The Smart Orthotics system uses the Arduino MEGA microcontroller to receive sensor data and control the motors.The Arduino MEGA
The Arduino is connected to 2 H-Bridge motor driver chips to control the motors.
The motor driver uses a power supply and custom-built adapter to power the motors.
The sensors are distributed across the shoe to detect how the user's foot is oriented. This involves the placement of large, medium and small force sensors and flex sensors across the arches of the sole.
The sensors are placed onto the surface of the shoe as shown below
The sensors are connected to the 2 Analog to Digital Converter to convert the data from the 19 analog sensors to digital serial signal.
The ADC is placed under the board and connected to the arduino to process the signal.
