Army vet takes us closer to Blade Runner era by building cyborg stingray

It almost seems like just yesterday that the world was introduced to Roy Batty, one of the most memorable cyborgs on the silver screen, a synthetic human who not only has the immense courage, intellect and abilities to free his fellow "replicants" from the yoke of tyranny but also exhibits a profound humanity by saving a Blade Runner, the very kind trying to eliminate his breed. It's no robot guide dog - but this wearable aims to help blind people safely move With expertise in tech to help robots detect and avoid obstacles, two Italian engineers have now turned their energies to making a device for the blind. This current aquatic cyborg may not be as memorable as yet to the one enshrined by Rutger Hauer in Ridley Scott's adaptation of Philip K Dick's novel Do Androids Dream of Electric Sheep? but it certainly has electrified the world by its birth, and the possibilities that it brings with it. Kevin Kit Parker, a former U.S. Army paratrooper, who completed two tours of duty in Afghanistan, leads a research team at Harvard University's Disease Biophysics Group that produced the stingray cyborg. The half-animal, half-machine is 16 millimetres long, weighs 10 grams and is about the size of a penny.
