 | | 8 power levels, and only 8?
|
|
Hi there, Inspired by the answer by Juergen Stuber in the lejos/legos thread, I suddenly began to think about the fact that "we" only have eight power levels to choose among. Why is that? And can it be changed? When programming my bot for the W3D, I (...) (25 years ago, 19-Sep-01, to lugnet.robotics.rcx.java)

(...) No, for example LNP and speedometer are missing, motor control is standard with 8 power levels. In general it uses the standard ROM routines much more than legos. On the good side the rotation sensor problems it had until two months ago are (...) (25 years ago, 19-Sep-01, to lugnet.robotics.rcx.legos, lugnet.robotics.rcx.java)

Amazon announced the publication of a new book: "Programming Lego Mindstorms With Java" by Brian Bagnall, Dario Laverde. Can anyone recommend it? Has anyone read a prepublication copy? Jerry (25 years ago, 18-Sep-01, to lugnet.robotics.rcx.java)

I ma using legOS and NQC, I also viewed lejOS, but I am not sure if lejOS can provide all functions of legOS provides, then does lejOS run in the same speed as legOS? Zhengrong (25 years ago, 18-Sep-01, to lugnet.robotics.rcx.legos, lugnet.robotics.rcx.java)

(...) The higher the power level the harder the stop. But the power level before stop() is not used, it always uses power level 7, and you can set it lower only afterwords. (I think that ought to change.) Jürgen (25 years ago, 9-Sep-01, to lugnet.robotics.rcx.java)

Hi there, I've just been playing around with a vehicle with a motor for each of the two main wheels. If I don't load the RCX with anything else than these two motors and set their respective speeds to 0 and 7, it drives in a nice circle with a small (...)

If you downloaded leJOS 1.0.2.RC6 you should download and install 1.0.2.RC8 instead as there is a bug in RC6 that causes the RCX to ignore sensors and buttons for several minutes. Apologies for the inconvenience - Paul Andrews. (25 years ago, 2-Sep-01, to lugnet.robotics.rcx.java)
