A Taser factory in Arizona is the epicenter of the robot revolution, and its success is foreshadowing the rise of a $370 billion industry

• Axon started using robots to assemble cartridges for its flagship product, the Taser, 10 years ago.
• Automation helped the Arizona-based giant bring production back into the US and boosted its output by four times.
• This is one example of why factory automation is expected to be a $370 billion industry by 2025.

Ten years ago, Axon started using robots to assemble cartridges for its flagship product, the Taser. Automation helped the Arizona-based giant bring production back into the US and boosted its output by four times.

The big picture: This is why factory automation is predicted to be worth nearly $370 billion worldwide by 2025, up from $191 billion in 2017. Robots build quickly and cheaply, and they don't make mistakes or get tired.

Since Axon began automating manufacturing in 2009, it has bought $18 million worth of automated equipment, the company tells Axios.

• But as its output has grown, its workforce has, too - from 120 to 420 manufacturing personnel.
• An Axon spokesperson tells Axios that automation is "not about replacing jobs - it's about using automation to free up our workforce to do different jobs." This is a common refrain among companies that don't want to be seen as unfeelingly replacing humans with robots.

Reality check: They can't replace people yet, even if they wanted to.

• As we reported this week, robots aren't yet dextrous enough to handle delicate assembly, or flexible enough to deal with any uncertainty in the production line.
• When robots are cheaper and more capable, you can bet that companies will start cutting staff.
