Overview of this book

Artificial Vision and Language Processing for Robotics begins by discussing the theory behind robots. You'll compare different methods used to work with robots and explore computer vision, its algorithms, and limits. You'll then learn how to control the robot with natural language processing commands. You'll study Word2Vec and GloVe embedding techniques, non-numeric data, recurrent neural network (RNNs), and their advanced models. You'll create a simple Word2Vec model with Keras, as well as build a convolutional neural network (CNN) and improve it with data augmentation and transfer learning. You'll study the ROS and build a conversational agent to manage your robot. You'll also integrate your agent with the ROS and convert an image to text and text to speech. You'll learn to build an object recognition system using a video. By the end of this book, you'll have the skills you need to build a functional application that can integrate with a ROS to extract useful information about your environment.

ROS Commands


ROS doesn't have a graphical user interface to work with it; every action must be performed on the command line as it is compatible with Ubuntu. However, before getting your hands on the ROS, you need to learn about its most common commands. Here's a short list of them and their functionality:

  • roscore: This is the first command to be run when working with ROS. It enables the framework and provides support to any ROS program or operation. It should be launched in order to allow node communication.

  • roscd: This command switches to a stack or package directory without entering a physical path.

  • rosnode: These commands manage nodes and obtain information about them. Here, you can see the most used rosnode commands:

  • rosnode list: This command prints the information of active nodes.

  • rosnode info <node_name>: This informs the user about the entered node.

  • rosnode kill <node_name>: The function of this command is to stop a node process.

  • rosrun: Using this command, you can run any...
