Please note that this Hummingbird Bit model uses micro:bit as its processor; you must have micro:bits in order to operate the kits. 

Inspire deep and joyful learning with the micro:bit-powered Hummingbird Bit 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. Hummingbird epitomizes a low-floor, high-ceiling approach: absolute beginners can build & program a robot in minutes, but continue learning advanced engineering & programming for years.
