Inventor and former NASA engineer (and world's coolest uncle) Mark Rober debuts his latest project, which took him three years to perfect, a moving dartboard that allows even novice (or drunk) dart players to score a perfect bullseye with every throw.
"Basically, you throw a dart and then a Vicon motion capture system tracks the dart in the air. We use those x,y,z positions in matlab to predict where the dart will land using some regression analysis. Once we know where it will land, we move the board to the right spot using 6 stepper motors that attach to the back of the board using fishing line. All of this happens in 400ms or so."Previously: Mark Builds the World's Largest Nerf Gun
