Bluetooth Gravity Controlled Robot

Check out this cool find over at the nxtasy blog.

Ulli Kortenkamp has used bluetooth technology along with an Apple Macbook's internal gravity sensors to create a gravity controlled robot.



Ulli Writes on the You Tube page:

"In this video we show how to use the gravity sensor of a Apple MacBook Pro in order to remote control a LEGO MINDSTORMS NXT robot. They connect via bluetooth, and the Interactive Geometry Software Cinderella.2 is used as controlling software. It reads the data from the gravity sensor of the MacBook, processes it and then controls the motors of the NXT robot accordingly.

Mindstorms Cellular Bluetooth NXT Control

With the addition of the bluetooth technology in the Mindstorms NXT system a whole new area of control was opened. The guys over at LEGO have introduced bluetooth support for the Mindstorms NXT system in the area of bluetooth enabled cell phones.

Recently, LEGO has made available their NXT Mobile Application that allows you to control your robot wirelessly via bluetooth technology. According to their specifications the following cell phones are supported:

• Nokia: 6680, 3230
• Sony Ericson: W800i, W550i, K610i, K800i, K750i, Z710i, Z550i, K510i
• BenQ-Siemens: CX75, X75

With the software provided by LEGO, you can control your robot in two different modes: remote control and program control. In the remote control setting you can direct and drive your robot with a joystick/command wheel. On the other hand, in program control, you can select what program you want the NXT to run and then use the numbers to send the NXT messages during the program.

It's amazing to see what LEGO has done with bluetooth in the NXT system. With such great innovations already, I'm excited to see what the future holds for bluetooth and the NXT!
