➀ Researchers from Duke University have developed a system called SonicSense, which allows robots to interact with their environment through a robotic hand with microphones on its fingertips. The system captures vibrations and analyzes them to determine the material and shape of objects. ➁ SonicSense uses AI to identify objects with complex shapes and multiple materials, and it can learn from interactions to improve its recognition capabilities. ➂ The system is designed to be affordable and easy to integrate into robots, potentially enhancing their ability to navigate unpredictable environments.
