Chapter 5: Getting into Gear – My First Geared Robot

A wheel with teeth on it is called a gear. A gear is used for various applications, including the following:

  • Changing the speed of an object
  • Changing the direction of the force that's being applied
  • Changing the torque of an object

Whether it is your parents' car or their bike, vehicles use gears to move. Gears are used in almost all machines, mechanisms, and robots. You can find at least one application of gears in your printer, machine tools such as drills, industrial robots, packaging machines, and so on. The most common example of where you can find gears is in the wall clock in your home! The hours, minutes, and seconds hands are all interconnected with the help of complex gear mechanisms.

In this chapter, you will learn about various concepts surrounding gears, such as gear ratios and torque, by performing some useful hands-on experiments. We will be covering the following topics:
