Robo-cheetah may 'save lives in TEN YEARS': Machine that runs faster than Usain Bolt could soon be on the battlefield
comments
It's one of the most advanced robots under development by the US military.
The cheetah, described as the 'Ferrari in the robotics world', could be used on the battlefield in just ten years, according to its creators.
The stealthy machine can run faster than Usain bolt, jumps 16 inches (40 cm) and gallops for 15 minutes - all while using less power than a microwave.

It is the creation of the Massachusetts Institute of Technology, who had to design key elements from scratch because of a lack of or shortcomings in existing technology.
That includes powerful, lightweight motors; electronics that control power for its 12 motors; and an algorithm that determines the amount of force a leg should exert within a split second.
This allows the machine to reach speeds of up to 30mph (48kph) over difficult terrain.
Insight gleaned from the design of their prototype could have real-world applications, including the design of revolutionary prosthetics, wearable technologies and all-terrain wheelchairs.
There are hopes the robot will be able to be used in search and rescue operations in hazardous or hostile environments where it's too risky to send a human rescuer.

'In the next 10 years, our goal is we are trying to make this robot to save a life,' said MIT Professor Sangbae Kim.
'When the robot is running, at every step, we calculate the appropriate amount of the force to the legs so that the robot can balance itself,' added MIT research scientist Hae-Won Park.
Sensors inside the robot measure the angle of the leg and that information is sent to an onboard computer that also organises data from the Inertial Measurement Unit which is also used to manoeuvre drones.
The project is funded by the US Department of Defense's Advanced Research Projects Agency, who is developing a similar robot being alongside Boston Dynamics.

The company says its version is powered by an off-board hydraulic pump and uses a boom-like device to keep it running in the centre of the treadmill.
Crafting the cheetah robot took five years of designing, testing, tweaking and plenty of confidence to ignore those who said electric motors aren't strong enough to propel a running mechanical cheetah powered by batteries.
Researchers had to exercise a lot of patience during test runs. The robot broke dozens of legs manufactured by 3D printers and reinforced with Kevlar strips and carbon fiber.
Strong, lightweight components make untethered running possible, including a carbon fiber-and-foam sandwich frame that can absorb the forces generated by running and jumping.
Some off-the-shelf components, including an Xbox controller for manoeuvring the robot and wireless internet communications for sending commands, were also used.
Each leg is propelled by three motors that can generate powerful forces at slow speeds.
Still, researchers continue to tweak their prototype, looking to add additional sensors that would eventually make the robot autonomous.
