A final-year engineering student has designed an interactive toy car that listens to children’s spoken answers to simple maths questions. Her invention could one day help identify early learning challenges before they go unnoticed for too long!
Stellenbosch, South Africa (14 May 2026) – South African student Camryn Abrahamson, supervised by Professor Herman Kamper of Stellenbosch University, has built a unique toy car as part of her mechatronic engineering final-year project.
The car asks children basic numeracy questions, listens for their spoken response, and reacts to their answers accordingly!
In South Africa, many children fall behind in foundational maths without anyone realising it early enough, due to classes being too large and limited access to specialist assessments.
Camryn’s clever prototype aims to explore whether playful, affordable technology could support early screening in a more accessible way, without replacing teachers or formal evaluations.
As per the university, the system was designed to work with limited South African language and children’s speech data, yet still achieved promising results in both English and Afrikaans.
The final system achieved 79% accuracy on English child speech and nearly 77% on Afrikaans child speech, significantly outperforming existing tools that reached just 57% on English and 22% on Afrikaans.
The toy itself was 3D-printed and is powered by a small single-board computer, with a little screen acting as its face and headlights providing visual feedback to children.
For now, the toy car remains a research prototype, but it’s a compelling one, showing how thoughtful engineering designed with real educational needs in mind can open up new possibilities for the children who need support most!
“The result is a working prototype that demonstrates how speech technology might support early numeracy assessment in a more natural way for children. Future work could expand the vocabulary beyond single digits, improve the system’s handling of unexpected speech, and move more processing directly onto the toy itself. For now, the project stands as a strong example of engineering shaped by a real educational constraint and carried through into a working device.” writes Robert Kellerman of SU.
