Control NXT by MacBook gravity sensor
Saturday, June 30th, 2007
Here’s a YouTube showing how to control the NXT using 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.

Using Stepper Motors
Monday, June 18th, 2007
Steppers are motors that move in discrete steps. You can control them to move a given number of steps without any feedback. You can rotate them slowly but with a lot of force without using any gears.
See full description of the project (which includes a video) to learn how to integrate a common stepper motor into a NXT creation and how control it.
My controller was influenced by a stepper controller that Michael Gasperi posted to one of the forums. See the forum for the Michael’s circuit and program, and click here for a video of his stepper in action.

Challenge #2 Winners!
Wednesday, June 6th, 2007NXTasy.org challenge #2 is over, and it is time to declare the winners. Unfortunately, we had very little participation this time - only 2 contributions in the NXT-G category and 4 in the ‘other languages’ category. I pledge everyone to answer my short survey here so I decide about future challenges.
In the NXT-G category only Larry Menor completed the task fully, with an average outcome of 54 seconds. Larry - you win 60$ for purchasing in mindsensors.com!
In second place we have Alex Dimitrov. Alex has almost made it to first place, with average time of only 28 seconds, but his robot fails to put back the ball (well, he says it does work when he doesn’t video it…). I’ve given him some extra days to prove his claim - but he didn’t reply.. For the sake of good will - you earned the second place, and win $35 coupon at mindsensors.com.
The ‘other languages’ category had some more participants. Here the second place goes to Michail Zampetakis whose NBC programmed robot score 31 seconds on average. Michail - you won $35 courtesy of mindsensors.com. I want to thank the ‘not-winning’ users (cheer up guys - at the end, it’s all about having fun!) Laurens Valk (RobotC, 33sec and VERY close to 2nd place..) and Victor Potenciano (NXC, 85sec).
Finally - Hip-Hip-Hurry to Allen McArthur for a NXC programmed robot which complete the task with an average of 16sec! Great job, Allen! You earned your first prize 60$ reward big times!
I’m preparing a dedicated page with photos, videos and codes of all participants. Hopefully this will come up soon, but patience is a blessing…
