No longer carry hefty backpack with yourself because the new 21st-century pack mule, called Exoskeleton could DO it for you !
Researchers in the MIT Media Lab's Biomechatronics Group have created a device to lighten the burden for soldiers and others who carry heavy packs and equipment.
Their invention, known as an exoskeleton, can support much of the weight of a heavy backpack and transfer that weight directly to the ground, effectively taking a load off the back of the person wearing the device.
The person wearing the exoskeleton places his or her feet in boots attached to a series of tubes that run up the leg to the backpack, transferring the weight of the backpack to the ground. Springs at the ankle and hip and a damping device at the knee allow the device to approximate the walking motion of a human leg, with a very small external power input (one watt).
