The aim of this assignment is to learn the basics of creating ROS packages, editing knowledge in the KnowRob knowledge base, and querying the knowledge base from another program via the ROS communication middleware. The task is to create (1) an extension package to the KnowRob knowledge base that contains information about objects in a living room as well as a simple 'semantic map' describing the arrangement of objects in the room, and (2) a (very simple) chat client that accepts questions in natural English language and converts them into queries to the knowledge base.

Please install the system according to the instructions here: https://ai.uni-bremen.de/wiki/software/ros/installation

Before starting with the implementation, you should be familiar with ROS and the basic usage of the KnowRob knowledge base. The following tutorials will help you get into it:

• Getting started with ROS
• Getting started with KnowRob
• KnowRob basics
• KnowRob Beginner tutorials
• KnowRob Advanced tutorials 1--3
• Semantic Map editor
