So-called robot–object Lagrangian systems consist of a class of nonsmooth underactuated
complementarity Lagrangian systems, with a specific structure: an “object” and a “robot” …

Considering the anatomy of small intestine involving lesions, circular folds and tumours are
the major sources resisting the locomotion of capsule robots. By mimicking the small-bowel …

This study presents modelling and analysis of a new magneto-mechanical (MM) oscillator
(Wiercigroch et al., 2020), which pays a special attention to mechanical and magnetic …

This paper proposes an arbitrary Lagrange Euler (ALE) method for dynamic modeling and
simulation of cable-driven mechanisms considering stick–slip frictions. The dynamic …

Circular fold is one of the biggest barriers for resisting endoscopic robots moving in the small
intestine. Overcoming such a resistance force for progression during endoscopic procedure …

The vibration-driven locomotion system subject to the Coulomb dry friction is a typical multi-
degree-of-freedom piecewise-smooth dynamical system with rigid-body displacement …

The paper is aimed at studying the motion conditions of the vibratory compacting machine
equipped with the crank excitation mechanism characterized by the changeable geometrical …

The three-dimensional map** of the capsule system with bilateral elastic constraints is
studied, which is rarely seen in the literature at present. The bilaterally constrained elastic …

In this paper, we consider the grazing–sliding bifurcations in a dry-friction oscillator on a
moving belt under periodic excitation. The system is a nonlinear piecewise smooth system …

This paper aims to study the near-grazing bifurcations in a single-degree-of-freedom impact
oscillator with two-side elastic constraints, and further stabilize the near-grazing dynamics …
