 | | lejos program terminating immediately

Hi, I'm trying to use leJOS to display the current value of the rotation sensor I have hooked up to Sensor Port 1, but when I run the program, the RCX just beeps and ends the program immediately. Here's my code: import josx.platform.rcx.*; public (...) (19 years ago, 10-Aug-05, to lugnet.robotics.rcx.java)

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)

(...) Not sure what you mean here. You could certainly program some RCX's to "ping" each other to determine if they are in mutual IR range. RCX-A sends out a message & listens for a reply, while any other RCX that "sees" such a message immediately (...) (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)

Hello all. The mirror trick works for sending the signals from the IR tower to the RCX (I'm only using a single RCX). However, the return signal the RCX wants to send to the tower isn't transmitted across the mirror. Since you mentioned leJOS and (...) (19 years ago, 8-Aug-05, to lugnet.robotics.rcx)

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. (...)

Greetings helpful companions. Now that I've buttered you up, let's move on... I've built a robotic arm using my RCX 1.0 brick. I'm controlling it via my computer with LeJOS (not important, I think).
