Scribble Bots

Instructions (Part I): Reflect on places where circuits exist in your daily life. Hypothesize at least 5 and share them with your a classmate. After sharing your circuit applications, carefully view the below video to obtain a more in-depth understanding of electricity and circuits. 

Instructions (Part II): Now that you have a basic understanding of electricity and circuits, it’s time to apply your knowledge to create circuit that spins a motor to create unbalanced net force, causing a “robot” to scribble a pattern on a sheet of paper. This robot is called a “Scribbling Robot”. Watch the video below for an example of how a similar Scribbling Robot performs its task! Click here for another example of a Scribbling Robot in motion.

Instructions (Part III): Using your materials and the images found here as a guide, create your Scribbling Robot. When done, secure a large piece of white paper to the ground, and let your Robot create its own unique pattern! 


 Additional Challenges:

  • Try to create a perfect circle with your Scribble Bot

  • Change the position of the markers, motor, or batteries to see what changes occur 

  • Tie together multiple Scribble Bots and experiment

Instructions (Part VI):

 Once successful, take a clear picture of your robot’s pattern, similar to the one shown here, and upload it below. Type your first name in the “Subject” area. A QR code is provided for ease of upload.
