This article talks about the caterpillar, which can curl into a wheel and roll away when in danger. They can do so at incredibly high speeds, and they contain one of the “fastest self-propelled wheeling behaviors” in nature. Implementing the caterpillar’s rolling capabilities, scientists have been able to develop more efficient forms of locomotion through the caterpillar. In addition

This study consisted of multiple trials in which caterpillars were triggered to roll to escape danger. The trial studied how the caterpillars went into the rolling position (backawards), and the speed at which they rolled away. Additionally using the soft-bodied properties of the caterpillar, the team constructed a similar soft bodied robot and tested its ability to roll.

While the rolling mechanism has its challenges and limitations, it does open up the discussion for new types of locomotion that can be implemented into tech machinery and can help advance soft bodied machinery.
