DI dGPS

dGPS

• Sends GPS coordinates to your robot and calculates navigation information.  
• Powerful navigational calculators that can be used to navigate to target coordinates.
• Hooks directly into NXT sensor ports.
• Easy to Program in NXT-G, RobotC, NXC, and Lejos.

Detailed Description

Now your robots can know exactly where in the world they are! The Dexter Industries dGPS Sensor provides GPS coordinate information to your robot and calculates navigation information. The sensor provides latitude, longitude, time, speed and heading to your robot. It also has powerful navigational calculators that can be used to navigate to target coordinates. 

The Dexter Industries GPS Sensor can be used for any robot that needs to know where it is or where it’s going. You can do everything from track road trips on Google Maps to build a satellite-guided robot. 

The dGPS hooks directly into any of the four sensor ports on the NXT and can be programmed in NXT-G, RobotC, and Lejos.

Read GPS.zip

(zip)

The Read GPS NXT-G Block reads coordinate information like latitude, longitude, time, speed.

GPS Navigation.zip

(zip)

Performs navigation functions and allows the user to enter in destination coordinates and read back compass angle to destination and distance to destination.

GPS AOT.zip

(zip)

Calculates angle of travel between two points. Works like a compass.

NXT-G Example Programs:

Hello World.rbt.zip

(zip)

NXT-G program for getting started with the dGPS sensor in NXT-G. Reads coordinates and time and displays on the NXT.

Navigation.rbt.zip

(zip)

More advanced NXT-G program for navigating. This program calculates distance to destination and compass angle to destination from coordinates the user enters.

Geocaching to Einstein.rbt.zip

An example geocaching program like the one used in our blog post here.

Speed_trap.rbt.zip

(zip)

An example program in NXT-G that watches your speed for you. See the blogpost on it here.

RobotC Drivers and Examples:

RobotC drivers were graciously developed byXander.

dGPS Example

(.c)

A "Hello World" program for RobotC displays GPS coordinates.

Datalog to KML.c

(.c)

Short program that automatically logs where you are as you travel, and plots it on Google Earth. The program generates a txt file, you rename to a kml file, and opens in Google Earth.

Example_KML_File.kml

(kml)

An example Google Earth KML file.

NXC:

Examples For dGPS

(zip)

Two NXC examples for the NXT and the dGPS sensor. The first example is a quick and easy "Hello World" program (ex_digps.nxc) that shows UTC and coordinates. The second program demonstrates the navigational functions by taking a coordinate and then telling you how far you are from that coordinate and which direction it is in.  Special thanks to John Hansen for his work in helping us develop these. dGPS functions are now built into the NXC environment. You must use the latest releaseto use these functions.
