Robotic flexible artificial finger design using nanosized DC motors and gears for finger injuries

Abstract

This paper deals with a typical study and analysis of finger injuries. The proposed study investigates and proposes an artificial finger based on sensitivity studies which would be technically feasible with nanosized gears and motors. The studies are based on sensitivity analysis done on a test bed of a DC servo motor scaled down in a miniature fashion based on a development of a position index of the matrix evaluation. The analysis data is fed to a novel fuzzy preview controller which would anticipate the condition of the finger as ill-conditioned which will settle the final position of the finger. This entire logic would involve the fabrication of such a device with nanotechnology as the lookup table can be realized using a nanochip. The motion of the finger along the three axes is dependent on how the sensor value interprets the value and the motor causes the motion based on the measured values of the current and voltages which are interpreted by the closed-loop control scheme.
