MO, the Obedient Machine

Meet MO, physics teachers and popularizers’ dream come true. MO isn’t just a very obedient machine, it is able to show the invisible. MO has the extraordinary ability to make graphs tangible.


With MO, no more cringing to graphs, make way for surprise and fascination ! A perfect match between design, electronics and coding, to bring to life the 3 sensors and 5 modes that make MO, the Obedient Machine.
