Mars Perseverance Rover Fiducial Marker

thingiverse

If you look at pictures of the Perseverance rover currently carrying out fantastic science on Mars you'll see it is covered in these small stickers. Called fiducial markers they are used by machine vision systems to calibrate the rover or manually back on earth analysts use them to help take measurements in images. I decided I wanted some for my workboxes etc so made this design in inkscape to use on my vinyl cutter.
