This approach is rooted in the concept of agency, where the wearer can control the robotic body part precisely without having to articulate their commands.
Human augmentation and the third thumb
The researchers emphasize that these human-robotic devices should have minimal impact on the wearer’s body while providing maximum gain.
For example, Clode’s extra thumb is connected to two wrist-based motors that are wirelessly connected to microcontrollers on the wearer’s shoes or ankles, which are connected to pressure sensors underneath the big toes.
By pressing down on these sensors, the wearer can control the thumb, demonstrating how the robotic body part can be seamlessly integrated into the wearer’s movements.
Scientists from Cambridge University at the Royal Society studied how the brain interprets an extra robo-appendage and how it affects other motor functions.
The study with 600 participants ranging in age from three to 97 years old had remarkable results. 98% of the participants were able to use the extra thumb within the first minute. And move objects as instructed.
