Some new robotic appliances aid construction workers in heavy, repetitive tasks.
One example of such a task is working a 40-pound grinder back and forth, sometimes while holding it overhead. The task requires immense strength and stamina, but it takes a toll on even the toughest workers.
New 'Zero G' suits and arms make the tools nearly weightless, while allowing great maneuverability. The appliances are not what you might think of as a robot. There aren't any computer chips, or power packs. The appliance is completely mechanical.
EksoZeroG, by Ekso Bionics, makes the tool nearly weightless, allowing workers to work longer and more accurately.
A Nevada carpenter, who uses the EksoZeroG arm, said: "Before, carpenters could get between 50 and 100 holes in a day by switching guys out, because it is just brutal. . . Now with [the EksoZeroG], on a good day, I can do 300 to 330 holes'one guy by himself."
