A team at NC State enabled just three active motors to change a single plastic cubed structure into over 1,000 different shapes.
A team at North Carolina State University’s method enables just three active motors to change a single plastic cubed structure into over 1,000 different shapes.
“Here we use a hierarchical concept observed in nature – like layered muscle fibers – but with plastic cubes to create a transforming robot,” said Jie Yin, associate professor of mechanical and aerospace engineering at NC State and co-corresponding author of the study, in aFor biological and artificial systems to be multifunctional and allow for adaptability to a variety of contexts, they must possess versatile shape-morphing capabilities.
According to researchers, despite significant breakthroughs, artificial systems have yet to match the diversity and efficiency of their biological counterparts; the key to shaping versatility is mobility and degrees of freedom . The group suggested a hierarchical architecture of spatial closed-loop processes as a solution to these problems. By substituting flexible, multi-level structures for inflexible connections, these systems allow for a wide range of reconfigurable megastructures with infinite design options that strike a balance between actuation efficiency and variety.The project aimed to achieve a variety of versatile shapes using the fewest number of actuators to power the shapeshifting.
