I wanted to draw a live map showing the progress of the Lego Street View car as it drove outside. The dGPS sensor does a great job of plotting the car’s location, and the NXTBee provides a perfect high-speed long-distance serial link back to my Mac at home base. But how to display a live map that is updated with the car’s location in real-time? What platform should I use to develop a user-interface to the control the car and to plot map data?
When I was developing the Lego Street View Car I realised that I needed a way to control the car more reliably than Bluetooth, and without relying on the existing of a wifi network. The NXTBee is the obvious choice. It uses the industry-standard XBee protocol giving high-speed serial transmission over a 300 ft range without any setup or the overhead of Bluetooth communication.
