A new project in the field of soft robotics shows how microfluidics and 3D printing can be used to realize amazingly complex motion sequences. YouTuber “soiboi soft” has developed a salamander-like robot that moves with the help of pneumatic muscles. The construction is made entirely of flexible materials and is based on a network of microfluidic channels that can be controlled using compressed air.
The robot’s actuators are designed in such a way that they can assume different movement states through targeted pressure distribution. A total of eight different movement patterns can be realized – controlled by three compressed air lines. The soft muscles consist of several elastic layers in which precise channels are embedded. These channels can be produced using standard resin 3D printers or by molding, which makes the construction accessible outside of research laboratories.
The prototype is still attached to external compressed air lines via a kind of “leash”. Langfristig plant der Entwickler jedoch, eine autonome Version mit integrierter Luftversorgung und Steuerung zu realisieren. This would allow the Salamanderbot to move wirelessly – an important goal for many mobile soft robotics applications.
A few decades ago, the technical implementation of such systems would only have been conceivable in specialized research facilities. Thanks to advances in 3D printing, particularly in the field of high-resolution stereolithography and flexible materials, functional microfluidic structures can now be produced relatively easily.
