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). What my issue arises is if my arm rotates, the IR (...) (19 years ago, 4-Aug-05, to lugnet.robotics.rcx)

This is cool! Thanks a bunch. In terms of feasibility and more sophisticated coding, I would perhaps think coding in NQC will be more desirable as far as teaching high school or college kid.

Hi I know how to put in a simple loop to, e.g., zero out an array of containers in inventor level 4. But, I found this on the net, it is nice and neat for loop - loops through 10 times to zero out 10 containers. All that was included inside a (...)

(...) This sounds to me like a good tactic. Your program might have some issue with turning in one direction vs another. (...)
