WhalesBot U20 Pro Robot Kit (Ages 4–6) | Early Coding STEM

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.

A standard delivery charge of €6.95 will be applied to the majority of orders under €150. We usually don't charge delivery for orders over €150. Other charges may apply if heavier products (clay, plaster, reams of paper etc) or large equipment (desks, cabinets etc) are ordered, but we will notify you before the invoice is issued and goods are dispatched.
