Hands-On Robotics with JavaScript

By: Kassandra Perch

Overview of this book

JavaScript has an effective set of frameworks and libraries that provide support for embedded device programming and the robotics ecosystem. You’ll be able to put your JavaScript knowledge to work with this practical robotics guide. The book starts by guiding you in setting up an environment to program robots with JavaScript and Rasberry Pi 3. You will build beginner-level projects, such as a line-following robot, and then upgrade your robotics skills with a series of projects that help you get to grips with the Johnny-Five library. As you progress, you’ll learn how you can improve your projects by enabling advanced hardware components and programming concepts. You’ll even build an advanced AI-enabled robot, connect its NodeBots to the internet, create a NodeBots Swarm, and explore Message Queuing Telemetry Transport (MQTT). By the end of this book, you will have enhanced your robot programming skills by building a range of simple to complex projects.

Chapter 8. The Animation Library

Servos are great tools for creating movement in our robotics projects but we need more control in order to create truly mobile walking robots. Each servo is different; for example, each servo moves at slightly different max speeds. If you want a bot to walk, you need timing control, and the ability to know when a servo has finished its movement. Enter the animation library; this powerful tool inside Johnny-Five allows you to fine-tune your servo movements to allow you more in-depth control.

The following topics will be covered in this chapter:

  • Animating movement
  • The terminology of the animation library
  • The construction of the animation object
  • Easing into your servo animations
  • Learning more about queuing and playing animation segments
  • Animation object events
