World Plotter

This robot draws nearly the entire world on a blank white ball. For this robot the coordinates of the continents were prepared as a zigzag line, drawn with a green felt tip pen. After the continents are drawn the robot switches colors from green to black. With this pen the continents are labeled, AS for Asia, AF for Africa, NA for North America, SA for South America and EU for the European Union. After switching to the blue pen the oceans are labeled, PAC for the Pacific, ATL for the Atlantic, IND for the Indian Ocean.








This is a really cool post on the Lego Mindstorms webpage about a robot that draws out the continents and labels them. Go to the link to see more info!
Also Mike (the person that made the robot) has made many, many other plotters. They are all cool in their own way.
