| DARPA is working to create robots that don’t sacrifice speed for mobility on rough terrain. Now, the famous "Cheetah" robot has operated past 28 miles per hour, a record for legged robots. |
In the process, Cheetah also surpassed another very fast mover: Usain Bolt. According to the International Association of Athletics Federations, Bolt set the world speed record for a human in 2009 when he reached a peak speed of 27.78 mph for a 20-meter split during the 100-meter sprint. Cheetah was recently clocked at 28.3 mph for a 20-meter split. The Cheetah had a slight advantage over Bolt as it ran on a treadmill, the equivalent of a 28.3 mph tail wind, but most of the power Cheetah used was to swing its legs fast enough, not to propel itself forward.
Cheetah is being developed and tested under DARPA's Maximum Mobility and Manipulation (M3) program by Boston Dynamics. The increase in speed since results were last reported in March 2012 is due to improved control algorithms and a more powerful pump.
The M3 program pursues four parallel tracks of research and development: tool design, improvement of production methods and processes, improvement in control of robot mobility and manipulation, and prototype demonstration.
DARPA's intent with the Cheetah robot and its other robotics programs is to attempt to understand and engineer into robots certain core capabilities that living organisms have refined over millennia of evolution: efficient locomotion, manipulation of objects and adaptability to environments. By drawing inspiration from nature, DARPA gains technological building blocks that create possibilities for a whole range of robots suited to future Department of Defense missions.
“Modeling the robot after a cheetah is evocative and inspiring, but our goal is not to copy nature. What DARPA is doing with its robotics programs is attempting to understand and engineer into robots certain core capabilities that living organisms have refined over millennia of evolution: efficient locomotion, manipulation of objects and adaptability to environments,” said Gill Pratt, DARPA program manager. “Cheetahs happen to be beautiful examples of how natural engineering has created speed and agility across rough terrain. Our Cheetah bot borrows ideas from nature’s design to inform stride patterns, flexing and unflexing of parts like the back, placement of limbs and stability. What we gain through Cheetah and related research efforts are technological building blocks that create possibilities for a whole range of robots suited to future Department of Defense missions.”
