A new security robot has a drone that it can send after intruders and get an aerial view of the situation. The 176-pound golf-cart-sized automated vehicle has 3D LIDAR sensors and GPS, along with other instruments that it uses to spot unattended bags and to differentiate between employees and intruders. If it spots a bag that remains unattended for five minutes, for instance, it raises an alarm and marks it for further investigation in case it’s something dangerous.

According to, the O-R3 robot created by the Singaporean startup Otsaw Digital can differentiate the people security personnel mark as employees from unknown individuals.

When the robot determines that a person is an intruder, it will send a drone after him up to around 328 feet away. The drone can be especially useful if there are obstacles blocking the vehicle’s way, since it can provide an aerial view of the area to expose potential hiding places.

Singapore expects robots to play a big role in its bid to become the world’s first smart city, and it sounds like Otsaw’s O-R3 fits its government’s vision perfectly. Clients will be able to rent one for $10,000 a month, which is slightly less than what establishments in the country are paying four security guards.

While the system can take over the low-level tasks, such as patrolling areas, from humans, though, Ling believes it can’t completely replace flesh-and-blood workers. O-R3, he says, can complement human security personnel hired for jobs that require a higher level of skills.

The company is also working on a smaller indoor version with no lasers and drones.
