In the previous chapter, we have learned the basics of how to make sure that the robot is working under safe limits. In this chapter, we will be looking at how a robot can be made to do different activities at a click of a button, instead of typing the values one by one.

To do this, we will need to understand some advanced concepts of motion. Whenever you watch any video or play any video games, then you must have come across the term frames per second (FPS). If you haven't heard this term, then let me explain it for you. Every video made right now is actually made by still images. These still images are captured by cameras that click 25-30 times in a second. When these images are played back on the screen at the same rate at which they are captured, it forms a smooth video.

Similarly, in robots, we do have the concept of frames. These frames, however, are not images but instead multiple steps that the robot has to follow to achieve a specific motion. In a simple...
