25
How high would the running cost of automation in a nuclear power plant be?
The running cost might be lower because fewer people are needed, but maintenance could be expensive
26
How would safety be affected by automation in a nuclear power plant?
There would be a lower risk of human error, increasing safety, and people wouldn't need to work in dangerous places, increasing their safety
27
How would people's jobs be affected by automation in a nuclear power plant?
Some jobs would be replaced for the functions the system does, but new jobs would be made to maintain the system
28
How would precision and length of work be affected by automation in a nuclear power plant?
An automated system would measure and perform actions with more precision and monitor the power plant continuously, causing fewer errors
29
How high would the initial cost of automation in a greenhouse be?
The initial cost may be high for the installation and programming of the system
30
How high would the running cost of automation in a greenhouse be?
Despite the cost for electricity and maintenance, as the system is small the running cost may not be high
31
How would automation in a greenhouse affect safety?
Safety may not be relevant as a greenhouse is likely not a dangerous place
32
How would automation in a greenhouse affect people's jobs?
It might replace the jobs of people who monitored conditions, but this is unlikely to be a large number
33
How would automation in a greenhouse affect precision and length of work?
The system would be able to adapt as soon as there is a problem, and although precision isn't as important it would allow readings to be more accurate and let instant changes be made
34
What is a robot?
A mechanical device that performs an action, usually one a human would perform
35
What is robotics?
An area of computer science which covers the design, construction and operation of robots
