Hi We just started using RCX and Robolab for a university course in cognitive systems. Our first lab was to navigate a maze using no sensors (internal representation only). The worst problem is inconsistent results given consistent power to the (...) (22 years ago, 3-Oct-04, to lugnet.robotics.rcx.robolab, FTX)

What is the best way of waiting for more than one type of event? I want to turn on a motor and run it for 5 seconds or until the tough sensor is pressed, whichever comes first. This seems like such a basic problem that I'm quite sure there must be a (...) (22 years ago, 29-Aug-04, to lugnet.robotics.rcx.robolab)

I suspect that the 0 means "the event register". The designation is sure confusing. To (...) (22 years ago, 27-Aug-04, to lugnet.robotics.rcx.robolab)

(...) Your approach is pretty common. As it turns out, you can (should) remove the wait time, also. Many people think they need to tell the robot how long to turn, or how long to go forward.
