dIMU Physics Experiment


Thanks to Marcelino Andrade who sent us a video and explanation of some physics demonstrations he’s doing for his students with the dIMU for LEGO MINDSTORMS NXT.

Marcelino, of Universidade de Brasilia sent us a video of his project below.

Marcelino writes:

I’ve bought sensors to teach my students and introduce some concepts about IMU. I am used in a real experiments and didactic demonstrations (video:  Accelerometer /Bluetooth/Matlab) . . . The calibration method uses gravity in six orthogonal positions (Matlab code and n<100) . . . I’ve done some experience with Kalman filtering for sensor fusion (accel and gyro) and the result was more stable (graphic).

Marcelino has also sent us the Matlab and NXC code for his experiment, which can be downloaded here: http://www.dexterindustries.com/files/Andrade_Code.zip

We would love to share your projects with other folks that read our blog.  Please feel free to contact us about them!
