Elongating Mechanisms: FiloBot's 3D-Printed Morphogenesis


A team of soft robotics researchers from Italy and France has unveiled FiloBot, a unique robot that 3D prints its own body to extend its length. This innovative creation combines robotics and 3D printing, allowing the robot to grow in a vine-like manner. Controlled by a spinning head with a 3D printer, FiloBot can navigate unstructured environments and be programmed to grow towards light or against gravity, offering versatile applications such as environmental monitoring and autonomous structure construction.


In a remarkable fusion of robotics and 3D printing, a collaborative team of soft robotics researchers from Fondazione Istituto Italiano di Tecnologia and the University of Montpellier introduces FiloBot. This snake-shaped robot employs an intriguing mechanism where its head spins, 3D printing additional body mass as it elongates. Aptly named FiloBot, this creation is not only visually captivating but also boasts versatile functionalities.

The robot's head houses a 3D printer ink tube, containing a specific type of plastic, enabling the printing process. The coiling of body material behind the spinning head results in the robot's elongation. Moreover, FiloBot can be programmed to grow in specific directions, responding to environmental cues. Electronics within the head, coupled with sensors, regulate the printer's output, allowing control over the growth direction.

The potential applications of FiloBot are diverse and intriguing. Its adaptive behaviors make it suitable for monitoring or interacting with unstructured natural environments. Furthermore, it exhibits promise in constructing autonomous structures and assessing challenging terrains, estimating avalanche or landslide risks, and testing pollution levels in hard-to-reach areas.

The researchers envision FiloBot as a groundbreaking soft robot with applications ranging from environmental exploration to infrastructure development. The novel combination of soft robotics and 3D printing opens up possibilities for creating adaptable and versatile robotic systems.


In conclusion, FiloBot represents a leap forward in soft robotics, demonstrating a symbiotic relationship between 3D printing and robotic morphogenesis. Its ability to grow at will, responding to environmental stimuli, showcases the potential for innovative applications. FiloBot's unique design and functionality pave the way for advancements in monitoring natural environments, constructing autonomous structures, and addressing challenges in remote or hazardous terrains.
