Cockroaches don't look like the most elegant of runners as they scurry out from under the refrigerator, but they could be a model for how to make robots move really fast without tripping or falling over, according to a new paper. In their research, Georgia Tech researchers Izaak Neveln, Amoolya Tirumalai and Simon Sponberg studied 17 cockroaches and 2,982 of their strides to come up with mathematical equations and principles for how they manage to scurry as they do. Work was also described in Futurity.
