| | | 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 (...)

| | | | | 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, 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)

| | | | | | 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)
