Design of a control system for a medical wrist rehabilitation device

Abstract

The development of a new control system for a medical wrist rehabilitation device consists basically in the design of an intuitive controllable mechanism that aims to accept the parameters defined by the user and to respond adequately to that request. Two motors (a brushless motor “AEO A2830” and a stepper motor “Superior Electric M062”) are controlled by an Arduino development board, which receives and processes the instructions for the motors as well as for the acquisition software developed in LabVIEW (by National Instruments™). Two methods were used to define the interface between the user and therehabilitation mechanism, one of which is oriented to the electronic hardware and other one to the data acquisition software: the commands and instructions are addressed to the first one, while all the information is collected and registered on the second one. Since such rehabilitation mechanisms already exist, it is intended that the drawbacks of such equipment should also be addressed in the purpose of this study, complementing a gap in the health area.
