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. <o:p></o:p></span></p>
