Predictions of many robots in industry have yet come true. For ten years or more, manufacturers of big robots have explained how their machines can make industry mom competitive and productive. The maker for 【21】______ robots is oversupplied now, and the driving force of the robotics(机器人学) revolution is 【22】______ to be with makers of machines that handle a few kilos at most. 'Heavy-robot manufacturers are in some difficulty 【23】______ finding ustomer. They are offering big 【24】______ just to get in the door. There has been a 【25】______ growth everywhere in the numbers of robots, so we admit we are either deceiving 【26】______ or that the market is slowly growing. 'said John Reekie, chairman of Colen botics. 'The following things must happen 【27】______ the robotics revolution to occur. We must achieve widespread robot literacy(文化), 【28】______ there has been a computer 【29】______ program, there must be a robot prices. 【30】______ , some kind of artificial intelligence needs to be 【31】______ . Colen makes educational robots and machine tools. It is small 【32】______ with companies like ASEA or Fujitsu Fanuc. But Colen with others and departments in universities such as Surrey, Manchester, and Durham possess an advantage 【33】______ the giants. The big companies sell very expensive 【34】______ to businesses with expert knowledge in automation. The 【35】______ companies make robots for teaching people, and now they have realized that there is a need for small, 【36】______ robots that they can meet. The little companies either bring their educational machines 【37】______ an industrial standard or design from the start. One technique that they all adopt is to choose 【38】______ components where possible. The major cost of making 【39】______ their models is the electronics, which will fall in price. There is 【40】______ scope for reductions in mechanical costs. The sue of standard parts, which are easily replaced, should give these robots a mechanical life of something in the order of five years. 【21】
