Right now I'm using an Hokuyo Scanning Range Finder (http://www.hokuyo-aut.jp/02sensor/07scanner/urg_04lx_ug01.html).
This will be connected to an Arduino that will format the data in arrays with 720 measures, each measure can have a value from 0 to 5600.
Since we are measuring a room/indoor environment, tha "jump" in in tha value may be big (think at measuring a close wall and the seeing an open door... the jump can send the value from 500 to 5600 ), but the compressing may be an idea. If I have understand in a good way the TCPIP protocol, this should "verify" that package it sents, while UDP doesn't, so I should be able using a TCPIP protocol to check if I send the entire set. So the second compressing scheme should be better. Is it right?
Here is the datasheet: NOT FOUND | HOKUYO AUTOMATIC CO., LTD.
Thanks for the help
