Monumental Labs has taught an industrial robot arm the ancient art of stone carving, turning massive blocks of marble into intricate sculptures with unnerving precision. The New York-based startup uses 7-axis robots to handle the rough milling, a process they claim can eventually cut fabrication costs by up to 90%, before human artisans apply the final, irreplaceable touches. Looks like Michelangelo’s next apprentice might need a software update instead of a new chisel.
