Amsterdam, Netherlands – Researchers at the University of Amsterdam recently conducted a study showcasing the unique behavior of topological solitons in a robotic metamaterial. By harnessing non-reciprocal interactions, the team aims to revolutionize materials science and robotics, introducing new possibilities for self-propelled motion and advanced functionality.
Topological solitons, which resemble particles in their behavior, are wave-like entities that can move around while retaining their shape. These solitons are integral to various natural and technological processes, from coiled telephone cords to proteins and even black holes. Researchers are now exploring how these solitons, when combined with non-reciprocal interactions, can blur the boundaries between materials and machines, creating lifelike and animate materials.
The study delves into the Machine Materials Laboratory at the University of Amsterdam, where researchers have been designing metamaterials – artificial materials and robotic systems that interact with their environment in a programmable manner. The team’s focus on understanding the interplay between non-reciprocal interactions and topological solitons has led to groundbreaking discoveries in the field.
In the study, researchers developed a soliton-hosting metamaterial consisting of a chain of rotating rods linked by elastic bands. Each rod, equipped with a motor, interacts non-reciprocally with its neighbors, creating solitons where different sections of the chain meet. These solitons, when set in motion by the motors, move in a unidirectional manner, akin to a chain of falling dominoes.
The implications of this research go beyond theoretical physics, extending into practical applications in technology and robotics. The ability to control the motion of waves, enable information processing capabilities, and enhance robotic functionalities through topological solitons opens up a new realm of possibilities. By harnessing the domino effect of solitons in metamaterials, researchers are paving the way for advancements in engineering and design.
Overall, the study sheds light on the potential of non-reciprocal topological solitons in active metamaterials, offering insights into the future of materials science, robotics, and technological innovation.
