Visitors look at a robot performance at Elexcon 2017 which kicked off at the Shenzhen Convention and Exhibition Center on Thursday. Four robots in red dresses, dubbed Murata Cheer Team, are the fourth edition since they made debut in Japan on Sept. 25, 2014. Each robot, which is 36 cm tall and weighs 1.5 kg, is equipped with three gyroscope sensors, which will detect the movement of its teammates. The three-day Elexcon has attracted high-tech companies showcasing their latest technologies at the fair.
