(...) TOTALLY agree. Not saying it's not relevant to robotics, there is lots of clever mechanical stuff to be learned from GBC... Just saying it's somewhat in a different direction from leaving a bunch of identical RCX based autonomous mobile (...) (19 years ago, 23-May-05, to lugnet.events.brickfest, lugnet.robotics.rcx)

(...) Not having an RCX does not necesarily make it irrelevant to robotics. I consider automatons fairly relevant - and the technique of getting a single motor to do many things is a very valuable one, especially considering the IO limitations of (...)

(...) Right, but haven't you and your cohorts (Hi Brian!) been busily proving that there hasn't yet been a mechanism that NEEDED an RCX? Most of the GBC modules are (brilliantly, elegantly...) purely mechanical except for the train ball return, and (...) (19 years ago, 23-May-05, to lugnet.events.brickfest, lugnet.robotics.rcx)

I've wondered about this for over a year now, but haven't brought it up because of not making it to the BF events. Now I can't stand it anymore and must ask. Have RCX owners considered pooling their units to run an event-long simulation? Each of us (...) (19 years ago, 21-May-05, to lugnet.events.brickfest, lugnet.robotics.rcx)

Hi I am a member of a project group at Aalborg University, Denmark, and the goal for our project on this semester is to code an operating system for the RCX brick from Lego. During a whole week, I have been strugling with the 8 bit timers of the (...) (19 years ago, 19-May-05, to lugnet.robotics.rcx)

It's not a true realtime interrupt. Some events may be recognized immediately (e.g. a new "mailbox" message, and some may be recognized on a 100 millisecond background scan (e.g. a "click" event). The event monitoring code does not put the task into (...) (19 years ago, 19-May-05, to lugnet.robotics.rcx.robolab, lugnet.robotics.rcx)
