runNode(cls, runcfg)
Class Method

source code

Start the node with given name from the given configuration.

Parameters:

runcfg (AdvRunCfg) - the configuration containing the start parameter

Raises:

StartException - if the screen is not available on host.
Exception - on errors while resolving host

See Also: node_manager_fkie.is_local()

runNodeWithoutConfig(cls, host, package, binary, name, args=`[]`, masteruri=None, auto_pw_request=False, user=None, pw=None)
Class Method

source code

Start a node with using a launch configuration.

Parameters:

host (str) - the host or ip to run the node
package (str) - the ROS package containing the binary
binary (str) - the binary of the node to execute
name (str) - the ROS name of the node (with name space)
args ([str, ...]) - the list with arguments passed to the binary
auto_pw_request (bool) - opens question dialog directly, use True only if the method is called from the main GUI thread

Raises:

Exception - on errors while resolving host

See Also: node_manager_fkie.is_local()

callService(self, service_uri, service, service_type, service_args=`[]`)

source code

Calls the service and return the response. To call the service the ServiceProxy can't be used, because it uses environment variables to determine the URI of the running service. In our case this service can be running using another ROS master. The changes on the environment variables is not thread safe. So the source code of the rospy.SerivceProxy (tcpros_service.py) was modified.

Parameters:
