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.

More info about Cinderella at http://cinderella.de, contact: kortenkamp@cinderella.de. Recorded at the University of Education Schwäbisch Gmünd, Germany."

leJOS NXJ alpha 0.2

Little late on this one, but the hard working guys over at leJOS have released the leJOS NXJ alpha 0.2.0 build. In case you are not familiar with leJOS, it is an advanced Java programming system for the NXT or RCX. This newest version of leJOS offers Bluetooth, Ultrasonic sesnor, and sound support. Please keep in mind that it is a work in progress, but you can grab it from the download page.

Quoted from the leJOS Website

leJOS NXJ Alpha 0.2 is now available. This release contains preliminary Bluetooth support, I2C support (Ultrasonic sensor), and sound support. There is no menu system yet so you still only get one run per upload
