THE electronic policeman in the movie Robocop is a crime fighter. In Hong Kong, there are two robot policemen who do not engage in catching thieves but are involved in public relations work. Both Robotcops were made in the United States. The first, known as Mr Ji Jing (Smart Policeman), is seven years old and started working for the Hong Kong police force in 1988. He tours schools and appears at police functions to promote the anti-crime message among children. Talking with his synthesised voice in Cantonese and English, Mr Ji Jing has been a big hit with children, who are not bothered by the fact that he is actually operated by a police officer in the vicinity through remote control. When Mr Ji Jing moves around, his head also moves. He can shake hands and has a variety of flashing lights, all of which make him look like a real robot. He has proved to be an excellent public relations officer for the force. He makes more than 20 visits to schools every month. However, after seven years of service, he needed a successor. His younger brother, Mr Ji Ling, arrived in Hong Kong last month. He has a strong build, and a height of 1.65 metres and weighs about 90 kilograms. Early this month, the Robotcop brothers made their first appearance at an unveiling ceremony at the Police Sports and Recreation Club in Mongkok. A new crime prevention bus was also shown to the public for the first time. The bus, which cost $1.5 million, is equipped with various kinds of display items concerning household, personal and vehicle security. Officiating at the ceremony, Tsang Yam-pui, the Police Director of Crime and Security, said the new exhibition bus would spread the anti-theft message around the territory.
