Richard looks at DIY, including robot lawnmowers, the world's safest saw, an automatic wallpapering machine and the latest 3D printers capable of making plates and cutlery in minutes. Richard is not a fan of doing it yourself and believes that gadgets should be able to do all the work for you. So he tests the latest safety tools, building machinery and lawnmowers, all of which promise to take the strain and pain out of decorating your home. He also sets himself a challenge: to makeover a room in his house using robots and gadgets and without him having to lift a finger.
