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)
