(...) Which it does pretty well, maxing out around 100 dB. (...) Not as much (yet!) as I'd like. The sound sensor has two modes familier to folks who work with dB noise levels. One is a "flat" frequency response curve, and one is a frequency (...) (19 years ago, 5-May-06, to lugnet.robotics)

The LEGO Education blog had some information a while ago on the NXT sound sensor. In addition to distinguishing decibel levels, they mentioned it featured "tone recognition". Can someone in the know comment on this feature. Can the sound sensor (...) (19 years ago, 5-May-06, to lugnet.robotics)

(...) What do you mean? It is possible to transfer files between a PC and the NXT over bluetooth so you can "stream" a .RSO file but doing so at 64 bytes per packet would be rather cumbersome. And playing the file on the NXT could not begin until (...) (19 years ago, 5-May-06, to lugnet.robotics)

(...) I can't figure out a easy way for me to test PC-to-NXT timelag, but I tried some simple bench tests on NXT-to-NXT. This is just the old standard of two timed loops (10,0000 interations), one empty, and one with a single block (or two), and (...) (19 years ago, 5-May-06, to lugnet.robotics)

I haven't seen any discussion on the performance of the bluetooth messaging. I've measured PC to NXT round trip (send message and receive acknowledgement) as typically being 30 milliseconds. Has anyon else done these measurements and were your (...) (19 years ago, 5-May-06, to lugnet.robotics)

We've all seen screenshots of the Labview programming environment that ships with the NXT. I'm curious about the interface on the actual NXT (with the standard firmware). How does the menu system work? Obviously there are size limits to how much (...) (19 years ago, 5-May-06, to lugnet.robotics)
