Hi, I was wondering if it is possible to use a electromagnetic device with the RCX and NXT. I tried with this one from a disk drive, and it worked quite well, but a few seconds after it start, the RCX shows the "low battery" icon. (The batteries are (...)

Hi Chris, (...) that is not quite right, there is an ATMEGA48 microcontroller insider the NXT Brick which generates the waveforms. It is connected to the main processor via an I2C-style interface. Besides that it also controls power to the NXT, (...) (19 years ago, 15-Jan-07, to lugnet.robotics.nxt)

(...) I am curious if you have tried measuring distance travelled simply by reading back the NXT motor encoder values? You would need to calibrate your 'bot so that you know the ratio of encoder units to centimeters or inches travelled (which would (...) (19 years ago, 15-Jan-07, to lugnet.robotics.nxt, FTX)
