Introducing The Lesson

Modified 2020-08-19 by Dev Ramesh


  • This will be a lesson for the student on the basics of Networking and Computer Terminals. It is important to comprehend networking to understand the basis of how computers connect with each other and to know computer terminal details to understand how computers can be controlled.
    • One robot can be made up of one or more computers that need to coordinate with each other, and robots may need to communicate with external systems; for these purposes, networking is essential.
  • (Optional) Networking should be applied to how the drone communicates with the basestation. To do this, teachers can start class with a small discussion instead of or in addition to the above hook. The following questions are potential discussion points:

What are some other robots or devices in your daily life that have to communicate with each other? How do you think they do this?

How will we control our drone? From what?

What features of the communication channel between our basestation and the drone could be important? Wireless connectivity, latency (delay between communications), throughput (maximum volume of communications)?

Main Lesson

Modified 2020-09-07 by Dev Ramesh

  • Teachers should cover the basics of the 7 layers of network abstraction and IP/MAC addresses as outlined in the student book.

  • Teachers define (and potentially demonstrate) what a computer terminal and shell is as outlined in the student book.

  • Teachers define SSH and what it is used for as outlined in the student book.

Ending The lesson

Exercise: Teachers should have students connect to the Pi via web browser and explain each of the components of the text editor.

Optional Exercise: Teachers can attempt to follow our old build instructions to connect to the drone over SSH; if you are able to, you can try to have students follow the similar process. These instructions are not too detailed and are outdated, so it may take additional troubleshooting on your end to figure this out (additionally this may not be compatible on chromebook).
