Israeli computer scientists and robotics experts have developed a robotic hand designed for fine finger tasks such as computer typing and piano playing, the Israel Institute of Technology (Technion) said in a statement on Wednesday.

The Technion team noted that the new robotic system could improve the lives of amputees, and is potentially capable of various other daily tasks, such as making coffee and changing a light bulb.

According to the statement, the researchers tackled a complex challenge in robotic prosthetic arms by focusing on the capability to execute intricate actions beyond simply grasping and moving objects.

The team has developed an ultrasound-based system that attaches to the forearm, which can read and interpret muscle movements. The system can understand the user's intentions and perform intricate and delicate finger gestures.

Meanwhile, unlike existing methods, the system does not require sensor stickers attached to the skin to interpret muscle signals.

The researchers said the system is expected to be a significant leap forward in the field of prosthetics, providing many users with an improved quality of life.
