In today's security-conscious world, surveillance robots are becoming increasingly popular for both indoor and outdoor use. These robots typically come equipped with a mobile platform suitable for outdoor use and a range of sensors, including microphones, radar, teleoperated pan-tilt cameras, and motion detectors. They are also capable of automatically recharging themselves, allowing them to extend their missions and cover large areas.
To ensure comprehensive coverage of large areas, several robots can be coordinated or one robot can strategically place active sensor probes on the ground to transmit information to the parent robot and form a sensor network. These probes are lost when their energy is used up or are collected by the robot at the end of the mission to be re-used.
The core security applications of these robots include access control, anomaly detection, and alarming, and detection and inspection of objects. They are ideal for environments where surveillance by personnel is tedious, costly, or hazardous, including military bases, government units, factories, museums, corporate headquarters, chemical plants, nuclear power stations, and more. These systems are available at a cost ranging from USD 25,000 to about USD 150,000, depending on the machine's performance and sensor equipment.
In industrial settings, several security robots are available for use. SMP Robotics has developed a security robot of its S5.2 series for autonomous patrolling in protected areas. It is designed for intelligent video surveillance and offers 360-degree panoramic video surveillance, including human and face detection and audible warnings. Knightscope K5, on the other hand, is a 1.5m tall mobile robot that utilizes predictive analytics and collaborative social engagements to predict and prevent crime. Operation areas include schools, hotels, auto dealerships, stadiums, casinos, law enforcement agencies, seaports, and airports.
Similarly, EOS Innovation’s e-vigilante is a security robot that moves at speeds between 5 and 10 km/h, follows pre-programmed rounds, and identifies anomalies, break-ins, and movements. The robot notifies the security service operator located outside the facility, transmitting in real-time video materials and information that are displayed on the map of the facility. The security operator can then take control of the robot remotely to assess the situation, categorize the alert level, and take any necessary measures while staying out of physical danger.
Finally, unmanned ground vehicles (UGV) are also available for surveillance and disaster relief. These platforms are propelled by tracks and run-on batteries, and most have manipulators for handling explosive devices. They are usually not very fast, and their stair-climbing capabilities require a skilled (tele-)operator. Some popular UGV models include Packbot by Flir, Cutlass or Wheelbarrow, TeleMax, Teodor, the Talon, and the Defender.
Overall, security robots offer an effective and reliable solution for surveillance and disaster relief in a wide range of environments, and their use is only expected to grow in the coming years.
