Learning Robotics with ROBOTIS PLAY Systems

(By C.N. Thai)

Learning robotics with ROBOTIS PLAY systems

You can download excerpts from this book here and it is available as an eBook and as a paperback

This book contains 5 chapters:

1)  Chapter 1 presents foundational concepts regarding the system design approach used by ROBOTIS in creating its educational kits and the Sense-Think-Act paradigm used in developing the contents of this book.

2)  Chapter 2 describes the hardware characteristics of the PLAY700 kit and how to use the ROBOTIS MANAGER software tool using a “Basic Bot” design.

3)  Chapter 3 is a substantial chapter providing a gradual but in-depth tutorial about applications of the R+TASK and R+PLAY700 software tools using two robot designs - “Spinning Top” and “Car Bot”.  Topics included autonomous-behavior and remote-control algorithms, communication and multimedia programming techniques.  PC and Mobile uses of the TASK tool will be shown.

4)  Chapter 4 is also another substantial chapter mirroring the instructional approach and topics developed in Chapter 3 but now using the R+SCRATCH/SCRATCH 2 tool chain and its event programming features.

5)  Chapter 5 presents selected mechanical design concepts inherent in the mechanical components provided in the PLAY700 kit, with the goal of helping students understand the mechanical design concepts represented in the original example robots from various PLAY systems, and be creative in their own robot designs by showcasing modified or additional mechanical concepts and robot designs.

Chapters 2 through 5 also provide appropriate source codes and tutorial videos to illustrate the presented concepts, along with review questions to help students master learned materials.

You can access the YouTube playlist of all 67 video tutorials here.
