Hi,

In my project i should do mapping and localization using only ultrasonic sensor and IMU. Most of mapping packages in ros use laserscan message, the ultrasonic sensor return a range message.

I am using 10 HC-SR04 ultrasonic sensor. ROS kinetic ubuntu 16.04. MPU-6050.

How can i construct a laser scanner message using the different readings sonar sensor ???

I don't think that this is a good idea. Also the question is: Why?
