Smart modular bricks identify their collective shapes through local communication

The short version

• Researchers published a study demonstrating virtual and physical smart bricks that recognize the complete shape they construct using only local interactions.[Scientific American]
• Simulated cubes identified categories with 85 to 100 percent accuracy and sustained recognition when partially removed, while physical tests reached 100 percent accuracy.[Scientific American]
• The project could eventually inform self-assembling modular robots and interactive toys, according to researchers.[Scientific American]

Key facts

• Researchers published findings in Nature Communications showing smart bricks that rely on biological self-organization principles.[Scientific American]
• Simulated cubes tested across nearly 500 shapes in seven categories achieved 85 to 100 percent classification accuracy, with houses proving the most challenging.[Scientific American]
• Virtual blocks often retained shape identification after a 15 percent loss and could determine missing units to regenerate neighbors.[Scientific American]
• Physical prototypes with internal circuits achieved 100 percent accuracy when assemblies of up to 197 blocks identified their shape.[Scientific American]
