Thanks to our visiting robots, one of the students was inspired to bring his Hexbug Nano as well. If you’ve never encountered one of these little things, you’re in for a jittery surprise. They move around via vibration and are great for following paths and mazes set out by our wee inventors.
Our pile of recycled items, collected for robot designs, took on new life as tracks for robot motion. Three long cardboard tubes were nested together with varying success. Two of the tubes were narrow, the size of a paper towel tube, while one was noticeably greater in girth. The first attempts placed the smaller tubes on either end of the larger. This led to the Nano getting stuck at the entrance of the third tube where it was slightly higher. After much adjusting, some squishing, and some good old-fashioned teamwork, the children discovered a way to make the tube sizes more even. They simply unraveled the end of one of the smaller tubes, creating a larger opening that could still slide into the wider tube.
