"Heavy-robot manufacturers are in some difficulty【3】finding customers. They are offering big【4】just to get in the door. There has been a【5】growth everywhere in the numbers of robots, so we have to admit we are either deceiving【6】or that the market is slowly growing," said John Reekie, Chairman of Colne Robotics. "The following things must happen【7】the robotics revolution to occur. We must achieve widespread robot literacy (文化),【8】there has been a computer literacy program, there must be a robot literacy campaign. We must also【9】not just a cut in, but a collapse of robot prices.

Colne makes educational rol)Ots and machine tools. It is small【12】with companies like ASEA or Fujitsu Fanuc. But Colne with others and departments in universities such as Surrey, Manchester, and Durham possess an advantage【13】the giants. The big companies sell very expensive【14】to businesses with expert knowledge in automation. The【15】companies make robots for teaching people, and now they have realized there is a need for small,【16】robots that they can meet.
The little companies either bring their educational machines【17】an industrial standard or design from scratch (从头做起). One technique thai they all adopt is to choose【18】components where possible. The major cost of making【19】their models is the electronics, which will fall in price. There is【20】scope for reductions in mechanical costs. The use of standard parts, which are easily replaced, should give these robots a mechanical life of something in the order of five years.
