Since the us sensor block returns only a single byte the sensor returns the heading angle divided by two currently.
Nxt compass sensor tutorial.
Using nxt components with a micro controller.
Using hitech compass sensor.
A brief introduction tutorial part 2 duration.
The compasspilot is an extension of the differentialpilot class.
It needs a hitechnic or mindsensors compass sensor plugged in to one of the sensor ports.
Using the hitechnic compass sensor with nxt g.
To use the compass sensor from nxt g an additional piece of software needs to have been added to your computer.
Program using labview lego.
But if you are using a port splitter or a remote nxt or rcx it may be of interest.
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.
Put a compass equiped ro bot on a turntable and spin the turntable.
The compass sensor connects to an nxt sensor port using a standard nxt wire and uses the digital i2c communications protocol.
This tutorial for lego mindstorms nxt is divided in two sections.
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.
The current heading is calculated to the nearest 1 and refreshed 100 times per second.
The nxt sensor ports support three different types of sensor.
In the picture to the left you can see the compass sensor is mounted high well above both the motors and computer brick.
Programming the nxt compass sensor to point in the right direction.
The essentials are things every nxt programmer should know.
This is a guide to using the motors and sensors from the lego nxt set with a parallax basic stamp ii or bs2.
It s important to do these exercises not just assume you get it the advanced section is for reference purposes.
The compass sensor connects to an nxt sensor port using a standard nxt wire and uses the digital i2c communications protocol.
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.
The compass sensor is housed in a standard mindstorms sensor housing to match the other mindstorms elements.
At brickfest there was a wonderful demo of the compass sensors.
