I am working on the navigation stack of ros. I want to implement the following random video https://www.youtube.com/watch?v=RFdlX... This video is showing exactly what i want to implement. Kindly help me where can i find the source or tutorials so that i can understand and implement the same.
Regards
The tutorial on Sending goals to the navigation stack may get you started.
Thank you for your reply. I regret but i am not able to understand the prerequisite section of the tutorial. Is it necessary to use the two given links. Or can i simply run my own bot in gazebo and rviz and then check the cpp file?? And what exactly these two links are gonna perform?? Regards
I´m using the tutorial that you post But on this step "rostopic .. _base/goal" I got no answer, so calling "rostopic list" I found running "move_base_simple/goal" So I back to the "simple_navigation_goals.cpp" file and change only in line 11 "move_base" to "move_base_simple" but didn´t work.Help me?
Thank you @ahendrix . I have implemented the tutorial. I have used my bot to move a meter forward in my own loaded map. Now i want to send the command to the bot which could make the bot to move in a any desired location (as shown in the video link). Can anyone help with with such code?? Regards
but i want to make the user to send the goal on real time basis such that robot takes the input from user, moves to that location and so on. setting multiple goals and pre-defining them in the program wont do the job but i m not able to find any help from the net so far.
I am trying to modify the code to send multiple goals. So far, i am not able to successfully do that but trying. If anyone has the similar code, or can help me in this code, kindly revert. Thanks
Hi!
I would suggest you the follow_waypoints package, which seems quite convenient for what you're looking for. Also, since it's written in Python, it's pretty easy to understand and to modify/customize.
I've also created a short video showing how to use it, you can check it here.
Hi! Hoping it can be helpful to someone, I have wrote two posts about sending goals to the navigation stack with a Python node (with example code):
Sending a single goal (equivalent to the C++ tutorial), here.
Sending a sequence of goals (complete of simulation with a turtlebot robot), here.
Cheers!
@fiorellasibona sorry for the confusion, but I meant putting the examples in the answer. The reason is is to keep answers self-contained because files/pages can and do disappear from other sites making the answers not helpful
@fiorellasibona can you be more specific with your answer. I am also working on ros and i am using turtlebot3 burger. can you share how to run this code and what are pre requisites for this? i mean which packages to be installed and what sould be running before running this code.
@enthusiast.australia Hi! I think what you are looking for is available within the first post I have linked (The "Sending a single goal" tutorial). Needed packages and launching instructions are available... Let me know! Thank you
@fiorellasibona Answers that link to external resources are discouraged (as has been mentioned) because that content can and does disappear (which happened with this answer). If you could update your answer with the relevant content from that tutorial, that would make this answer useful.

Which robot are you using for run the Goals to the navigation stack?, because my robot are not with move_base and now I need another. thank you
I am using the "diff-wheeled-robot" as mentioned in the book "mastering ROS for robotics". U may find the files and codes mentioned in the book from the following link. "https://github.com/qboticslabs/mastering_ros" If you need only the robot , you may direct get the "chapter_3_codes".
works, thank you
