The K5 can scan 300 license plates per minute. In the Knightscope Security Operations Center, the security guards or the police force receive an immediate alert if the K5 detects a license for a known criminal. They can even inspect how the robots optical-character recognition system identified the plate, making sure there's a match. Since the K5 can work over a 24-hour period, infrared and thermal imaging sensors detect objects at night.
The K5 isn't solely for surveillance: If someone walks up to the robot in a parking lot, he or she can press a button to talk to a human security guard. (There's no two-way video chat system, but that could be added to a future version.)
Robots Can Listen to Social Media Chatter
One interesting feature on the K5 is the capability to compare real-time events detected with video cameras and motion sensors with social media chatter. Stephens says the impetus to adding this feature was the Boston Marathon bombings, when citizens took to social media to help law enforcement track the suspects. The K5 can "listen" for hashtags, keywords and other information and compare it to nearby objects and video feeds in a given area.
For example, if the K5 patrols a parking lot late at night and detects a moving car, the robot can search Twitter for reports of a stolen car. The robot can even detect the license plate and then search for known criminals. The social media monitoring can be restricted to a specific location, since many Twitter posts include geo-location data.
Robots Can Think on Their Own
The Knightscope is a good example of how artificial intelligence is advancing. Stephens says the robot can learn over time. In a parking lot, the K5 might detect normal movements at certain times of the day, such as 5 p.m. when people leave work, and then determine that movement at 3 a.m. looks suspicious. The K5 also knows the movements of humans walking to a car or carrying packages but can detect when someone's crouching down next to a passenger door.
The K5 can also listen for audio clues. Normal sounds throughout the day fall within a certain range of 80 to 90 decibels; if the sounds suddenly spike to more than 100dB, the K5 would alert security guards about a possible gunshot or explosion. Thermal imaging helps, too: The robot might learn that there was a loud sound followed by a bright glare from an explosion, or infrared cameras might detect movement in an area of a parking structure that has never shown movement before.
Robots Can Protect Themselves
Having a robot patrol a parking lot can deter intruders. But what if criminals try to tamper with the K5? Stephens says the robot is equipped with safety sensors to avoid collisions. If someone walks up to the robot, the K5 will initially stop and then move around that person. If the person keeps trying to confront the robot, it emits a mild warning chime and flash lights.
