This paper studies the intestinal frictions acting on a millimetre-scale self-propelled capsule
(26 mm in length and 11 mm in diameter) for small bowel endoscopy by considering …

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 vibro-impact capsule system has been studied extensively in the past decade because
of its research challenges as a piecewise-smooth dynamical system and broad applications …

Discontinuous friction and impact exist in a variety of piecewise-smooth dynamical systems
that exhibit rich and complex nonlinear phenomena. This paper aims to study the …

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

The physics model of isotropically connected and reversely connected dual-unit collision
and stick-slip vibration-driven system (ICVDS, RCVDS) with a wide range of drive speed …

This paper investigates the complex dynamical behavior of a rigid block structure under
harmonic ground excitation, thereby mimicking, for instance, the oscillation of the system …

In this paper, boundary regions of 1-D linear piecewise-smooth discontinuous maps are
examined analytically. It is shown that, under certain parameter conditions, maps exhibit …

为了满足垂直管道检测的需求, 设计了一种带外鳍振动驱动的机器人, 并进行了运动机理研究.
根据机器人的结构, 考虑摩擦和冲击这两个非光滑非线性因素, 建立了机器人系统的非光滑多体 …
