Hello again. I ordered those two without any additional servo motor, so I have to put them to dedect left and right.
How can I calculate what is best angle to go with? Or design? Also i have two DC motors with gears and stuff, they work well.
I was thinking one front and one back, but if I had atleast one servo. Or two in front, everyone in their angle.
placement
The consensus seems to be: place them up front and let them "cross firelines". So the right one looks a bit left and the left one looks a bit right. Also make sure they are not way up front. Place them (if possible) a bit further back. That way you will prevent an incorrect reading when objects are REALLY close by.

Yeah that is what I was
Yeah that is what I was thinking about too. Maybe I will put them like that :). Now need to wait them to arrive.
All at once
I didn’t had plan to fire them all at once that is for sure. Will put them at back so it will prevent from bad measures.
Will make those cross , but both pointing almost straight , but still a some angle (10°)
They are saying to have them

is point where I will mount those sonar sensors.
Now the question, can I fire ultrasound sensor when is robot moving? That would simplify things.
"can I fire ultrasound
"can I fire ultrasound sensor when is robot moving"
Yes you can!
That’s hot
Wow cool!
I think I just found round plastic box to put stuff inside.
I could be wrong here, and
I could be wrong here, and perhaps you already know this, but I want to make sure you know what in the programming you should not fire the two ultrasonic sensors at the same time (or very close together) or they might hear the signal sent by the other sensor and you’ll have incorrect measurements.
Hehe
Yes I know about ghosting and such thing. Thanks nevertheless.

Started building a robot. With the “hard paper” of the box and lot’s of tape, it’s quite solid. Motors is already mounted with L293D on breadboard, breadboard is “glued” to robot. The AtMega8 is still sitting and two SRF 04 still need to get mounted.
