Cockroaches, Trains and Tanks Help Army Scientists Build Better Legged Robots

New research by Army scientists could lead to legged robots that are as efficient as wheeled or tracked battle buddies — a boon for dismounted infantry in rugged terrain, such as mountains or cluttered urban streets. That research was recently put together from digging through decades-old data on studying how mass, speed and power of animals could be measured. The research and formula that emerged were recently published in a paper in the peer-reviewed scientific journal PLOS ONE. The formula is important because it shows the same trend lines for how mass, power and speed relate to each other — regardless of whether what’s being measured is a cockroach or a tank. Researchers Alexander Kott, Sean Gart and Jason Pusey, all with the Army Research Laboratory, co-authored the paper that could contribute to future robotic vehicle development.
