Researchers at Harvard University have developed soft rubbery robotic fingers that are both flexible and fast enough to play a simple tune on a piano.
The fingers are currently being used in stroke rehabilitation, where previous versions were gentile enough to pick up flowers but not fast enough to play the piano. By limiting the amount of air required to fill each of the small chambers has sped up the response time of the actuators to around 50ms.
Not only are these actuators fast and capable of delicate movement, they’re also long lasting. After testing them for a million cycles they showed no sign of breakdown.
