Things that go bump

Design and construct a car and program it to travel in a straight line until it hits a wall. Once it hits the wall, program the car to reverse direction and continue until it hits another wall at which point it stops.   Tip: What sensors can be used to detect collisions between objects? Resources […]

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 plan: Voting Booth – RCX […]

Just like its little red counterpart, the Etch-A-Sketch®, the NXT-A-Sketch lets you turn two knobs to draw your picture. However, rather than using a stylus and aluminum powder, the LEGO NXT model is entirely digital, making use of the Servo motors and the LCD display. Building To build the NXT-A-Sketch, two motors are attached to […]

Survival of the fittest: NXT style

A group of Tufts University students stand around a squared-off area of linoleum cheering fervently. They scream things like “Go Moosie!” and “Your buzzard’s knocking my penguin!” The whole scene seemed somewhat out of place; after all, this was an engineering lab. It all makes sense when you realize that Moosie, Buzzard,  and Penguin are […]

Motor vs Move – Part II: Action

In Part I of Motor vs. Move, we looked at how the Move block incorporates a control algorithm to help robots move more accurately. What else is different between the Motor and Move block in NXT-G? Motor The Motor block has an “Action” panel which includes a drop-down menu pertaining to how the robot’s motor […]

Motor vs Move – Part I: The Control Algorithm

If you are programming a robot with NXT-G, you may be wondering what’s the difference between the Motor and Move blocks? The answer to this question has a significant impact on how your robot will move. The LEGO MINDSTORMS Education NXT software (NXT-G) includes these two blocks for motor control. While the Motor and Move […]
