Duchenne Muscular Dystrophy (DMD) is a fatal condition that deteriorates the muscles in thousands of children – but it has almost no public support in Australia. To help "Save Our Sons" raise awareness of DMD, we invented the world’s first petition-signing robot arm. We called it "The Most Powerful Arm Ever Invented", because it has the power to save lives by signing the petition with your name - all at the click of a Facebook button. We gave it the same handwriting as a boy who suffers from DMD and lost the ability to write at an early age.
