Here is a myriapod robot that relies on variable body-axis flexibility to navigate. Developed by researchers from the Department of Mechanical Science and Bioengineering at Osaka University, this robot can turn without a complex control system thanks to its flexible couples. This robot was inspired by insects that make quick movement changes by controlling the dynamic instability in their motion.
The above video shows how this robot works.
