Inspire deep and joyful learning with the Hummingbird Duo Robotics Kit! The Hummingbird Robotics Kit is comprised of lights, sensors, and motors which allow students to build a robot out of any materials. The power of Hummingbird is in its flexibility - the same reusable kit can animate a poem, model the human arm, build an autonomous rover, or create a pinball machine.
