Hy Guys,
I just have a little question. I'll appreciate your support.
I have worked with rosbridge and I don`t have any problem, But I want to launch a python file from html file. Something like that:
<html lang="en"> .... rosrun filename.py.
Thanks. I'll appreciate your support.
John
I suspect this is not possible, but I have not used rosbridge much.
No, this is not possible. @JohnPa: rosbridge is really just that, a bridge. It allows you to connect to a ROS node graph using a JSON based API. Anything you can do with a regular ROS node can be done from javascript. If you want a "python file" to be started based on some event, ..
.. you'll have to create a ROS node that either listens on a topic and publish a message to that topic from javascript, or make the node expose a service and have your html page (again, with javascript) invoke that service. That ROS node can then do anything, including starting your Python file.
Thanks! So much. @gvdhoom
Due to your answer I have understood better. This is the solution:
var listener2 = new ROSLIB.Topic({
ros : rbServer,
name : '/chatter',
messageType : 'std_msgs/String'
});
listener2.subscribe(function(message) {
console.log('Received message on ' + listener2.name + ': ' + message.data);
document.write(message.data);
//listener.unsubscribe();
var str = new ROSLIB.Message({
data : message.data
});
jptopic.publish(str);
});
var jptopic = new ROSLIB.Topic({
ros : rbServer,
name : '/chatter2',
messageType : 'std_msgs/String'
});
