JD is a fully functional humanoid robot kit built with ez-bits. This humanoid design is fun and educational! JD boasts 16 degrees of freedom with metal gear heavy duty servo motors!

The camera in the head of this robot can be used for vision recognition (colour, motion, glyphs, QR codes, faces and more). There are 18 RGB LED's in the eyes of JD, which can be animated for unlimited expressions. The included EZ-Builder Software makes it easy to create customize movements and programs.


A humanoid that walks right away.

JD includes apps for walking, dancing, and even playing the piano! The EZ-Builder Software includes an amazing and easy-to-use animation GAIT feature called Auto Positioner. This allows you to create movement animations for your robot to walk, dance of give high fives! The animations can be triggered by other input controls, such as Speech Recognition, Vision Tracking, Joysticks, Wii Controllers, and more.


Interactive and Social

JD's eyes have 18 RGB LEDs (9 per eye), which can be configured to animate patterns with 1 million colour combinations. A robot wouldn't be a robot without a camera for vision recognition. So, a camera has been installed in the head which can track and learn colours, faces, motion, glyphs, and more.


Grippers provide interaction

The compact grippers are powered by strong metal geared servo motors, allowing your robot to interact with soft, light objects. We recommend coloured foam balls - the kind you at any value, hobby, or department store. They are perfect for your robot to grip and interact with.


Simply clip 'n' play

Customize your robot with ez-bits. All ez-robot revolution parts include ez-bit connections. Simply slide the tab into the slot to establish a secure bond. The parts may be seperated by sliding them apart.  Multiple ez-bits can be connected together to make arms, legs, or anything else you dream up!


Education in the classroom, and at home

In the classroom or at home, ezrobot Revolution has a big impact on education. Learn about robots, and have fun doing it! With hundreds of tutorials, no questions are left unanswered. Personalizing your ezrobot with new behaviours will teach students how robots walk, see, hear and interact with their surroundings to solve problems.
