In my end of studies project, I have to make a robot that should do mapping and localization using only ultrasounds sensor. So for doing this i should convert sensor_msgs/LaserScan message to sensor_msgs/Range message.

My question: How can i do this ??

Hi,

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 ???

Why i can't build a map using the three ultrasonic sensors ??

Hi,

I am a beginner in ros.

I should make a robot follow a path giving in the simulator rviz. How can i do this in ros ???

Pleeeeeeeeeeeeeeeeease can some one help me!!

Thank's for helps.

Thank you so much bro, this is very helpful

When I shut down the node plush_odometry, I receive this warning instead of the warning described above: ~$ rosrun gmap

Can you more explain about this solution??
