    Screen-Free Coding & Sequencing (Ages 4–6)

    The WhalesBot U20 Pro introduces structured coding through an engaging, screen-free system. Students use physical coding cards alongside the interactive coding pen to create simple programs, encouraging logical thinking and step-by-step sequencing.

    This approach supports early computational thinking while remaining developmentally appropriate for younger learners.


    Controller, Coding Pen & Intelligent Modules

    The system includes a programmable controller with built-in motors, alongside a dedicated coding pen used to scan and execute coding cards. 

    Students can explore:

    • Forward and reverse movement
    • Turning and timed motion
    • Obstacle detection using the ultrasonic sensor
    • Light and sound feedback

    The intelligent motor and ultrasonic sensor introduce students to real robotics concepts such as sensing distance and reacting to environmental changes. 


    Technical Specifications

    • Controller battery: 1500mAh lithium battery
    • Coding pen battery: 430mAh lithium battery
    • Transmission: 2.4GHz wireless pairing
    • Effective usage distance: within 10 metres (open environment)
    • Operating temperature: 0°C–40°C

    This makes the U20 Pro particularly suitable for early primary STEM, coding rotations and structured robotics clubs.
