Ravesloot, Richard (author), van Beckhoven, Ruud (author), Ottens, M. (author)The ultrafiltration/diafiltration (UF/DF) process is a crucial step in the canola protein isolation process from rapeseed meal. The process involves using a multi-stage membrane system to separate components of the mixture. As diafiltration dilutes the feed stream in the ultrafiltration system, a large amount of diafiltration water is...journal article 2023

Bjelonic, Filip (author), Sachtler, Arne (author), Albu-Schaffer, Alin (author), Della Santina, C. (author)Adding elastic elements to the mechanical structure should enable robots to perform efficient oscillatory tasks. Still, even characterizing natural oscillations in nonlinear systems is a challenge in itself, which nonlinear modal theory promises to solve. Therein eigenmanifolds generalize eigenspaces to mechanical systems with non-Euclidean...journal article 2022

Lasisi, S.O. (author), Benson, T.M. (author), Greenaway, M.T. (author), Gradoni, G. (author), Cools, K. (author)We demonstrate how the coupling of a full-wave time-domain boundary element method (BEM) solver with a circuit solver can be used to model 1) the generation of high frequency oscillations in resonant tunneling diode (RTD) oscillators, and 2) the mutual coupling and synchronization of non-identical RTDs with significant differences in frequencies...journal article 2022

Tacx, Paul (author), Oomen, T.A.E. (author)Next-generation motion stages are envisaged to be lightweight to meet stringent demands regarding accuracy and throughput. The lightweight stage design implies flexible dynamical behavior, which is foreseen to be severely excited due to increasing acceleration forces. The aim of this paper is to exploit additional actuators and sensors to...journal article 2022

Aydin, B.B. (author), Binici, Baris (author), Hendriks, M.A.N. (author), Tuncay, Kagan (author)Significant infill wall damage in reinforced concrete frame buildings was observed in the past earthquakes. A vast number of numerical approaches have been proposed to estimate the non-linear behavior of infilled frames at different scales. Mesoscale lattice models were successfully used in the past to simulate the behavior of reinforced...journal article 2022

Pustina, P. (author), Della Santina, C. (author), De Luca, Alessandro (author)The intrinsically underactuated and nonlinear nature of continuum soft robots makes the derivation of provably stable feedback control laws a challenging task. Most of the works so far circumvented the issue either by looking at coarse fully-actuated approximations of the dynamics or by imposing quasi-static assumptions. In this letter, we...journal article 2022

Nadimi, Navid (author), Sangdeh, Amin Khoshdel (author), Berangi, M.J.B. (author)This paper intends to assess the effect of different parameters on traffic congestion around universities. On the basis of the model outputs, it is possible to propose economic countermeasures for reducing traffic congestion, especially in developing countries. Structural equation modelling was used to assess the relevance between...journal article 2022
