Nxt Compass Sensor Tutorial

If you are using a sensor connected directly to a nxt sensor port you can use the sensorport class and you can probably skip this section.

Nxt compass sensor tutorial.

The current heading is calculated to the nearest 1 and refreshed 100 times per second. In the picture to the left you can see the compass sensor is mounted high well above both the motors and computer brick. A brief introduction tutorial part 2 duration. Some of these movies have exercises directly under them.

It s important to do these exercises not just assume you get it the advanced section is for reference purposes. The compass sensor is housed in a standard mindstorms sensor housing to match the other mindstorms elements. Using nxt components with a micro controller. Programming the nxt compass sensor to point in the right direction.

But if you are using a port splitter or a remote nxt or rcx it may be of interest. The nxt sensor ports support three different types of sensor. Since the us sensor block returns only a single byte the sensor returns the heading angle divided by two currently. The compasspilot is an extension of the differentialpilot class.

At brickfest there was a wonderful demo of the compass sensors. I think this is a limit of the nxt g interface not the sensor itself. However rather than just providing schematics and sample code for the bs2 i ll be providing some theory on how the sensors work as well. The current heading is calculated to the nearest 1 and refreshed 100 times per second.

This tutorial for lego mindstorms nxt is divided in two sections. Chad cardwell 414 242 views. Put a compass equiped ro bot on a turntable and spin the turntable. To use the compass sensor from nxt g an additional piece of software needs to have been added to your computer.

The nxt compass sensor contains a digital magnetic compass that measures the earth s magnetic field and calculates a heading angle. Using hitech compass sensor. The compass sensor connects to an nxt sensor port using a standard nxt wire and uses the digital i2c communications protocol. The essentials are things every nxt programmer should know.

Using the hitechnic compass sensor with nxt g. This is a guide to using the motors and sensors from the lego nxt set with a parallax basic stamp ii or bs2. It implements the same methods but uses a compass sensor to ensure that the pilot does not deviate from the correct angle of robot heading.
