The tentative agreement between the Metropolitan Transportation Authority and the union representing its workers has thrown the spotlight back on the ongoing contract negotiations between the city and its civil servants.

The dispute has stretched on for years as the 152 unions, which represent approximately 300,000 workers, demand billions of dollars in retroactive raises.

But part of the workforce at some of these agencies have not been part of the negotiations. That’s because they don’t get paid. And they don’t talk. They are robots.

Let’s take a look at some integral members of city government who are not usually in the public eye.

The FDNY asked SuperDroid Robots to make the department a custom robot after extensive testing starting in 2011, including a four-day trial at the Disaster City simulation training center in Texas. The city paid $99,790 for the robot, which was delivered on June 30, 2013.

Andros HD-1

The NYPD is upgrading two of its Andros HD-1 robots, which are the same robots shown in the first few minutes of The Hurt Locker. They will be getting new radios and new arms “that are more dexterous and capable of lifting more weight,” according to Matthew McQueen, a spokesman from Northrop Grumman. “With these upgrades, we’re giving the NYPD’s HD-1 robots HD-2 capabilities.”
