Real-time control of active ankle foot orthosis using LabVIEW and Compact-RIO

Abstract

The main aim of this research is to develop a standalone embedded system for the control of dorsiflexion or plantarflexion movement using surface Electromyography (sEMG) signals in an active ankle foot orthosis. The proposed control system consists of sEMG electrodes, National Instruments CompactRIO (NI cRIO), NI Analog Input Module, Digital output module, motor driver and a DC motor. NI compact RIO is a programmable automation controller which uses analog and digital I/O modules which acquires the required data and controls the hardware. CompactRIO is programmed by using NI LabVIEW.
