- Using two MCU according to function. (Odroid U3and Odroid shield)
- Easy to code
- Fast enough to take a picture
##3. Concept design
- We use two MCU(Odroid U3_main mcu, Odroid shield _sub mcu) according to functions for much faster speed, much easier coding.
- We take some pictures and save data effectively and control sub mcu by using Odroid U3(Ubuntu).
- We control sensors(GPS, WIFI, IMU) and motors easily by using Odroid shield(Arduino IDE).
- Odroid U3 uses Ubuntu. It operates camera(Cam.cpp) and stores data log(Datalog.h, Datalog.cpp). And control Odroid shield(log.cpp).
- Odroid Shield operates like a Arduino Uno, so we use Arduino IDE. Arduino IDE is very useful to code sensors. So Odroid Shield controls rover(Whole system.ino) and sensors(IMU.h, IMU.cpp, MAX.h, MAX.cpp, ESP8266_P2P.h, ESP8266_P2P.cpp).
- Odroid U3 and Odroid shield communicate with each other by using Serial(arduino-serial-lib.h, arduino-serial-lib.c).
