Pixy2 can learn to detect objects that you teach it, just by pressing a button. Additionally, Pixy2 has algorithms that detect and track lines for use with line-following robots. The algorithms can detect intersections and “road signs” as well. The road signs can tell your robot what to do, such as turn left, turn right, slow down, etc. And Pixy2 does all of this at 60 frames-per-second.
