change empty world to gazebo inbuilt cafe #48

Closed Karsten1987 closed 5 years ago

Karsten1987 commented 5 years ago

Just an idea, but we could change the default empty world to something a bit more interesting like the inbuilt gazebo cafe. THere are some people walking around and some tables. Screenshot from 2019-06-06 17-03-25

second to it I changed the alignment of the rqt_gui to split horizontally in order to maximize the camera view Screenshot from 2019-06-06 17-21-25

I like the idea: Is there a way to make sure all the models are downloaded ahead of time in case we need to run this with limited internet connexion ?

:+1: If this is the same perspective as the one we'll use earlier for rqt_graph, I'd recommend defaulting to the opposite (rqt_graph window big, rqt_image_view_small)

Is there a magic command to make them walk?

Right now they're doing ... their own thing: Walking__they_said

Karsten1987 commented 5 years ago

for me they walk right after opening. @chapulina is there more to it?

Do you see any error messages printed? Maybe it's not loading libActorPlugin?

After you download it the first time, the models are cached in ~/.gazebo/models

I think they were just stuck in a local minima of their obstacle avoidance.

Running it again I saw them walk for ~1min before they got stuck in a different place

Ha, totally, I also see them eventually get stuck if I change the real time update rate to 0 (run as fast as possible). It's interesting that both of them always stop at the same time, and sometimes they recover after a while.

well we'll just :crossed_fingers: then

I actually believe resizing to a fix size doesn't make much sense, because in the end it depends on your screen and resolution etc. It should be fairly trivial to resize it on the fly.
