(...) Here's my fantasy: implementing prototypical ATC (Automatic Train Control) signalling with sensors (e.g. counting coupler magnets, as the best functional equivalent to axle counters) at block boundaries to detect block occupancy, and IR (...)

Hey robo folks, Abstract: I want to run Python on the NXT, not on my PC and connect to the NXC remotely. Did I understand the architecture correctly? Any hints on translation? As far as I know, the NXT is so far lacking support for high-level (...) (17 years ago, 9-Feb-08, to lugnet.robotics)

(...) Dick Swan's replacement RCX firmware also does not support directly manipulating the IR led and it doesn't support microsecond timing control. Both of these features would be required in order to send the IR messages to a Power Function or R/C (...) (17 years ago, 4-Feb-08, to lugnet.general, lugnet.technic, lugnet.trains, lugnet.robotics)

(...) I doubt that's possible - a bytecode program just can't run fast enough to do the timing for the IR commands, on either brick. The NXT can only manage it because it sends them over a slow comms link to a HiTechnic IRLink sensor, then that (...)
