One is the diplay/CPU (A). The other is the power sources (B). B plugs into A, (...) (18 years ago, 8-Jan-06, to lugnet.robotics)

I don't know how much the new motors pull, but the "old" motors took 250mA @ 9V under load. According to the USB specs, the port should provide 500mA @ (...)

It has the right size for a little coaxial power plug like the one used for the 9V trains. All it (...) (18 years ago, 10-Jan-06, to lugnet.robotics)

| | | | | | | | NXT question: port allocation —dan miller

| | | | | | Question for the in-the-know crowd -- does the NXT have 3 motor ports and 4 sensor ports, or 7 general-purpose ports? IOW, could you connect 4 motors and only 3 sensors? (18 years ago, 11-Jan-06, to lugnet.robotics)
