The Embedded World exhibition and conference, the world’s most important event for the embedded community, will take place from March 3 to 5 in Nuremberg, Germany. Come and visit us at the booth of our partner Atlantik Elektronik (booth 12-443) to see a cool technology demo involving the POCO Platform, a Lego Mindstorms® robot, Digi hardware and an iPhone™.
A preview of the demo can be seen in the video below.
How does it work? The Mindstorms vehicle is remote controlled using the iPhone’s accelerometer. The iPhone talks to a Digi ConnectCore Wi-9C running Linux and a POCO-based application over a WiFi connection. Connected to the Digi board is a Serial-to-Bluetooth™ dongle from Ezurio. We have a small application running on the iPhone that sends accelerometer data to the server process on the Digi board over UDP. The server application then sends command to the Lego NXT over Bluetooth. The Mindstorms vehicle is equipped with sonar, sound and light sensors, and the sensor data is sent back to the POCO application, which has a builtin web server to visualize the data on an Ajax-based web page. The NXT is running nxtOSEK, which allows us to program it in C and even C++. The program running on the NXT is a modified version of the nxtgt sample application that ships with nxtOSEK.
The video was filmed on November 8, 2008 at the “Lange Nacht der Forschung” in Klagenfurt, Austria, where this demo was a favorite among children of all ages.
