Tired of waiting to welcome our new Robot Overlords? Help your children start the revolution with this accessible, creative robotics kit. The Twin Science Discovery Set uses easily combined electronic blocks to simplify and explain how complicated-looking technological devices work. Every module has braille on the back to help identify each component needed to build the circuits.


The Twin Science Discovery Set brings science experiments to life and teaches children robotics in an enjoyable and instructive way. It uses easily combined electronic blocks to simplify and explain how complicated-looking technological devices work. 

Combine different components and sensors to make self-propelled cars, robots, torches and simple circuits.

Each block is clearly labelled in braille, enabling mini-engineers to explore science through touch. The set contains 25 magnetically connected modules and 25 sample experiments which support innovation-focused thinking. Once they’ve mastered these, children can combine modules in hundreds of new ways and can create their own projects. (Hopefully none of them will ask you for “your clothes, your boots and your motorcycle…”)

The Discovery Set is an advanced kit recommended for children who are already interested in robotics.
