A Lego prosthetic arm for disabled children won the grand prize at the Netexplo forum for digital technology in Paris on Wednesday.
Carlos Torres, the designer of The IKO Creative Prosthetic System, made the prosthetic arm compatible with Lego parts and can have differents colours and shapes.
"Torres wanted to help children with malformed or injured arms feel less isolated by making their disability feel less of a burden or a stigma," the event organisers said.
"As well as technology, imagination can help children overcome a handicap."
Torres' design was the winner amongst a mobile phone app that can translate all 11 South Africa languages as well as a Japanese robot that is able to score high grades at school exams.
