Move base with namespace

Hi,
I tried amcl & movebase with namespace. Ran into the following error.
The robot navigates to the goal position but does not avoid obstacles. Instead it just tries to run through obstacles.

roswtf
Found 1 error(s).
ERROR The following nodes should be connected but aren’t:

Hi,

Our friends at TheConstruct created a set of video tutorials explaining how to deal with multiple robots.
Please refer to:

This should give you all the necessary knowledge well explained.

Best,
Adam
