Fresh from launching trials of automatic tills, Tesco has gone one step further by piloting a yoghurt-serving robot in its Covent Garden store. The Robofusion Yoomoo serves up various flavours of the frozen yoghurt brand, at £3.50 a pop. Store manager Martyn Pett said it “adds a lot of theatre” to his store, which has a high proportion of tourist customers. “It helps bring the digital world to Tesco customers in a unique and exciting way,” Tesco added.
