 | | How to read the touch sensors on the Scout in NQC?
|
|
All, I'm feeling pretty stupid right about now. I've read the NQC docs, looked in the newsgroups, books, etc, but I can't seem to figure out how to read the touch sensors on my Scout. I want to implement a bumper checking task but no matter how I (...) (23 years ago, 16-Dec-01, to lugnet.robotics.rcx.nqc, lugnet.robotics.scout)

Thank you for these posts! This idea of creating a table of arctangents is just what I need. I'll let everyone know how it works after I redesign the racer. (The prototype, designed for speed, experienced a significant mechanical shock when it (...) (23 years ago, 14-Dec-01, to lugnet.robotics.rcx.nqc)

Hi Richard, No, NQC does not implement any of the trig functions. However, you can do it yourself. The idea is to use a second order polynomial to approximate the sine function. You can get pretty good accuracy (within about 5%) if you break up the (...) (23 years ago, 12-Dec-01, to lugnet.robotics.rcx.nqc)

(...) Hi Rich, Have a look at (URL) where you can find various tips around trig-functions under the restriction of integer values. Claude (23 years ago, 13-Dec-01, to lugnet.robotics.rcx.nqc)

(...) Hi Rich, there are no trig functions, because there's no float. I had the same problem and was able to approximate these values. I created two tables with the necessary values. The first table includes the values of the tangens of a angle. (...) (23 years ago, 13-Dec-01, to lugnet.robotics.rcx.nqc)

Hi! I'm working on a project where a robot needs to travel a right triangle with unkown side lengths. Basically, the robot starts at a point in a room, travels perpendicularly toward a wall, turns 90 degrees left when it hits, and when it gets to (...)

Yesterday, I uploaded release 3.3.2.13 of BricxCC to my website: (URL) version fixes the access violation on calling the UpgradeRegistry method at startup (not all users encountered this problem). I am beginning to implement the "save desktop" (...) (23 years ago, 4-Dec-01, to lugnet.robotics.rcx.nqc)

(...) I'd be happy to leave the MDI world behind and switch to a tabbed page control for handling multiple files. But I would need to get a feel from the user community to see whether that would be a problem. There are some known problems with (...) (23 years ago, 2-Dec-01, to lugnet.robotics.rcx.nqc)

(...) I've discovered a really stupid bug in my code that was causing the access violations in version 3.3.2.12. This bug has been there since I introduced the registry upgrade feature (3.3.2.2) as far as I can determine. It has been fixed but I (...) (23 years ago, 2-Dec-01, to lugnet.robotics.rcx.nqc)
