Security and inspection robots take over rounds that are dull, dangerous or happen at night. There are two main types. Quadrupeds such as Boston Dynamics Spot, ANYbotics ANYmal D or Unitree B2 walk over stairs, gravel and pipes and carry thermal cameras and sensors through plants and substations. Wheeled patrol robots such as Knightscope K5 or SMP Robotics S5.2 drive around parking lots and perimeters, while Cobalt Robot patrols offices from the inside.
Before buying, decide where the robot will work and what it has to detect. Outdoors, look at the IP rating, operating temperature and runtime per charge; wheeled patrol robots like SMP S5.2 usually last much longer than legged ones. Oil, gas and chemical sites need explosion-proof certification, which ANYmal X and Taurob Inspector V8 have. Also check payload for extra sensors, docking with auto-charging and how alerts reach your security team.
Our catalog has 18 models from 10 brands in 4 countries. 8 of them have a published price, from $1,600 for an entry-level quadruped to $375,000 for a fully equipped industrial unit. Inspection systems such as Spot or ANYmal are often sold through the manufacturer's sales team, so the final price comes in a quote.

Published prices run from $1,600 to $375,000. Consumer and education quadrupeds like Unitree Go2 sit at the low end, while industrial inspection models with sensors and a docking station cost many times more. Many vendors, including Boston Dynamics for Spot, sell through their sales team rather than a fixed price list.
Quadrupeds handle stairs, gratings and rough ground, so they suit plants, substations and industrial sites. Wheeled patrol robots are simpler and run longer per charge, which fits parking lots, campuses and long perimeters. Hybrids like Unitree Go2-W and B2-W put wheels on the legs to cover flat ground faster and still step over obstacles.
Only models with the right certification. ANYbotics ANYmal X is ATEX and IECEx certified for Zone 1, and Taurob Inspector V8 is built for ATEX Zone 1 at oil, gas and chemical plants. Check the exact zone and gas group for your site with the vendor.
Yes, though most models here are built for outdoor or mixed use. Cobalt Robot is an indoor robot for offices and campuses that works with elevators and access control. Smaller quadrupeds like Unitree Go2 or DEEP Robotics Lite3 also work indoors, but they are research and education platforms rather than ready security products.
Some vendors offer it: Cobalt Robot, for example, is sold as Robot-as-a-Service. For other models, leasing or subscription depends on the manufacturer and the country. Ask about it in your quote request.
