(...) I haven't seen this but I imagine that it is similar to the Control Lab version, only taking advantage of the multi-processing capability of the RCX. At least that was my $0.02 during the brainstorming session for this packet. :) (...) If this (...)

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)

I've posted a new version of Robot Controller ---the ideal companion to NQC for Mac OS X users--- with improved error handling. Also a better web page explaining how to use it. Download from: (URL) the way, has anyone tried it? It would be nice to (...) (23 years ago, 13-Dec-01, to lugnet.robotics.rcx)

(...) 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 (...)

(...) If I understand you correctly, you wish to use the IR port built into your laptop instead of the IR tower. To the best of my knowledge this is not possible. John Hansen (23 years ago, 12-Dec-01, to lugnet.robotics.rcx)
