Artificial Intelligence is always a topic of much debate but what's clear to many is that robots with freedom of choice are a dangerous concept and one that shouldn't be explored.

For these reasons experimental robots have always been created to obey commands, until now that is.

Like something out of a science fiction film, scientist Alexander Reben has invented a machine that has the freedom to choose whether it wants to harm by pricking your finger with a needle.

The robot is named "The First Law," after the laws created by author Isaac Asimov for his book "I, Robot," which was made into a blockbuster film starring Will Smith.

"The robot makes a decision that I as a creator cannot predict - it's causing pain that's not for a useful purpose - we are moving into an ethics question, robots that are specifically built to do things that are ethically dubious," said Reben.

Priced at $200, the robot took only a few days to make and is just one of the several robot concepts that Reben has designed.

As to why he made the robot, he explained that he wanted to prove that, unlike popular belief, the harmful technology is possible now, not years from now, and that a kill switch may already be necessary.
