A MATLAB Program that uses a webcam to watch three different robots. It gets their positions online so it is possible to draw their paths and their inter-agent distances.
The robots have three different color labels. This program uses the RGB properties to detect the labels to find them. I used the code: Color Threshold written by Mr. Aaron to find the RGB properties of the labels offline. Drawings are done offline.
NOTE: the program works under MATLAB 7.6.0(2008.a) and NOT GUARANTEED to work under other versions without some changes.
