Step 3 Discussion
First，ask students to think of what the other two laws for robots might be.
Three laws for robots：
1.A robot must not injure human beings or allow them to be injured.,
2.A robot must obey the orders given to it by human beings as long as human beings are not injured.,
3.A robot must protect its own existence as long as human beings are not injured；and as long as the robot
does not disobey human beings
Next，in groups，discuss Asimov's three laws for robots and exchange their opinions with each other.(Several
minutes later，ask some students to present their opinions to the rest of the class.)
A sample of opinions
Opinions_for_the_three_laws
Robots are tools for humanity.Without the three rules，they would become a danger to human beings.Without
the three rules，perhaps they will kill us.Robots，so far，are strong.Robots have fast computational brains，and they
might not have the capacity to understand things，but if they ever do，they'll likely be better than us at it.If we don't
put laws，or rules，or mechanisms in place to ensure that we don't create something that can destroy us，we'd be
running a careless risk of destroying ourselves by negligence or omission，wouldn't we?
Opinions_against_the_three_laws Without the three laws，robots would eventually become more intelligent and physically stronger than their
human creators.
Rather than guiding and adjusting the robot towards good，ethical behaviour，the Three Laws act as a barrier
to freedom，creating a free－will prison，an apt metaphor because，like the prisoner in jail，the robot is confined
to the behavioural steel and concrete walls of its mind.
To imagine what this would like，think back to your childhood.At some point，you wanted something like a
