Supermarket thefts could be a thing of the past thanks to an'ominous' security robot that looks straight out of Doctor Who. Tesco has confirmed it is using the Dalek-like machines, which detect the presence of thieves thanks to 360-degree cameras. Placed near the entrance of Tesco stores in the small hours, the bot shouts at any intruders in an'angry Northern Irish accent' and sends alerts the authorities. It's hoped the robot does a better job than human watchmen because it can't fall asleep on the job, as long as it's been sufficiently charged. However, at 100,000 per month to hire, the robot doesn't come cheap.

Richtech Robotics spokesman Timothy Tanksley and Richtech Robotics COO Phil Zheng joined'Fox & Friends Weekend' to show how his company's robot barista can serve coffee on FOX Square. A shopping mall in Ohio is integrating cutting-edge AI technology into its safety team in the form of a 400-pound robot security guard. "He's our secret agent man," Stacie Schmidt, vice president of marketing at Crocker Park told local media of the new security robot. Crocker Park is an open-air shopping mall located in Westlake - a suburban town located about 15 miles outside of Cleveland - which sees nearly 10 million visitors a year and is home to 1,000 residents in luxury apartments. This month, leaders of Crocker Park introduced SAM, a 420-pound, 5'1" autonomous robot that will patrol sidewalks and act as a "watchdog," according to a press release provided to Fox News Digital. "Our priority has always been to provide a safe and secure environment for everyone who visits our center, and the Knightscope robot will play a crucial role in enhancing our existing security measures," Sean Flanigan, vice president of security at Stark Enterprises, which owns Crocker Park. SAM, which was built by California-based robotics company Knightscope, uses 360-degree video streaming and recording video capabilities to monitor areas and alert authorities to any potential issues. The robot can work 24 hours a day, rain or shine. "[SAM's] AI algorithms enable it to detect anomalies and issue alerts to the on-site security team in real-time.

A team of three autonomous patrol robots are now providing security at the Tokyo metropolitan government building. The robots are SQ-2 models produced by Seqsense in Tokyo and they're equipped with multiple cameras that can broadcast video directly to human security personnel at a central location. These robots look decidedly more R2-D2 than Robocop with spinning cameras on their heads that constantly whirl around and can make 3-D maps of their surroundings. The robots are SQ-2 models (seen above) produced by Seqsense in Tokyo and they're equipped with cameras that can broadcast video directly to human security personnel They do still have artificial intelligence capabilities that can detect people and other obstacles to avoid any collisions on the predetermined patrol routes. They even have hand sensors so that people in the space can request help from human guards, but they are not meant to fulfill all the duties of a regular human security guard.

We are surrounded by surveillance cameras that record us at every turn. But for the most part, while those cameras are watching us, no one is watching what those cameras observe or record because no one will pay for the armies of security guards that would be required for such a time-consuming and monotonous task. But imagine that all that video were being watched -- that millions of security guards were monitoring them all 24/7. Imagine this army is made up of guards who don't need to be paid, who never get bored, who never sleep, who never miss a detail, and who have total recall for everything they've seen. Such an army of watchers could scrutinize every person they see for signs of "suspicious" behavior.

A shopping centre in Los Angeles has introduced its first robot security guard to patrol the mall to help identify potential shop lifters. The robocop-style guard is capable of picking up video footage and sending information back to security headquarters, so they can respond quickly. It is equipped with a 360-degree camera, WiFi, sensing units and can stream live video, read license plates and detect people. The bot operates autonomously and looks like a cross between a dalek from Doctor Who and the main character in Wall-E. The objective of the machine is to differentiate between a harmless passerby and a possible criminal.

A robot developed to serve as a security guard at train stations was shown to the press Thursday amid a growing need to boost safety in the run-up to the 2020 Tokyo Olympics and Paralympics. Equipped with a security camera powered by artificial intelligence, the robot can detect and report suspicious persons or objects at stations and is expected to help lower burdens on staff. It is named "Perseusbot" after Greek mythological hero Perseus and is 167.5 centimeters tall, 61 cm wide and 90.5 cm long. The robot will be tested at Seibu Shinjuku Station in Tokyo between Nov. 26 and 30. The robot can avoid obstacles and travel over uneven pavement during patrols. It can send alerts to the smartphones of security staff if it discovers objects left unattended for a long time or if it captures aggressive movements by individuals that could lead to conflict.

A start-up called Cobalt Robotics is making roving security robots for use in commercial buildings -- whether that's an office, data center or a hospital. The robot could help companies save money on human security guards: businesses spent almost $68 billion on physical security in 2016, according to industry research by Stratistics MRC. That number is expected to surpass $125 billion by 2022, with a hefty chunk of spending going to human security guards indoors. CNBC caught up with Cobalt Robotics CEO and co-founder Travis Deyle to see the machines in action at Fuseproject, the design studio of Yves Behar. Fuseproject helped create the look and feel of the Cobalt, which is more like consumer hardware than a piece of office equipment. Deyle founded Cobalt in 2016 after a stint working on a smart contact lens project for Google X, the search giant's experimental research lab.

The newest member of Yelp's security team awakes just after 8 pm, ready to begin its rounds. It traverses the lobby, gliding over polished concrete toward a small recess in the corner, where it inspects the emergency exit tucked inside. Last year, burglars tried to breach the office by rending the door from the building, frame and all. The low-resolution camera mounted in the lobby saw nothing. "We couldn't see what was going on inside the alcove," says Rick Lee, Yelp's head of security, who joined me on my late-night visit to one of the company's San Francisco offices.
