4. Obstacle Avoidance Three Ultrasonic sensor Monitoring front, left, right Setting threshold value When distance < threshold value, backwards and go the other direction, when only front below threshold, default right

5. Web Cam Special Sensor Detect color red, when red account for relatively large area of the screen. Meanwhile, temperature hit threshold value, give alarm signal. OpenCV automatically email and text to designed account/number.
