Meet Edison - Radioactive Waste Locator Design Challenge

This video is copyrighted by Phil Grigonis. For this design challenge, Edison will help us locate some radioactive waste at a contaminated site. There are four drums of contaminated waste at the site, but we don't know where they are. Edison will bounce around looking for the drums, and every time he finds one, he will throw his lights on and play a song. Once he has found all four drums, the program should end.
