When controlling a powered upper limb prosthesis it is important not only to know how to move the device, but also when not to move. A novel approach to pattern recognition control, using a selective multiclass one-versus-one classification scheme has been shown to be capable of rejecting unintended motions. This method was shown to outperform other popular classification schemes when presented with...
The human hand is a complex system, with a large number of degrees of freedom (DoFs), sensors embedded in its structure, actuators and tendons, and a complex hierarchical control. Despite this complexity, the efforts required to the user to carry out the different movements are quite small. On the contrary, prosthetic hands are just a pale replication of the natural hand, with significantly reduced...
An Articulated hand model was designed and built by CAD-CAM software, analyzed by finite element in the structure; the hand was made for a 3D printer in a first time, the construction of each finger suggested a mathematical model that describes the Inertia Matrix, Gravitational Matrix, and the Coreolis Matrix; the resulting mathematical model is three degrees of freedom, the finger control is based...
