Apparently, in another robotic development, Berkeley Bionics in the United States is already working on its second generation exoskeleton suit for hikers, emergency/rescue personnel and military. The company originally showed off their exoskeleton back in 2005 and has steadily improved the design. Like the HAL, the contraption consists of leg braces, a 1.2 lbs battery and a microcomputer. There’s also a back frame for military style rucksacks. More on both here
