Help Required! Changing Subscribed Topics of a Package
Greeting friends, I am currently working on a low cost method of mapping and I have decided to use ultrasonic to do it.
Ultrasonic Range Package: https://github.com/sharvashish/Obstac...
Mapping Package: http://wiki.ros.org/gmapping
The problem is the ultrasonic publishes a "sensor" topic while the mapping subscribes to "scan". Is there a method to make the mapping package subscribe to "sensor" instead?
Cheers, Thanks for your time.
