Hi everyone,

I'm a studendt doing its Final Project, the goal is to create a drone in gazebo with ros2. I'm running gazebo 11.10.2 and ros2-humble. To start with this new technology for me, i've tried to run the code from https://github.com/chapulina/dolly, but when i try to launch the launch.py file the cmd shows me a message that i don't have the gazebo_ros package but i do have it installed. (I adjunt a link with a screenshot : https://postimg.cc/23H3S7Fq)

I've been following the video "https://www.youtube.com/watch?v=T4iRJqESQAk". I'll be very grateful if anyone can help me or can send any getting started guide. Have a nice day!
