Gait analysis in rehabilitation robot system using accelerator and gyroscope

Gait analysis is one of the basic subjects in rehabilitation robot system (RRS), this paper pulls forward a method for gait analyzing in RRS using gyroscope and accelerometer. It uses accelerator and gyroscope to acquire RRS's gait information. It designed a gait information acquiring system with A MCU stm32 collected the signals of sensors and transmitted them to the PC side via serial port; On the PC side, a program write in Matlab read data from the serial port and dynamically display and process it in real-time. RRS's gait characteristic is extracted by analyzing pitch angles and slant angle and signals' waveform of those sensors which are attached to the RRS.
