I'm trying to build the rotors package {https://github.com/ethz-asl/rotors_simulator}

I followed the steps below.

-i need to install the dependencies using the .rosinstall files in the source of the RotorS package. but i can't figure how to do that.

$ mkdir -p ~/catkin_ws/src $ cd ~/catkin_ws/src
$ catkin_init_workspace  # initialize your catkin workspace 
$ wstool init
$ cd ~/catkin_ws/src
$ git clone git@github.com:ethz-asl/rotors_simulator.git
$ git clone git@github.com:ethz-asl/mav_comm.git
$ cd ~/catkin_ws/
$ catkin init  # If you haven't done this before.
$ catkin build

-I'm not sure how to use the files to install the dependencies. I read the documentation for rosinstall but I'm confused on which file to mention for path and URI. and how to install the packages.

  • I'm sorry if this is a basic question, I'm new to ros and I don't know all the features, can someone help me with it?

PS: I'm using Ubuntu Focal with ROS noetic.

The usual way is to use: rosinstall . <your_package>.rosinstall
