Today we downloaded some funky app and it controlled a little robot ball. The ball moved when you swiped on the screen. We made it knock pins down, we raced other robots from other people in the class. We made them play fight and more stuff. It was funny seeing how it moved. I also drove it into one of my teachers classes and just drove it around in there for a while. He was nice and seemed to like it too. Our ball was red and pink but others robots were red and white, red and blue, and other colors like red and yellow.
