COLLEGE PARK, Md. The U.S. Army plans to cooperate in artificial intelligence research with teams led by the University of Maryland, College Park and in partnership with the University of Maryland, Baltimore County. The cooperative agreement brings together a collaborative of nearly 30 diverse experts in engineering, robotics, computer science, operations research, modeling and simulation, and cybersecurity.
With the Army s goal of seeking transformational advances in artificial intelligence and autonomy, Army and academic officials said this partnership will accelerate the development and deployment of safe, effective and resilient capabilities and technologies, from wearable devices to unmanned aircraft, that work intelligently and in cooperation with each other and with human actors across multiple environments.

What makes cheetah the fastest land mammal? Why aren t other animals, such as horses, as fast? While we haven t yet figured out why, we have some idea about how cheetahs, as it turns out, make use of a galloping gait at their fastest speeds, involving two different types of flight : one with the forelimbs and hind limbs beneath their body following a forelimb liftoff, called gathered flight, while another with the forelimbs and hind limbs stretched out after a hind limb liftoff, called extended flight (see Figure 1). Of these, the extended flight is what enables cheetahs to accelerate to high speeds, and it depends on ground reaction forces satisfying speci
