<div>I fulfilled a 3 year long dream to create a dartboard where you
get a bullseye every time thanks to some engineering. 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. Then we took it to a bar to see what people
would think of it: https://www.youtube.com/watch?v=MHTizZ_XcUM</div>
