Reading & Writing Electrical Diagrams

We are back at it with another lesson for the Engineering Design Club! This time we studied electrical circuits and diagrams in relation to robotics! This is a brief content summary of what we did in class.

Last session, we assembled Every Kid Gets a Robot and began learning about robotics and why it's important.

Every Kid Gets a Robot at Fisher Unitech for their Future of Manufacturing Teens Camp

Every Kid Gets a Robot is a robot that I designed to increase robotics educational accessibility for kids. Robotics education is important because its a hands-on way to teach a variety of STEM (Science, Technology, Engineering, Math) skills from electrical work to design to programming in a way that kids will remember.

The wheels and chassis are 3D printed, and the kids each have their own kit that we have worked on assembling. Today, we focused on wiring the robot. Next session, we will be learning more about programming the robot. The kids will be taking their own robot home at the end of the class!

Lesson Objectives:

  1. Understand what an electrical circuit is

  2. Learn how to read an electrical diagram (symbols, etc)

  3. Learn about the robot's components

  4. Finish assembling robot

  5. Begin to wire robot

In two groups, we covered electrical circuits and diagrams and the role that they play in robotics.

Group 1: Understanding Electrical Diagrams & Robot Electrical Components

This group was led by high school senior Dakshesh Daruri, president of FIRST Robotics Competition Team 4384 from International Academy East. He kindly shared his electrical knowledge with the students and showed them awesome YouTube videos to further exemplify the amazing world of electrical engineering.

Reading an Electrical Diagram

  1. Go over what a simple circuit is, see an example

  2. Talk about electrical safety (short-circuiting the battery, etc)

  3. Electrical diagram reading basics

Every Kid Gets a Robot Details

  1. Explain what the components of robot do and are

  2. Sketch how everything seems to be connected, and then see the real diagram and interpret it

Group 2: Every Kid Gets a Robot Assembly & Wiring

They finished assembling Every Kid Gets a Robot (or started if they missed the previous lesson). Then, using the two robot electrical diagrams, began the wiring process and learned how to make the connectors look better via braiding/twisting.


Want to teach your students more about electrical engineering at home? Check out these awesome resources. I suggest looking at Adafruit.com for their children's electrical kits as they have a wide variety.

Next week, we will tackle the programming via Arduino IDE and learn more about the robot and how it works.
