Wayan Sumardana from Bali, Indonesia, made himself a bionic arm in his workshop in the village of Nyuh Tebel in the Karangasem regency.
Also known as Tawan, he suffered a mild stroke six months ago that paralyzed his left arm and hand, making him unable to work.
One day he saw his son crying because the poor lad didn’t have any money for snacks. That very moment, he knew he had to do something.
Obsessed with machine since childhood and with his knowledge in electrical engineering, the welder came up with an idea to make a bionic arm machine out of junk.
He then made a ‘neurotransmitter-like head band’ that send signals from his brain and amplified to his robotic arm.
Tawan said, “It’s similar to a lie detector. There are electrodes attached to my scalp, whose functions are to take small signals from the head. These signals would not be detected without this device. The signal is brought forward to an enlarged signal and then taken to the micro-control in my back and transferred to the front.”
“For example, I intend to move this part. Are all part of this activity, but depending on our needs. If the tool is not active, my hand silently sticks to the body. The process works like a dynamo; if there is a shortcut, it remains quiet but spends more energy,” he further explained.
