Block diagram for whole system
Based on figure above, it can be seen that the input, process and output part.
The Input part
The system starts when EMG signal detected by surface EMG electrode. Surface EMG electrode need be used because it is non invasive and safe to the user. Next the signal will be filtered and amplified by AD620 IC.
The Processing part
In this stage, the decomposition of EMG signal is processed by the EMG circuit design.
The Output part
For the final stage, the signal in voltage condition will be powered the motor circuit to move the EMG electric wheelchair.
