This 3D printed robot hand can play Mario University of Maryland
A 3D-printed robotic hand controlled by pressurised water can complete the first level of classic computer game Super Mario Bros in less than 90 seconds.
Ryan Sochol and his team at the University of Maryland were able to 3D print the hand in a single operation using a machine that can deposit hard plastic, a rubber-like polymer and a water-soluble “sacrificial” material.
