(1) "the bumper should be at the height of the red Technic beam in this figure" Does this mean that a the design must use a studded beam? (A stud-less beam is not as "tall" as the beam in the image.) (2) "The bumper must be straight and not angled (...) (19 years ago, 17-Jun-07, to lugnet.robotics)

(...) That appears to be a typo. The track fits on a FLL table, so it's a 44"x92" inch oval. And the lane is about 2ft wide. It's pretty easy to build and program a robot for this event. It just needs to follow a specific shade (actual value will (...) (19 years ago, 17-Jun-07, to lugnet.events.brickworld, lugnet.robotics)

(...) Seems clear to me :) there will be magic.... Actually - looks like a really wacky typo. Hopefully Steve H or Brian D jumps in to clarify for certain. But, I believe the full track layout is 4' x 8'. So, the track itself is just under 2' wide. (...) (19 years ago, 17-Jun-07, to lugnet.events.brickworld, lugnet.robotics)

(...) Okay, I'm confused. How can an 8' x 10' track be centered on a 4' by 8' surface? What is the actual width of the track? If the whole track fits on a 4' x 8' surface, then I would assume the width must be less then 2'. Gus (19 years ago, 17-Jun-07, to lugnet.events.brickworld, lugnet.robotics)

(...) Yes, that should be the latest version. (...) That is correct. You shouldn't need to do anything else. At one point, I made some changes to the firmware so the program could also access the run button. But, normally all that is handled in the (...)

(...) I'm using what appears to be called BrickOS 0.9.0. It was installed using John Hansen's simplified installation from his BricxCC sourceforge site.

(...) Gus, It sounds like the code is testing for pressing the run button, but not pressing the power button. I would think testing for shutdown would be good enough, but who knows... :) What version of BrickOS are you using? I'd be glad to take a (...) (19 years ago, 17-Jun-07, to lugnet.robotics.rcx.legos)

I have a big and somewhat complicated BrickOS program that I believe is reasonably well behaved. All my loops monitor shutdown_requested and I have tested stopping the program with the Run button while the program is in various states and it always (...)
