hi,
i am new here. i want to use ultrasonic sensors..... for obstacle detection. i have thought of using acroname's ...SRF08 for my work.... did anyone use it before. i want some review. or else can anyone suggest some better rangemeters. how about laser range finders??
i want to use the data provided by the rangefinder, in a c++ program and use it in a path planning algorithim. can anybody help me regarding this.... anyone who has worked in path planning and stuff....i am giving a statement of the problem i am dealing, here...

The problem is defined below...
I have to mount the sensor in a Wheeled Mobile Robot.
Given an initial and final posture of the vehicle, that the robot
has to reach in an environment having unknown obstacles. The
obstacles r randomly scattered n the vehicle has no prior knowledge
of them. The vehicle has to sence the obstacles and their distance so
that the distance data can be used to decide the path on the basis of
that information. For this the distance measurement has to be done
from a reasonable distance with good accuracy. The sensor will be
mounted on a servo to loacate its angular orientation with respect to
the reference orientation. This way, the vehicle will move on the
basis of the sensor data till it reaches the destination point.
I guess my usage of the meter is quite clear. So anyone, who has
worked on a similar thing can please help me. I want a very accurate
sonar, which could communicate with the computer through serial port.
I want to use the data in a C++ program. So a good tutorial is also
needed.

Please also tell me, which method of distance measurement is more suitable. I do not want to use vision. If you have any specific technique, please let me know.
