Im wroking on a Robot that do the mapping, I'm using UltraSonic Sensors, IMU and Hall Sensors From the BLDC Motor, Arduino Mega 2560 and ROS Kinetic.

The next step is the obstacle avoidance. So the question is: How can I do obstacle avoidance using Lasersan data ???

one important requirement: do you have a laser scanner or similar device? Ultrasonic sensors != laser scanners.

I have 3 ultrasonic sensors, I converted it to a Laserscan

The tutorials on Navigation stack would be the right place to start (http://wiki.ros.org/navigation). The turtlebot implementation is a good example to see gmapping and amcl in action (https://github.com/turtlebot/turtlebot_apps/tree/indigo/turtlebot_navigation). Just remember that once you create a map, the path generation in that map is independent of the sensors.
