It's been confirmed for the last 3 years or so that blow-up dolls have been radically updated. From a bag of air to a real-life robot with human features and moving parts- the blow-up doll 2.0 is none other than the "sexbot", and they are here to stay. Realistic sexbots are part of a growing $3 billion industry – aiming to create dolls that look and operate like real women. But now, they have gone past sex- now the robots can cook and clean.The new wave of sexbots aim to be more realistic and are made to create a more intimate relationship between the robot and human. The race to create the first fully robotic sex doll is on – and Matt McMullen is at the forefront. So who is this mad genius?
