Visualizing rviz in another computer
Hi guys,
I am doing amcl on my robot and running rviz on another pc by using the publisher and listener method. But I am having a problem which I can't set estimated pose of my robot on the rviz. But I have no problem visualizing rviz on the pc of robot itself.
Fixed frame is set to /map.
Anyone face the same problem before? How do you solve it?
In rviz terminal:
[ INFO] [1389077566.411670728]: Setting pose: 10.008 -3.034 3.142 [frame=/map]
[ INFO] [1389077610.967860311]: Setting pose: 10.044 -3.009 3.142 [frame=/map]
[ INFO] [1389077693.039567267]: Setting pose: 10.044 -3.048 3.142 [frame=/map]
rostopic echo /initialpose:

I can see rostopic list and rosnode list.
Second trial
Finally can see rostopic echo initialpose, but pose in rviz still couldnt be moved. Rostopic echo amcl_pose give me the x,y,z of robot initial position of amcl preset parameters, fixed frame /map.
/initialpose

Hello!
A quick comment first: you spelled "initialpose" incorrectly in the rostopic command, I assume you get the same result with the correct spelling?
This problem usually inicates a networking problem between the two nodes. I'd suggest setting ROS_IP to the IP address of the computer you're setting it on, for example with export ROS_IP=192.168.1.2.
To test your network configuration, on the Rviz computer type rosnode ping amcl, you should hope to get valid ping replies, but if not then your problem is definitely with your network setup. In that case you should try just a regular ping 192.168.1.xxx on the rviz computer using the IP address of the robot computer and debug the network configuration from there. There's some good tutorials and troubleshooting at http://wiki.ros.org/ROS/NetworkSetup
Finally, the command roswtf (AKA ros where's the fire) can give you hints. If the above doesnt help could you edit your post with the output of roswtf?

I have no problem doing ping, so this mean nothing wrong with my network setup. But I can't do roswtf somehow. Post updated.

The regular ping did not work, so this is probably the issue. I see your nodes are on different subnets (192.168.2.x and 192.168.18.x), are you sure the two devices can communicate? Do you have firewalls in between subnets? And what about "rosnode ping rviz" from the robot computer?

Okay I have already make sure ping to robot and ping myself has no problem right now, rosnode ping amcl as well. I have updated my post.

Why do this happen when i can see changes in initialpose but no change in rviz and amcl_pose? amcl is not updated to the pose ?
