Nxt Compass Sensor Tutorial

The compass sensor connects to an nxt sensor port using a standard nxt wire and uses the digital i2c communications protocol.

Nxt compass sensor tutorial.

The compass sensor is housed in a standard mindstorms sensor housing to match the other mindstorms elements. Program using labview lego. In the picture to the left you can see the compass sensor is mounted high well above both the motors and computer brick. The compasspilot is an extension of the differentialpilot class.

A brief introduction tutorial part 2 duration. 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. To use the compass sensor from nxt g an additional piece of software needs to have been added to your computer. The essentials are things every nxt programmer should know.

The nxt sensor ports support three different types of sensor. I think this is a limit of the nxt g interface not the sensor itself. Using nxt components with a micro controller. Some of these movies have exercises directly under them.

Programming the nxt compass sensor to point in the right direction. It s important to do these exercises not just assume you get it the advanced section is for reference purposes. This tutorial for lego mindstorms nxt is divided in two sections. The current heading is calculated to the nearest 1 and refreshed 100 times per second.

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. Using hitech compass sensor. 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. But if you are using a port splitter or a remote nxt or rcx it may be of interest.

At brickfest there was a wonderful demo of the compass sensors. The nxt compass sensor contains a digital magnetic compass that measures the earth s magnetic field and calculates a heading angle.

The current heading is calculated to the nearest 1 and refreshed 100 times per second. Using the hitechnic compass sensor with nxt g. It needs a hitechnic or mindsensors compass sensor plugged in to one of the sensor ports.
