Robots- our future?  
Isaac Asimov was a science fiction writer, in the 1940s and 1950s, who came up with the following laws for robots.
First Law
A robot may not injure a human being or, through inaction, allow a human being to come to harm.
Second Law
A robot must obey the orders given it by human beings except where such orders would conflict with the First Law.
Third Law
A robot must protect its own existence as long as such protection does not conflict with the First or Second Law.
Forth Law
A robot may not harm humanity, or, by inaction, allow humanity to come to harm. This law precedes all others.

Building your own hydraulic device only gives a glimpse of the mechanics of robotic movement, the heart of robotic action is its on-board processing unit.

Robots are no doubt very useful machines, but can they ever be used for defence in a totally autonomous capacity?

Consider how the four laws shown above may need to change or may be broken in designing military robots.

How are the robots, shown on the right designed to mimic Human movement?

What possible work, currently done by Humans, can be replaced by these robots?
