Robotics companies promise that video-camera-toting security robots can deter and detect crime. But many companies are rethinking the approach after a trail of canceled contracts and questions about whether the artificial intelligence-powered bots are meeting the needs of businesses and local governments.

Proof News found evidence of at least 21 security robot deployments since 2015. We contacted contract holders and combed news articles and determined that at least 13 of those programs have ended. Silicon Valley-based Knightscope secured the most security robot contracts, according to Proof’s analysis, and also suffered the bulk of cancellations.

For example, New York City’s then-Mayor Eric Adams installed a Knightscope robot on the overnight shift at the Times Square subway station, but the program was scrapped when the pilot expired in 2024. City leaders did not respond to Proof News’ questions about why the robot wasn’t renewed. By the end of its assignment, it was reportedly gathering dust in an empty storefront.

Outside Columbus, Ohio, the city of Dublin pulled the plug on a Knightscope robot in May, ending its two-year pilot program after less than 10 months. The city enlisted the robot, dubbed DubBot, to patrol a downtown park, but city spokeswoman Robyn Gray said it “did not fully meet our operational needs,” and failed to identify any criminal incidents or lead to any tickets or arrests.

Sheila Sparks isn’t surprised. Her family has operated Sparks Protection Services near Columbus for more than a decade and said a human touch is essential to de-escalating sticky situations.

“A robot can’t do that,” Sparks said.

Seeking a new path forward in the security industry, Knightscope CEO William Santana Li said the company is forging a new model, combining its robots and AI-powered software with another key ingredient: human security guards. Knightscope announced it purchased Event Risk LLC, a national security guard firm, earlier this year.

Knightscope has incurred net losses since inception in 2013, according to its most recent quarterly filing with the U.S. Securities and Exchange Commission, and is $273 million in debt. Knightscope hopes its pivot to incorporate people will give it a greater share of the physical security market — which the company believes is worth an estimated $230 billion annually.

Li declined to answer questions about the disbanded programs, but said in an email, “Technology cannot do everything — and neither can people — but the combination can be very powerful.”

ROBOTS VS WORLD

Knightscope and other American made robotics companies could get a boost from the recent U.S. Federal Communications Commission ban on foreign-made mobile robot imports. Officials cast the move as a national security imperative given the machines’ surveillance capabilities.

But American roboticists are facing more than foreign competition. Robots have long struggled to navigate environments constantly in flux. AI can’t handle the ambiguous situations that security guards and police face daily, said Missy Cummings, a robotics professor at George Mason University. While AI decision systems perform well in narrow circumstances, she said, they can perform “miserably” as soon as algorithms are outside their training dataset.

“AI and robots for security have had a long problematic history,” Cummings said in an email, speaking generally. “I do not see this changing anytime soon.”

In 2016, a Knightscope robot deployed at a shopping center in Silicon Valley rolled over a 16-month-old boy's foot. The company apologized for the “freakish accident” at the time, saying in a statement that the robot veered to avoid the child, who ran backwards and directly into the machine. The next year, one flopped into a Washington, D.C. fountain. The company responded with humor, tweeting: “BREAKING NEWS: “I heard humans can take a dip in the water in this heat, but robots cannot. I am sorry.” Li, meanwhile, told the New York Times that the incident was under investigation and a new robot would be delivered free.

When asked about whether contracts remained active, representatives from neither property  responded.

Then there was a trial at the San Antonio International Airport in 2024. Spokesperson Ana Flores said its Knightscope robot struggled with badge scanning, communication, and finding its way around. A door alarm would sound, she said, but the robot wouldn’t respond efficiently. Airport leadership opted to not move forward with a one-year, $21,000 Knightscope lease following a one-month test.

Meanwhile, private security is booming. Security officers have proliferated in recent years as cities embrace private guards, who earn an average of about $40,000 a year, according to the U.S. Bureau of Labor Statistics, about half that of police officers.

Robotics companies pitch their autonomous robots — some of which can be equipped with cameras, facial recognition capabilities, and license-plate readers — as another set of eyes. They have no family to go home to and are happy to work nights and weekends.

Security robots promise “an alluring form of surveillance as a service,” Andrew Ferguson, a law professor at George Washington University, said in an email to Proof. In some cases their visible video cameras can “deter crime without having to pay a human being a salary,” he said, but it’s not clear that robots prevent or solve crimes better than people.

“They exist as a physical manifestation — a symbol, if you will — that someone is doing something to address potential crime,” Ferguson said. “Robots are a form of security theater, more optics than results.”

CRUMPLED CONTRACTS

Knightscope isn’t the only one seeing interest fizzle.

Officials in Salem, Oregon, powered off their Daxbots after a three-month pilot with the Oregon-based robotics company earlier this year. They had deployed three Daxbot robots to deter trespassing in a downtown parking garage. The robots recorded license plate numbers, captured photos of vehicles violating parking lot rules, and shared data with police.

Complaints about the parkade are “drastically down” since the pilot ended, according to Salem Police Sgt. Trevor Morrison, but it’s unclear if that’s due to traffic-calming devices or “residual results from the Daxbot patrols.” The pilot ended in April, with city spokesperson Nicole Miller citing no additional funding for robot security.

Daxbots have also disappeared in Tempe, Arizona. A viral video of one blue-eyed bot being outwitted by an onlooker who it demanded “leave the premises” made its way to “America’s Funniest Home Videos.” When asked about the contract, the mixed-use campus, IDEA Tempe, did not respond. Daxbot didn’t respond to Proof’s questions about why the Salem and Tempe contracts ended.

Adam Pioth, who posted the video, told Proof that he visited the robots frequently. A few months ago, he noticed the robots no longer shouted he was trespassing. Instead, he said, they would, “stop, look at me, and then just keep going really slow.” And then, he said, they were gone.

“Goodbye my friend,” Pioth wrote on Instagram in March, “and thanks for all the fond memories.”

Daxbot is recalibrating its business, rolling into another industry: automated sidewalk assessments. Proof identified at least nine cities nationwide that have contracted with the company since last September to send robots cruising sidewalks to check for compliance with the Americans with Disabilities Act.

Boston Dynamics is best known for its robotic patrol dogs, which were recently deployed to two World Cup stadiums. After Hyundai bought the controlling stake in the robotics company in 2021, it began pushing to develop mass-produced humanoid robots to work in automotive manufacturing.

Atlas, its humanoid robot, delivered the match ball to the referee during a game in July. But the strategy has also spurred rolling strikes at Hyundai Motor’s Korean assembly plants.

Critics claim police and security robots aren’t proven crime fighters, but are effective at one thing: surveillance.

In 2021, the New York Police Department ended its lease for a Boston Dynamics robotic dog and returned it, The New York Times reported, following public outcry. U.S. Representative Alexandria Ocasio-Cortez called the tool — which could climb stairs and was equipped with cameras, lights, and a two-way communication system — “surveillance ground drones” being “deployed for testing on low-income communities of color.”

Boston Dynamics did not respond to requests for comment.

“What it’s really doing is building a mass surveillance system that is impossible to hide from,” said Brian Hofer, executive director of the privacy-advocacy nonprofit Secure Justice. “It is not a society I want to live in.”

Steve Rosta, retired highway patrol officer and co-owner of Direct Approach Security Services in Ohio, said robots’ cameras may act as a deterrent, and even catch videos of crimes, but he can’t see a future where the machines are more reliable than a human guard.

“I’m old school,” Rosta said. “Boots on the ground is always better.”
