I got my son a Lego Train set for Xmas - and have been trying to figure out how to build a Mindstorms robot to run on Lego train track. * The Train motor isn't much use since it picks it's power (and hence speed and direction) from the track. * The (...)

(...) This is a recurring topic in .trains and the consensus seems to be that a mobile RCX brick requires either that it is battery powered (not great for battery life), or that you do surgery on the motor.

In that case just put *no* power on the rails (that is, run on some track not connected to any power) and feed one of the (...) (23 years ago, 27-Dec-01, to lugnet.robotics, lugnet.trains)
