Mechanic I Wayan Sumardana, also known as Tawan, suffered a stroke six months ago and, as a result, his left arm was paralysed. But he did not let that stop him from working, so he put his machine engineering knowledge to work by making a "robotic arm" for himself. Here, he is photographed using that arm to weld a client's motorbike part at his garage in the village of Nyuh Tebel, Karangasem, Bali, Indonesia. Mr Tawan said he built the device, using mostly recycled materials, to help him move his left arm.
