A Line-following Robot in Scratch


   I recently received a comment in my Scratch Messages box from VauHaEs, a Scratcher in Germany. He liked and complimented one of my shared projects (online at the Scratch web site) so I clicked on his name to view his profile. There, I was able to view all of the projects he had uploaded to the Scratch web site and I was immediately intrigued by his line-robot project
   Below is a screenshot of line_robot in action. When the green flag is clicked, an animated robot with two long, stiff arms tracks along the yellow line.
   In line­_robot, both the robot and its control are implemented in software, and the software is FREE!  I think this might be important to those that would like to ‘get into robots’ but can’t afford the $200+ cost of a Lego Mindstorms® kit.
   I've written a short description of the code VauHaEs wrote for this project. I remixed his project to simply the coding.
  You can view and download my remix at this link.
