[oopic] Re: Distance calculation problems

Why bother with caculations when a quick empirically-derived answer
will do? A pair of GP2D120s, angled 30 to 45 degrees left and right, to
tell you when something is too close - the digital trigger ones, not
the rangers. You can get a trigger range of 9 to 30 inches or so. Check
the Hobby Engineering website.
Part of robotics design lies in knowing (or guessing) when to go with a
workable compromise. Identify what is important and stay focused.
