Nxt Compass Sensor Tutorial

Using nxt components with a micro controller.

Nxt compass sensor tutorial.

Program using labview lego. 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 hitech compass sensor.

A brief introduction tutorial part 2 duration. This is a guide to using the motors and sensors from the lego nxt set with a parallax basic stamp ii or bs2. Using the hitechnic compass sensor with nxt g. It needs a hitechnic or mindsensors compass sensor plugged in to one of the sensor ports.

The compass sensor is housed in a standard mindstorms sensor housing to match the other mindstorms elements. Chad cardwell 414 242 views. Since the us sensor block returns only a single byte the sensor returns the heading angle divided by two currently. The current heading is calculated to the nearest 1 and refreshed 100 times per second.

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. 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. I think this is a limit of the nxt g interface not the sensor itself.

The current heading is calculated to the nearest 1 and refreshed 100 times per second. Put a compass equiped ro bot on a turntable and spin the turntable. But if you are using a port splitter or a remote nxt or rcx it may be of interest. In the picture to the left you can see the compass sensor is mounted high well above both the motors and computer brick.

The compass sensor connects to an nxt sensor port using a standard nxt wire and uses the digital i2c communications protocol. Programming the nxt compass sensor to point in the right direction. Some of these movies have exercises directly under them. The compasspilot is an extension of the differentialpilot class.

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 nxt compass sensor contains a digital magnetic compass that measures the earth s magnetic field and calculates a heading angle. 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.
