I have questions about location tracking.
In my design, raspberry pi and Arduino uno is communicating via I2C.
Raspberry pi makes random value and send to Arudino.
Depends on random value Arduino control servo to move. (Forward, Left, Right)
(Forward : move 1 inch forward)
(Left : turn left 10 degree and 1 inch forward)
(Right : turn right 10 degree and 1 inch forward)
And I am using boe bot for robot car.
In this case, how can I detect location??
The size of map is 72x72(inchxinch). INDOOR!!
I want to track the boe bot. But I don't know how to track it.
I found 2 options to track location.
1. Accelerometer and Gyroscope.
2. Proxzy indoor GPS

I am not sure which one is better for my case.
Each option has problems.
Accelerometer and gyroscope can track the location, but the problem is error will be increased whenever boe bot moves.
And most of accelerometer and gyroscope use I2C communciation.
However, I am using I2C communication with Arduino.
I know I can use multiple devices for I2C Communication, but I do not know how...(If anyone knows it, could you show me sample code or tutorial site??)
For make sure, below problem is main reason why people do not use them??
Accelerometer will make more error if the boe bot moves only 1 inch..
Gyroscope will make more error if the boe bot turn more degrees..
No one used Proxyz indoor GPS.. (I need sample code, and tutorial for understanding how it works.)
Which option is better for me..?
Anyone can post sample code or tutorial for each option..?
