From: Ash Morgan Subject: Re: Triangulation Problem To: rusin@math.niu.edu (Dave Rusin) Date: Fri, 31 Mar 1995 12:06:07 -0800 (PST) Dave-- Thanks for all your help on the problem. I followed your construction and I think everything checks out how you typed it. The purpose for finding the coordinates is for my robotics research. A robot will be placed inside a triangle with IR beacons at each vertex. The robot will have a servo motor mounted on top and can sense when it's pointing at the IR beacons. From this we can measure the inside angles which you called a and b. From that information I need to calculate the coordinates of the robot so I can use that information in mapping and navigation. When I had first attempted the problem I came very close to your solution. I knew that the angles should uniquely determine your place in the triangle, so I decided to hold one angle constant and see what path it would trace. However, I thought the path was more parabolic than circular and the form I had the equation in which described the curve was not recognizable as a circle. Anyway, thanks again for your help. | | | | Ash \ / `.__.'
