This was just a freelance job ( no royalties, dangit) but it was a fun project earlier last year. I love getting paid to build robots! They pretty much kept my original design (tricycle front wheel drive & steering) and all my features (pen changer turret, line following, color sensing, edge detection). And now that the company Educational Insights has announced it, I can share some of my early prototype tests. I hope they can execute in production!
