Robotic shopping trolley becomes a reality after 13-year-old boy drew one to help his grandmother

Engineers have developed a robotic shopping trolley for elderly customers based on a drawing by a boy who simply wanted to help his grandmother. Aidan McCann, 13, dreamed up a push cart with height adjustment features to help his grandmother Lydia who'isn't very strong'. He witnessed how the 4ft 11in 76-year-old finds it difficult to carry groceries from the shops and perform other physically demanding tasks due to her height. Bosses at engineering giant Doosan Babcock were so impressed with Aidan's design they selected it as their overall winner at the Scottish Engineering Special Leaders Award 2015 Users can make the trolley go up and down by the flick of a switch. The idea is to lift bags of shopping towards the users so that they don't have to bend down and lift it up themselves.
