8 robots that have already entered the workforce in a big way

There's been a lot of discussion as to whether robots will one day take our jobs, but the reality is robots have already entered the workforce in a big way. 

In 2014, there were an estimated 1.5 million industrial robots in use and that number is expected to shoot up to 1.9 million by 2017, according the International Federation of Robotics. 

Currently, robots are most prevalent in the manufacturing industry. However, as bots become more capable and cheaper for employers to adopt, they'll increasingly begin to move out of factories and into new settings. 

In fact, some bots have already started popping up in restaurants, hospitals, and even on movie sets. 

Here's a look at eight robots currently working with people everyday.
