    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 or 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 color combinations. A robot wouldn't be a robot without a camera for vision recognition. So, we installed our a camera in the head which can track and learn colors, objects, faces, motion, glyphs, and more.

    ezrobots are visual learners.

    The camera features advanced vision learning, detection and tracking abilities. Your ezrobot can interact with objects, colors, faces, motion, glyphs, and QR codes!

    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 colored foam balls – the kind you can find 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 ezrobot Revolution parts include ez-bit connections. Simply slide the tab into the slot to establish a secure bond. The parts may be separated 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.

    Children playing with robots at home, and at school.

    In the classroom or at home, ezrobot Revolution has a big impact on STEM education. Learn about robots, and have fun doing it! With hundreds of tutorials, no questions are left unanswered. Personalizing your ezrobot with new behaviors will teach students how robots walk, see, hear and interact with their surroundings to solve problems using a combination of science, technology, engineering and mathematics. Visit the EZ-Robot School!

    Live Streaming Video.

    Robot vision with streaming live video

    Give your robot or IoT project the gift of sight with live real-time streaming video. View the video on your mobile device or PC over the WiFi connection of the EZ-B.

    Streaming Audio - Music, voices or sound fx.

    Robot streaming audio of music, voices and sound fx

    Robots need a voice! The EZ-B has a built-in speaker to stream audio in real-time from the PC or Mobile Device. Play music, sound effects or even text-to-speech through your robot or IoT project.

    Software that's easy to use.

    Heavy duty digital servo motors.

    A close-up view of the heavy duty servo motors used in e z robots.

    Inside the HDD servo-motors are full metal gears and real ball bearings that lift 19 kg/cm! The metal gear and ball bearing internals will withstand a high load. These servos have enough strength to let your robots walk, move or lift. We engineered these servos to be tough from years of R&D, check out our demonstration video!
