In this section, you will learn what the robotic systems are composed of, followed by their operation. Like we defined in the previous section, robotic systems are very similar to physical computing systems, just that in some physical computing systems, you might not have actuators that perform tasks that reduce human effort, unlike robotic systems. So, the elements of the systems as well as their operation are almost similar. In some cases, the term "physical computing systems" can be synonymous with robotic systems as well.

Just like any physical computing system, any robotic system will also have input sensors and output actuators connected to a CPU with input/output ports. The actuators are driven based on the computer program running on the CPU, which depends on the inputs from the sensors present in the robotic system.

To make it easy for you to understand as well as to give you a brief idea about the robot we will be building in the...
