1. Why I like educational robots

    Why I like educational robots

    With all the available STEM options, we often get asked Why Robotics?  So here are some quick thoughts to kickstart your thirty second elevator speech for robotics program support. See what you think. I like educational robots because they make abstract concepts real. With this opening salvo, and depending on your primary expertise and...

  2. Find the hidden letter

    Find the hidden letter

    In this activity, use a robot equipped with a light sensor to determine the hidden letter message (under a table or in another room). The letter will be determined using light sensor collected data on 3 passes over of the letter.      Resources Find the Hidden Letter lesson plan...

  3. Sound display

    Sound display

    The idea of this challenge is to collect and display sound data from the NXT sound sensor in real time on the LCD display of the NXT. You could include the ability to pause data collection by bumping a button to “freeze” a particular screen of the data until another...

  4. Light sensor scavenger hunt

    Light sensor scavenger hunt

    How can you determine the light conditions in different parts of a room? Can you find light sensor readings in the range of 0-30? 60-90? 90-100? Can you draw conclusions and make generalizations about light intensity in the room?

  5. Voting booth

    Voting booth

    Think of an intelligent way to set up a “voting booth” to gather data, and plot this data on a graph for analysis.    Tip 1: What sensor can you implement for collecting this data? Touch sensor? IR sensor? Resources Lesson plan: Voting booth – NXT + ROBOLAB (PDF) Lesson...

  6. Pendulum mathematics

    Pendulum mathematics

    Pendulums are one of the earliest machines we see and Physics courses can take advantage of that familiarity to reveal fundamental principles and demonstrate the mathematical relationships. In this demonstration, I suspended an NXT with three sensors from above, and let it swing back and forth, recording the data via...
