James's mum is a real computer whizz. She designs computers that can launch space missions.
But she's not quite so good at ordinary, boring mum stuff!
James is forever turning up at school without his dinner money or permission forms for outings.
Then his mum has an idea - she'll make him a mother-robot.
The Robomum is certainly a brilliant machine. She shops, washes and cooks - and quickly learns all James's favourite recipes. She tests him on his spelling, helps with his maths and makes sure he never forgets his swimming kit. But when James gets ill, he soon realizes that a computer could never replace his mum when he really needs her.
