Colloquium 657 - Recent Advances in Non-Smooth Dynamics (NSD2025) is a specialised forum dedicated to bringing together leading researchers, engineers, and industry professionals to explore the forefront of non-smooth dynamical systems. These systems, characterised by abrupt changes in behaviour, are increasingly pivotal across various engineering and technological applications. From mechanical linkages and automotive subsystems, such as gears and bearings, to flexible multibody systems like beams and cables, non-smooth dynamics present unique challenges and opportunities that are crucial to modern innovation.

As industries shift towards lightweight, flexible components designed for high-speed operations, the relevance of non-smooth phenomena has grown significantly. This colloquium will highlight their impact in fields such as precision manufacturing, machine tooling, and metal cutting, sectors that are driving the transition towards Industry 5.0 - a new industrial paradigm focused on advanced technologies and global competitiveness. These areas are of particular interest to nations in Europe that are positioning themselves at the cutting edge of technological development.

In addition to engineering applications, non-smooth dynamics play a vital role in robotics, especially in systems designed to navigate complex environments filled with obstacles, uneven terrain, or confined spaces. Effective management of these dynamics is essential for the precise control and agile movement required in modern robotic systems, making this colloquium a critical event for those involved in robotics research and development.

NSD2025 will feature a rich program that delves into both the foundational theories and practical applications of non-smooth dynamics. By fostering interdisciplinary collaboration and knowledge exchange, the event aims to advance the understanding and application of these systems in addressing emerging technological challenges.
