detect the presence of dangerous gases.Incredibly，the robot has a real sense of logic. If it comes across an obstacle it gets momentarily confused.It has to think about what to do and where to go next.Sometimes it throws a fit just like a real person.

　　The greatest problem，though，is cost.The money of the earliest research project was provided by the government，but that money had dried up，and it's not clear where future money will come from. Partly for that reason，and partly because of advances in safety，mining is not nearly as dangerous as it was in the past.Since 1990, fatalities(致命性) have declined by 67% and injuries by 51%，according to the National Mining Association.

　　Some experts predict that robots in mines will serve much of the same function that they do in the automotive industry. The robots do the most boring and dangerous jobs，but won't get rid of the need for human workers.
