hey guys ,, the subject says it all,
anyone can help me with narrowing that stupid 30 degrees beam?
i need to use this for mapping so i cant tolerate that much of angle spreading.
i also wouldnt want to use sharp-IRs cuz they dont provide you good ranges
the laser rangers also are incredibly expensive.
HELPPP
ive read that some people used the sonars for mapping but they didnt tell how they overcame this problem of beam spreading out..
thanks for any answers
