Right now i have working a pioneer dx3 with navigation and gmapping. The robot learns dynamically from gmapping and navigates the environment. But i need to navigate with moving people in the environment and I dont know how to accomplish it. Ive seen that eband_local_planner works, but as the person moves the path the person just walks is marked as obstacle. So i need to be able to have an environment of moving people and clear the path they walk. Any ideas will be appreciated

Hi, the task of robot motion planning and navigation with moving people is a very difficult task, and it is still focus of intense research. I believe there is no off-the-shelf solution for it in ROS.

If you want any ideas on how to do it, I suggest searching on the topics of museum robot guides, assistance robotics, motion planning in dynamic environments, human path modelling and prediction, and others...

@Procópio Silveira Stein thanks, one more question do you know if it is possible to dynamically change the local planner? for instance if a person is detected change from one to another? Thanks

I'm not sure about that. I implemented a solution where I had multiple navigation modules, and I switched the name of the topics to use one or another. I suggest you create a new question, maybe someone can help you better.
