Design of Intelligent Rehabilitation Crutch Based on Accelerometer


Article Preview

In order to meet the daily needs of the elderly patients and walking ability of injury rehabilitation, design an intelligent rehabilitation crutch. This design combine with empowered walking aid’s mechanical features and robot technology, its signal is collected by MMA7260 accelerometer, this greatly improved the sensitivity direction without swerve on the plane through the analysis of the acceleration signal processing and controlling the velocity composition of three omnidirectional wheel rounds of synthesis of all to realize the intelligent walking stick of the whole direction and intellectuality of the walking aids. The motion mechanism of crutch using omnidirectional wheel structure and using ATmega 16 microcontroller to establish low-level control system. The crutch can move in any n of free movement. The kinematics analysis shows the design feasibility. In the manual and automatic control experiments, it can meet designer quarrymen’s and achieve design function.
