I'm happy to be the first one to write a topic on this forum session.
I'm mostly a beginner with Arduino.
I'm loosing my mind in finding a way to measure the distance between two point.+
I can can consider the A point as fixed and initial speed and position of B (moving) as 0.
I would like to have a precision of about + or - 10 cm for my project.
I'm using a Razor - 6DOF http://www.sparkfun.com/products/10010
For the moment i'm considering just data coming from y axis moving on a flat surface and in a linear direction along the axe.
I'm not finding any method to read a real distance covered.
In fact I have nice result if i'm not accelerating to fast of too slow. Moreover if I shake the sensor I get kilometers without any reason.
Can you suggest me something? Should I abandon this way?
I found on the internet that some company is selling something similar to inertial navigation system and that something similar was used in the 60s for ballistic rockets so I'm not loosing fait in this project.
Please help me.
I already tried other technologies like the RSSI from Xbee radio to measure distances but without nice results even because I need to measure distances even when point B is moving behind walls.
I was proudly made in Italy like Arduino .
