I totally forgot to post the video I made of the IMU sensor.
This clips shows how accurate the IMU sensor can be. This IMU sensor combines a 3 axis gyro and a 3 axis accelerometer. The signals from both sensors are combined using a nonlinear complementary filter to get an output signal that has low noise and is drift free. (Well actually it is only drift free over 2 axis. It still drifts over the Z-axis.) This home made sensor will show a blue light when it is horizontal using a 0.5 degrees margin. Otherwise the light will turn red. The full color LED is a BlinkM.
You’ll find more about this sensor in my previous posts.
That’s excellent work!
Hi!
I’m really impressed by your job, do you have the schematic in order to reproduce your sensor? How do you interface the sparkfun with the NXT?
Good Job!
I do have a schematic and can send it to you later. But I advise you to look at the cruizcore sensor first. In 2d environments this does the same job as my sensor.
The cruizcore is only in 2D and i want a 3D sensor… your sensor seems to be perfect to do some experiment.
I’ll write a post with instructions.
