Welder builds mind-controlled prosthetic arm from scrap, but what’s the truth?
I Wayan Sumardana (a.k.a Tawan) is a 31-year-old welder from Indonesia claims to have made a mind-controlled robotic arm which aid him in his daily tasks. Yes, he made it all by himself from scrap metal and other parts. No doubting the locals call him Iron Man, as he goes on doing his daily chores with a mechanized left hand which has been paralyzed for a long time after an ailment, and doctors confirmed he has mind stroke. Based on his knowledge gained from the education as machine engineering student in high school, Wayan made it all from bike parts, computer hardware and many other scrap things.
Amazingly he has been able to pair it up with an EEG system which reads brain’s signals and moves the arm accordingly. Now, that is beyond belief as you can see him do tedious tasks with ease using the paralyzed left arm. He can lift weight of 10 kg using this arm and it gives him mechanical power to other tasks too.
MUST WATCH: Gesture-controlled robotic prosthetic arm
But this takes a toll on his brain as he has to concentrate a lot and focus on what he wants the robotic hand to do. This seems like a movie plot where an ordinary man creates a robotic arm and it all goes out of control after that.
Some doubt the creation and believe it is a hoax
However, Wayan has not had any such problems till now and he’s able to support his family of a wife and three children with the prosthetic arm to his rescue. Currently he has a workshop Banjar Tauman roadside Candidasa, Tenganan Pageringsingan and locals are just petrified by what he has achieved.
There are many sceptics who believe that the whole thing is a hoax and Wayan controls his hand without any assistance from the mechanical support. We cannot rule out that possibility without knowing the facts, but for now we’ll assume it is real and that in itself is an incredible achievement.
