North Carolina State University engineers have achieved a breakthrough in origami-inspired robotics, developing a novel methodology that enables a single, cube-shaped robotic structure to be reconfigured into over 1,000 distinct forms using just three active motors. The breakthrough could lay the groundwork for adaptable artificial systems capable of tackling multiple functionalities and even bearing weight – think modular robotic structures used in construction, for example?
“Researchers are seeking to develop a system that can generate a wide range of complex shapes using only a limited number of actuators, according to associate professor Jie Yin.” By leveraging a biomimetic approach, we’re drawing inspiration from natural hierarchies, such as the layered structure of muscle fibers, and applying it to the design of a reconfigurable robot utilizing plastic cubes.
Researchers at NC State successfully fabricated hollow, plastic cubes using a 3D printer and constructed a total of 36 units, incorporating rotating hinges, with some featuring metallic pins for mounting purposes and others equipped with wireless activation via motors.
Researchers successfully transformed over 1,000 distinct shapes from a set of cubes using just three dynamic motors. The structures encompassed tunnel-like edifices, bridge-like constructions, and intricate multi-story complexes.
Transformer robots, unencumbered by physical constraints, can move freely in any direction – forwards, backwards, or even sideways – without the need for feet, thanks to their ability to manipulate the shape of their constructions. The bots’ morphing process may unfold rapidly, transforming them from a flat, open design to a more complex, box-like structure that is either partially or fully enclosed. The robots are capable of carrying loads that are approximately three times their own weight.
Next, the researchers will aim to further enhance the capabilities of the transformer bots.
Yanbin Li, an NC State postdoctoral researcher and co-corresponding author of the study, emphasized the necessity for building a robust structure capable of supporting increased loads. How do we envision designing the fundamental structure capable of transforming into an automotive form? We must also consider reviewing our facilities’ designs in conjunction with innovative technologies such as autonomous robots.
According to Antonio Di Lallo, an NC State postdoctoral researcher and co-lead author of the study, “these structures hold potential as deployable, adaptable space robots and habitats.” “It’s a modular design, allowing you to easily transport and assemble the structure in various configurations, whether as a temporary shelter or long-term habitat, with the option to disassemble and reconfigure as needed.”
“For customers, simplicity in assembly and regulation is paramount,” Yin emphasized.
