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. Temperature Sensor and LCD
Temperature sensor Tmp36.
2*16 LCD.

6. Xbee Communication Xbee communicate each other
Receiver receive direction signal based on object location

7. IP Cam Special Sensor Detect base(color orange object).
After base is detected, park ranger will go towards to the it.
Problem : IP camera sometimes frozen. Not stable.

8. Summary What I’ve learned: How to build a robot from scratch.
Embedded C programming
OpenCV image processing
Solidworks
