The FDC Symbiotic Autonomous Initiative has just published its White Paper on the status and trends in autonomous systems. A part of that paper focuses on human augmentation and points out that this is happening today.
An example that just came under my eyes if the exoskeleton being tested by Ford workers in the Ford assembly line at Wayne.
The exoskeleton is a wearable robot produced by Ekso Bionics specifically adapted to the needs of Ford workers operating in an assembly line (see clip). It provides arm support, highly decreasing the fatigue of keeping your arm high as you are performing overhead tasks like fastening bolts on the car chassis.
The robot is composed by sensors and motors that can provide lift assistance to the arms up to 6.8kg. It has been designed to increase safety on the job and decrease fatigue. New version will allow workers to handle increased weight, actually augmenting their strength.
So far it has been used on a trial base at the Ford plant. The trial was supposed to end in August 2017 but the workers involved have pressed to keep using them so they are still in use.
