DNA type multi-DOF flexible robot

We have developed a multi-DOF flexible robot modeled on deoxyribonucleic acid (DNA), the basis of heredity. DNA consists of bases, phosphate, and sugars that form a double helix, which can form a superhelix. In the present study, this double helix was modeled as a serial mechanism of 3-DOF basic units. The results of simulations with this model showed that it can form a superhelix. In addition, we built a robot consisting of 10 units with shape memory alloy to demonstrate that a superhelix can be developed.
