(...) This just was an forgotten bug that with older Robolab versions didn't harm. The solution is to remove the "Value of red container" and replace it by a blue container constant list ("User3") while selecting "RED". -Claude (19 years ago, 15-Aug-05, to lugnet.robotics.rcx.robolab)

Yes, that requires the RCX to receive. What I am looking for is a function which is much like the "is RCX in view" in the direct mode. This function allows the IR tower to detect any RCX in range, even the RCX is in in idle state, but just on, .... (...) (19 years ago, 10-Aug-05, to lugnet.robotics.rcx, lugnet.robotics.rcx.robolab)

Hi I understand that Robolab has a feature to detect if the RCX is in view thru the direct mode. However, this only means it has to face toward the IR tower which connected to the PC. Then, how about the way a RCX's capability to detect the whether (...) (19 years ago, 9-Aug-05, to lugnet.robotics.rcx, lugnet.robotics.rcx.robolab)

Orient both RCXs so that they are pointing towards the ceiling. Set the RCX transmit power level to high (default is probably low power); there's probably some Lejos function to do this -- all it requires is setting one bit in an I/O register to 1. (...)
