How could you build a device that uses sound to indicate the distance to the nearest object? For example, as an aid for a person with vision impairment. Other than using the Ultrasound Sensor, are there any other sensors that could be used to measure distance? Resources Echo Locator lesson plan – NXT-G (PDF)

Writing Efficient NXT-G Programs (PDF) describes how to make your NXT-G programs as efficient as possible to create complex behaviours with a minimum of memory. These techniques are particularly relevant for competitions such as FIRST LEGO League (FLL) and RoboCup Junior, in which competitors often download several complex programs onto a single NXT brick. The […]

Think of a way to design and construct the stubborn car: a car that will always return to its original place no matter how far it is rolled away from its starting point. Tip: How can you track the rotary motion of the car’s wheels? This challenge provides a great introduction to the idea of […]

The idea of this challenge is to have students set up several light sensors to log data over time. After the setup is complete, run the programs, turn off the lights in the room, and have the students leave. Walk around the room near the different sensors with a flashlight. After the data acquisition is […]

The idea of this radical challenge is to use the ultrasonic sensor, touch sensors, and buttons on the NXT to create a guitar. The ultrasonic sensor can control the pitch of the note based on the location of the user’s hand, and the touch sensors can control other parameters of the note created. Rock on, […]

The NXT Worksheet toolkit (ZIP) contains a set of images of the programming blocks used in the LEGO MINDSTORMS NXT Software (NXT-G). These can be used to create worksheets and instructions for students. Note: These are images of generic blocks, so they do not have unique features such as a motor or port indicator.
