Using a third robotic thumb to play the piano

An extra robotic thumb can be controlled well enough to allow eleven fingers to play the piano!

Professional pianists put the robot finger to the test on a grand piano.

The majority of robotic limb research for healthy humans currently focuses on grasping items and lowering the workload of industrial workers. Experts in robotics at Imperial College London, on the other hand, were concerned about the possibility of reinventing music for pianists.

The robotic third thumb allows you to reach a larger number of chords and notes that would otherwise be beyond of reach. With only ten fingers, it is also possible to make impossible chords.

Aldo Faisal and colleagues at Imperial College London have been working on a robotic "third thumb" that attaches to the user's hand next to the little finger since 2015. The user can control his or her thumb by sending electrical impulses from his or her foot movement.

Signals from the user's foot operate the supernumerary robotic thumb (SR3T), which has two degrees of freedom. In one hour, a pianist may learn to play the piano with 11 fingers, according to the study.

The supernumerary robotic third thumb was developed to help pianists press piano keys beyond their natural range, resulting in a functional improvement in their skills and the technical feasibility of playing with 11 fingers. Sensors, motors, and a human interface algorithm are used to control the robotic finger's movement in real time. The usefulness of the robotic finger to perform musical pieces on a grand piano was demonstrated in a proof-of-concept validation exercise.
