[Java-player-users] Gazebo is running strange

[Alexandre H. V. S. <ahv...@gm...>]

Hi, I'm trying do run a Java application with Gazebo and I noticed that the
execution of the application is making Gazebo be slow.

The robot is not showing a continuous movement, it is "jumping" along the
time. I have already noticed that the Gazebo timer (the time that is shown
on the interface) is stopping, the same as the robot.

Running " glxinfo | grep rendering " command I got " direct rendering: Yes =
"
.

I run the CircleWalk example (
http://java-player.sourceforge.net/docs/howto.pdf ) on Gazebo using
Javaclient and everything was right.

Looking the Wall Follower example (
http://java-player.sourceforge.net/examples/2.x/SpaceWandererExample.tgz ,
which were strange, with the robot 'jumping'), I saw a '
robot.runThreaded(-1, -1);' command.

When I put this command on CircleWalk example the same as Wall Follower
example occured... the robot started jumping...

So, I tried to remove the 'robot.runThreaded (-1, -1);' from Wall Follower
example and the robot stopped moving... the application only works with tha=
t
command.

I run the same application on Stage and all works fine.

Is there something I can do to make the robot movement continuous on Gazebo=
?

My computer is an Athlon XP 2400+, 512MB RAM, my video card is a GeForce4 M=
X
4000 AGP 8x with 128MB of memory.

Thanks.
