I started to create my URDF robot model, using ros tutorials as reference. But when I try to visualize the model using rviz, an error happens:
.Global Status: warning + Fixed frame: No tf data. Actual error: Fixed Frame [/map] does not exist
Robot Model (Robot Model):
- Status: Error
- base_link: No transform from [base_link] to [/map]
What am I missing here?
