Mindstorms NXT remote controlled with G1 Android mobile phone

The application with instructions can be downloaded from http://sites.google.com/site/ghoelzl/nxtcontrol
This is my first application for the G1. It uses the pitch/roll sensor to determine the attitude of the phone. Via WLAN every 100ms the current information is sent to a Java application running on a PC. After calculating the speeds for the left and the right motor the application sends the information forward to the Mindstorm NXT robot via Bluetooth.
There is a new version at http://www.youtube.com/watch?v=A6IMh81geyA where you can directly control the robot via Bluetooth. Code and instructions can be found at http://sites.google.com/site/ghoelzl/nxtcontrolv2

I did what exactly you do. I have checked out your website. Just wanna know if you use lejos or icommand to send data to NXT from PC.

@vicmyc I used leJOS NXJ on the NXT robot

nice stuff! should it be possible to control the nxt directly by bluetooth?

[linuxgeocacher]

It should be possible with the new Android SDK 2.1. When the version will be officially available for the G1 I will work on it.

@amplivibe Now I adapted the application to Android 2.1, the NXT can be controlled directly via Bluetooth, see description of the video.

@linuxgeocacher - I like your Android WiFi/Bluetooth NXT demonstration anyway - ingenious :-)

[IAssemble]

@linuxgeocacher - actually the bluetooth support is available in SDK 1.6 I believe - I got it orking on an HTC Hero connected directly to an NXT - have fun!

[mdabdurrahman]

you are simply the besttttttttttttttttttt. Will get back to you once I install it on my HTC Dream

[linuxgeocacher]

Will try it under Android Version 2.1. Hopefully it will be coming to the G1 soon.
