As the song goes “What doesn’t kill you makes you stronger”. This line can be related to Wayan Sumardana, a 31-year old welder by trade from Bali, Indonesia, who was able to innovate something amazing despite his social status and having just survived a mild stroke. He created his own mind-controlled bionic arm.
Wayan, or Tawan as people call him, was able to make a bionic arm from scratch using only tools and scrap metals from his workshop.

Tawan’s arm was left paralyzed after he suffered from a mild stroke. Being his family’s breadwinner, he had to find a way to be able to work. Using his enthusiasm and some knowledge in electrical engineering, he was able to create his own mind-controlled bionic arm.
He can transmit signals from his head to his bionic arms, so it can work like a real arm.
According to Tawan, his machine works like a lie detector. Electrodes are attached to his scalp, wherein it takes signals from his head. The signals are them amplified then analyzed in the micro-control on his back, then will be transmitted to his bionic arm.
“I want to motivate people who have strokes.” Tawan said.
