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...
View ArticleVoting 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...
View ArticleLight 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...
View ArticleMeasuring the temperature of water
Use a temperature sensor, to measure the temperature of 3 different water sources. Gather data points every second for 25 seconds from each sample for analysis.
View ArticleSound 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...
View ArticleFind 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...

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....
View ArticleJumboBooks: An introduction to using microprocessors in LabVIEW
The Center for Engineering Education and Outreach at Tufts University has created JumboBooks, a set of educational tutorials to program different devices in LabVIEW. The microprocessors used include...
View ArticleInside a two-step simple line follower
In this unit, we will use the datalogging tools available in the EV3 Software to study the internal operation of a two-step simple line follower with one Light sensor. It is a very simple but powerful...
View ArticleGPS accuracy testing with LEGO bricks
Unlike normal GPS units, commonly found in smartphones or your car, that are accurate to roughly three meters, differential GPS uses two GPS receivers to get a reported accuracy of three centimeters!...
View ArticleLight and Dark Scavenger Hunt
This challenge provides a basic introduction to datalogging with EV3. Datalogging enables you to collect data from one or more sensors connected to the EV3 brick over a period of time. It is possible...
View ArticleHow to export an EV3 data file (*.rdf) to Excel
To open an EV3 data file (*.rdf) in Excel (or equivalent application), the trick is to convert it to a (*.csv) file using the the Tools > Export Datasets menu option in the EV3 Software. If you need...
