Levels C and D are the final two of four levels in the Intro to Robotics series. Intro to Robotics is designed to start at the very beginning and systematically teach students electronics, programming, and then how to combine those skills to build a functional robot.

Along the way they will learn how to use common electrical components, read schematics, troubleshoot, and craft every line of computer code.

Please note, student must complete Levels A and B prior to moving on to Levels C and D. They will need both the skills and equipment from Levels A and B to complete the projects in Levels C and D.


Important Information for Virtual Classes:

Please note, classroom and student licensing is intended for in-person use. While our program can be used for virtual classes, the purchaser of the curriculum is required to maintain control of the curriculum files and is liable for curriculum distribution outside the licensing agreement. Instructors are not allowed to distribute curriculum files to students in a manner that would allow students to distribute the files to others.

If your class model requires students to have a copy of the curriculum files and control of the files cannot be maintained via a secure system, each family should purchase a home kit instead. This will allow each family to have their own watermarked copy of the curriculum files. Home kits can be found here.


Ordering Information

Please note, all components are ready to use. Any soldering or other critical modifications have been made to each piece of equipment to ensure a student can use the component without issues. Please contact us if replacement components are needed. Part compatibility or required prep work (soldering, etc.) is a potential issue when purchasing components from other sources.

For each component kit purchased, you will also need the following items (not included):

  • A Desktop Computer, Laptop, or Chromebook
  • Anti-Static Mat
    • Highly recommended to prevent damage to more sensitive equipment such as the Raspberry Pi camera; click here to find one at a bargain price. This is particularly needed in Level C.
  • AA Batteries x6
    • These will power the robot, we recommend rechargeable batteries, click here to learn more
  • 9v Battery
  • USB Drive
    • Minimum 4gb
  • Electrical Tape
    • Used to build a track on the floor for the robot to follow; use black electrical tape if you have light colored flooring, use white electrical tape if you have dark colored flooring
  • USB to SD Card Adapter (optional)
    • Optional activity in Lesson D-1 shows students how to back up their SD card to their computer, click here to see links to adapters

Besides the items above, you’ll need the same items you have on hand from working through Levels A - B:

  • Level A and B Curriculum and Component Kits
  • Computer Monitor
    • A television can also be used provided it has HDMI inputs
    • Please note, a laptop computer or Chromebook will not work for this purpose
  • HDMI cable
    • Likely attached to your computer monitor
  • AA Batteries x2
  • Keyboard and Mouse
    • Please use a wired keyboard and mouse if possible. Wireless models do not work reliably with the Raspberry Pi. Visit the Level A Resource List for a list of inexpensive keyboard and mouse options.
  • Internet access (wired or wireless)
    • For this level of the course, internet access is required to download libraries and modules.

Please note, none of the equipment needs to be exclusive to the Raspberry Pi. Students may be able to use monitors, keyboards, and mice currently in the computer lab. Double check for the proper inputs and cables.

Levels C & D FAQ

Q. What age is this curriculum appropriate for?

A. We've designed Levels C and D to be used by high school students. We do not recommend Levels C and D for middle school students in a classroom setting unless the students are academically gifted and working with a low student to teacher ratio.


Q. How will I receive my order?

A. The PDF files containing the curriculum can be downloaded following purchase. Printed copies of the curriculum are not available. The component kits will be shipped to you.

If ordering via PO, please include the email address for the classroom teacher so a download account can be set up at the time the order is placed.


Q. How many lessons are in Levels C & D and how long does each lesson take?

A. There are 18 lessons in each level. Each lesson will take 2-3 hours to complete. If students are meeting five days a week, Levels C and D can be completed in a semester. If students only meet 2-3 days a week, we would recommend planning a full academic year to complete both levels.

Q. What if we have a question or run into a problem?

A. We are here to help! Click here to contact us and we will help you get back on the right track.

Also, please head on over to Facebook and join the 42 Electronics User Group. It's a great place for current or perspective users to ask questions, get project ideas, and connect with others using the Intro to Robotics program.



Q. Are the component kits reusable for the next group of students I teach?

A. With proper care, most of the components are non-consumable. In reality some of the more fragile parts (LEDs, resistors, etc.) may need to be replaced fairly regularly but those particular components are inexpensive to replace. Contact us for information on replacement parts so we can help ensure compatibility and help you find a bulk solution if you are teaching large numbers of students. 

For Level D, once the chassis, wheels, and motor mounts are assembled, we recommend not attempting to disassemble those physical pieces as they really aren't meant for regular disassembly. However, the other components can be added and removed from the robot as needed to complete not only the course but also additional projects later. For subsequent years of students, please contact us and we can walk you through which pieces likely won't be reusable for the next group.

Please note, as student progress into Levels C and D, the circuits get quite complex and projects build over several lessons. So unlike Levels A and B, it's not feasible to disassemble projects at the end of each class session so kits can be shared between sections of a course. Please plan on a component kit for each team of students.
