[pbenco]

Hello
Perhaps can you link to another sourceforge project (I'm not owning it, but i find it interesting): http://sourceforge.net/projects/libnxter/

Libnxter is a collection of robot utilities for lego mindstorms nxt robotics kit, written in NXC language, and currently implements: two wheel drive vehicle, odometer, motor control, sonar, integer matrix algebra, vectors, PID control and kalman filter.

Some informations can be retrieve here : http://naba.blogspot.com/search/label/nxt

Yeah, I've seen that before, when I was doing my odometry thing. Pretty cool.

can you pls explain what your highpass and your lowpass filter do?
I know both terms only from analog frequency filters (e.g. for Low-frequency or high-frequency filters of loudspeakers)

Hello doc-helmut

As far as i understand this part of the library (once again, i'm not the owner/coder, just someone saying it seems interesting ) this is a test code (FiltersTest.nxc ) to use an "adjustable rate" sampler (in sampler.nxc) with the light sensor, to test low and high pass filters actions. It has no relations to the kalman filter used for odometry, or the vehicle "object", which embed all the code for two wheeled navigation
