Indonesian “Iron Man’ Allegedly Builds Brainwave-Controlled Robotic Arm from Scrap

Wayan Sutawan is being hailed as Indonesia’s very own Iron Man after building a robotic device that he claims can read signals from his brain allowing him to control his paralyzed left arm.

This literally unbelievable story started six months ago, when Sutawan suffered a stroke that left him with a paralyzed arm. Having studied a bit of mechanical engineering in high school, the father-of-three spent the next couple of months working on a robotic arm using spare parts that were just lying around in his garage. He finally created a strap-on mechanism for his paralyzed limb connected to a headband that he claims reads his brainwaves and transmits commands.

In a video report by Indonesia’s Kompas TV, Sutawan is seen strapping the device on to his left arm and covering his left hand with a thick rubber glove. He then puts on the headband, and after a moment’s concentration, the arm miraculously jerks to life. He is then able to use the paralyzed hand to perform delicate tasks. He’s also able to lift up to 10 kilograms of weight with the device on his left arm.

Although the story has gained a lot of attention on social media and other news networks, not everyone is buying it. Skeptics think the arm is fake, mainly because it doesn’t make any sense. Paralysis occurs when the brain cells that control a particular motor function are dead, and the brain can’t issue a command for that body part to move any more. So the idea that a headband can actually ‘read’ the brain’s signals and convey to them to the arm is rather implausible.

Others have other questions – assuming the headband could somehow detect brainwaves from dead brain cells – where did he store the processor needed to identify the brainwaves and translate them into mechanical motor functions? “How did he develop such sophisticated programming?” an Malaysian tech site SoyaCincau.com questions. “What kind of supercomputing power is being used to digest all that data?” Those are pertinent questions, especially since Sutawan makes a living as a simple welder.

The article continues to point out that “the glove that controls Tawan’s finger movements don’t have any actuators at all. So how could this contraption allow him to make the finger movements necessary to pick up and grip the solder in the video?” They think it’s more likely that Sutawan has a weak arm that needs some motorized help to function better, which is probably what the device is doing. “If you pay close attention to his left arm when he is inserting it into his mechanical contraption, you can see his wrist flick upwards before it enters his sleeve.”

In any case, Sutawan says that the robotic arm has helped him immensely – he was out of work only six months ago, but today, he’s able to support his wife and three children. “The tool is not perfect, but is tolerable and has helped me,” he said, humbly.

Interesting real-life Tony Stark story, but hopefully someone will investigate this groundbreaking invention a bit more thoroughly, before we start getting all excited about Wayan Sutawan building a real Arc reactor.
