Today everyone chose electives. There were four to choose from, including robotics, 3d printing, micro worlds and my group Lego Digital Designer. The program that our group uses is the same as the program that the people at  Lego use to make new products. Instead of using LDD we got to use actual Lego, I built a tractor and tried to make steering that worked but it was too hard. I think our group is the best.
