IoT is increasingly being used to teach students in the classroom for a number of subjects across science, math, and language. But research shows that while students enjoy learning with robots. The choice of the robot is usually dictated by the area of study and the age group of the student. Smaller robots or toolkits are particularly used to teach robotics or computer science. These toolkits can be physically manipulated allowing students to learn a variety of disciplines across engineering. However, the human-like shape of humanoids makes them easier to interact with, and for this reason, is often used for language lessons. In this book, the author has discussed fully functional Android device and its application.
