Editor’s summary
Strategies for robot locomotion have often taken inspiration from animals. But robots still fall short when compared to the inherent performance of animals. Burden et al. review the literature and discuss why animals outrun robots in categories such as agility, range, and robustness. The authors highlight that, with few exceptions, engineering outperforms biology in the components critical for running, so they conclude that there must be as-yet-undiscovered principles of integration and control that give animals their advantage over robots. —Amos Matsiko
Abstract
Animals are much better at running than robots. The difference in performance arises in the important dimensions of agility, range, and robustness. To understand the underlying causes for this performance gap, we compare natural and artificial technologies in the five subsystems critical for running: power, frame, actuation, sensing, and control. With few exceptions, engineering technologies meet or exceed the performance of their biological counterparts. We conclude that biology’s advantage over engineering arises from better integration of subsystems, and we identify four fundamental obstacles that roboticists must overcome. Toward this goal, we highlight promising research directions that have outsized potential to help future running robots achieve animal-level performance.
