🦾 Scientists Created an AI Hand That "Thinks" for Itself
Researchers at Memorial University of Newfoundland in Canada have developed a prosthetic hand with artificial intelligence that autonomously recognizes and grasps objects—without requiring signals from the user.
💡 The Idea
Most modern bionic prosthetics operate via electrical signals from muscle contractions, which are picked up by special sensors. However, this approach differs significantly from natural movements, requires extensive training, and demands considerable physical and mental effort.
The new prosthetic hand does not rely on any signals from its user—its movements are entirely powered by AI. The user simply brings the hand close to an object, and the model identifies it in real time through a built-in camera, as well as sensors detecting both touch and motion. AI also determines the appropriate grip and force needed to pick it up.
The model was trained on video footage of the prosthetic prototype interacting with various objects, such as a water bottle, a banana, and a ping-pong ball. The AI-powered hand successfully grasps 95% of objects, including those not encountered during training.
AI has the potential to make prosthetics intuitive and reliable, says senior developer Xianta Jiang. People will be able to lift cups, open doors, and perform other tasks naturally, without constantly thinking about each movement.
