Security Robots

One of the most widely deployed autonomous security robots in the United States. The Knightscope K5 is a five-foot-tall, 400 lb wheeled platform equipped with 360-degree cameras, thermal imaging, LiDAR, and licence plate recognition. It patrols autonomously along pre-programmed routes and detects anomalies such as unusual sounds, unrecognised people, or environmental hazards. Deployed at shopping centres, hospitals, corporate campuses, and parking structures. Offered as a Robot-as-a-Service (RaaS) subscription at around $6-$9 per hour — less than the cost of a human security guard.

Knightscope's heavy-duty, four-wheeled outdoor security robot built for long-range perimeter patrol across miles of fence lines, airport runways, military bases (defensive role only), and industrial zones. The K7 handles gravel, grass, and uneven surfaces that would stop a K5, and carries an extended sensor suite including high-resolution cameras, licence plate readers, and environmental sensors. Designed for 24/7 operation in all weather conditions, with automatic return-to-base charging. Available on the same RaaS subscription model as other Knightscope platforms.

Indoor security robot platform that combines autonomous patrol with a human-in-the-loop operations centre. Cobalt robots navigate office buildings, data centres, and corporate facilities using a sophisticated sensor suite that includes HD cameras, environmental sensors (smoke, gas, temperature), badge readers, and people counters. When the robot detects an anomaly, a trained Cobalt specialist reviews the situation remotely and can speak through the robot's two-way audio. Integrates with existing access control and visitor management systems. Clients include Fortune 500 companies and major tech campuses. Offered as a managed service.

Russian-designed autonomous outdoor security robot purpose-built for 24/7 perimeter patrol in harsh conditions. The S5.3 Argus carries dual thermal and visible-spectrum cameras, a PTZ (pan-tilt-zoom) turret, and optional ANPR (automatic number plate recognition). Its heavy-duty chassis handles rain, snow, and temperatures from -40 to +50 °C. A single operator can manage a fleet of dozens of units from one command dashboard, making it highly scalable for airports, solar farms, power stations, and logistics parks. GPS-guided waypoint patrol with automatic obstacle avoidance.

Integrates with smart home devices via voice and IFTTT. A charming gateway into home robotics for around $250, with optional subscription for advanced AI features.

A complete autonomous drone security ecosystem from the Swiss-American company Sunflower Labs. The system combines ground-based motion and vibration sensors (the "Sunflowers") planted around the property perimeter with an autonomous drone (the "Bee") that launches from a weatherproof base station (the "Hive") to investigate alerts. The drone carries thermal and visible-light cameras, streams live video to a security dashboard or smartphone, and returns to recharge automatically. No pilot required — the system operates fully autonomously, making it one of the most hands-off aerial security solutions available. Designed for large residential estates, vineyards, commercial properties, and luxury developments. Pricing is typically in the five-figure range for full installation.

Enterprise-grade autonomous drone security platform that combines drone-in-a-box hardware with AI-powered flight planning and real-time analytics.
