| | Kalman Filter on the NXT
|
|
The Kalman Filter may be perceived as a discouraging, almost occult calculation method. Many do apply the filter just by following some "cooking recipes", and they don't care much about the internals. However, if the filter is well studied and (...) (12 years ago, 28-Dec-12, to lugnet.robotics)

I have a memory from attempting to use the Kalman filter, starting with a model, and working through the math, that it made some assumptions, which importantly included an originally good sensor signal subsequently clouded by noise. Kalman can (...) (12 years ago, 28-Dec-12, to lugnet.robotics)

(...) That's what the Kalman filter is about. One of its important application areas is navigation (from rockets to ships and robots). In our example, we try to develop the implementation for a robot driving in one only dimension, the x-axis. And (...) (12 years ago, 29-Dec-12, to lugnet.robotics)

Also I got an interesting reply from lego. I asked them why all of their motors were slow. I MOC'ed a 8090 Supercar together with a 30,000 rpm 7.2 Hobby RC motor. Great in theory… reality not so much. I got it to move quickly and I spun a tire off (...) (11 years ago, 9-Sep-13, to lugnet.robotics)

Glad the EV3 software download is free. It would definitely support the students working on their programs outside of the lab. Of course, in many of the Title I schools, many have no access to home computers. It's going to be interesting how younger (...) (11 years ago, 11-Sep-13, to lugnet.robotics)
