Scientists build a working robotic thumb anyone can wear

Researchers have developed EgoThumb, a wearable robotic thumb that attaches to a user's hand to provide an extra digit. The system uses a palm-facing camera to see what the hand is holding and forearm-mounted motors to control the thumb's movement, allowing wearers to hold objects while their natural fingers perform other actions, like stirring a cup's contents.

The innovation demonstrates a practical approach to human augmentation, improving dexterity for everyday tasks without requiring complex brain-computer interfaces. This points toward a future where wearable robotics seamlessly extend human capabilities for both assistive needs and general productivity, moving beyond traditional prosthetics to genuine enhancement.
