- Ultrasound imaging turns a robot hand into a skillful mimic
MIT researchers have developed a wristband with an ultrasound sticker to capture real-time muscle and tendon movements, enabling precise control of robotic hands and virtual objects. The device uses AI to translate ultrasound images into hand gestures, allowing wireless manipulation of robots for tasks like playing piano or shooting basketball.
- MIT researchers channel AI to turn hand gestures into robot training data
MIT researchers developed a wristband using ultrasound and AI to capture human hand gestures, enabling robots to mimic dexterous movements for tasks like housework and surgery. The device tracks muscle and tendon activity, achieving precise gesture replication within 120 milliseconds and supporting wireless operation.
