rosbridge - communicate with ros using another Laptop
I am following this example: http://wiki.ros.org/roslibjs/Tutorial...
I have two laptops, one is running Ubuntu with ROS; the other is running Windows. What I want to do is to control ROS using a non-ROS platform and I chose to use webpages running on browsers.
Experiment 1: Both browser(client) and rosbridge-server on a same computer
It works! And green "connected" showed up. Actually, both
ros.connect('ws://192.168.1.109:9090/');
and
ros.connect('ws://localhost:9090/');
works. Successful message of connected shows.
Experiment 2: Browser is running on another PC in the same LAN
I tried to use the following code in html. "192.168.1.109" is the IP address of the computer which is hosting the rosbridge-server in LAN. The LAN is setup through a TPLINK wireless router.
ros.connect('ws://192.168.1.109:9090/');
I could not get successful connected message.
When I typed http://192.168.1.109:9090/ in my browser in Windows, the following info showed up:
Can "Upgrade" only to "WebSocket".
There is some information showed up! So I guess there is some sort of connection!
However, I just cannot get the simple.html run right with successful message of "Connected".
Why is that?
