 ## Import Statements for Services and Messages
 ```python
-# TCP Endpoint package imports to enable ROS communication
-from tcp_endpoint.RosTCPServer import TCPServer
-from tcp_endpoint.RosPublisher import RosPublisher
-from tcp_endpoint.RosSubscriber import RosSubscriber
-from tcp_endpoint.RosService import RosService

 ```
 - The ROS node name
 
 ```python
-    tcp_server = TCPServer(ros_node_name)
+    tcp_server = TcpServer(ros_node_name)
