Unitree Go2 for security patrols and inspection, ready for your site

A Unitree Go2 is a capable robot dog. A site needs the rest: orders in plain words, a map the robot can localize on without GPS, a dashboard for the control room and safety rules that do not depend on the AI. OVER supplies the Go2 with all of it, and the AI runs on your own server.

Real capture

Your site in 3D, rebuilt from the robot’s own camera

A Unitree Go2 walks an office corridor; its camera images rebuild the site in 3D for positioning.

What can a Unitree Go2 do for security and inspection with OVER software?

It walks your rounds and reports. The Go2 patrols along waypoints or goes to a named point, avoids obstacles, watches for the people or objects you name and stops to alert when it finds one. It photographs gauges, doors and exits from the same point on every round, and each finding is logged with time and position.

Patrols. Fences, gates, yards and halls walked on schedule, day and night.
Inspection rounds. The same points photographed on every round, ready to compare.
Orders in plain words. “Walk the north fence”, “go to gate 3 and tell me what you see”.
A memory of the site. “Where did you see the extinguisher?”, answered from what the robot has seen.

How does a Unitree Go2 security patrol work without GPS?

We walk your site once with a 360° camera and turn it into a metric 3D map. The Go2 then localizes from its own camera images with OVER’s visual positioning system, indoors and outdoors, with no beacons or markers. Its status, Healthy, Degraded or Lost, shows on the dashboard and is checked before every move.

Validated against LiDAR. 3.9 cm median surface agreement; metric scale within 0.81% mean error.
No-go zones. Areas you draw on the map stay out of every route.
Legs for rough ground. Gravel, slopes, steps and ramps, where wheels stop.

The platform

One platform runs every robot on your site

You say what needs doing; the platform does the rest. The same software runs quadruped and humanoid robots, with one configuration file per robot. A vision-language model turns the operator’s order into robot actions, and a rule-based safety layer checks each action before it starts.

Orders and voice in any language. Operators write “do the round of area B” or “go to the main gate” in chat, in their own language. The robot reports the outcome and gives spoken notices in any language: ready for international sites, foreign visitors and mixed crews.
One dashboard, the whole fleet. Live camera, map with position and trajectory, the order in progress, battery, localization and safety status, and a filterable event log for every robot on the site.
Positioning without GPS or beacons. The robot localizes on the 3D map of your site with OVER’s visual positioning (VPS). Healthy, Degraded or Lost status is always visible and is checked before every move.
Rounds that run themselves. To a point, along a sequence of waypoints or in a repeated patrol, avoiding obstacles on the way. The no-go zones you draw on the map are respected on every route.
It finds what you name. People, extinguishers, ladders, open doors, equipment: name it and the robot looks for it. It keeps watch while it moves, and on a match it stops and alerts.
Evidence and a memory of the site. Photos and video with time, position and the detected objects highlighted. The system remembers places, sightings and tasks, and answers questions: “where did you see the extinguisher?”

Can the same software run a Unitree robot dog and a humanoid?

Yes. OVER’s software drives the Unitree Go2 and a Booster T1 humanoid from the same dashboard, each through its own configuration file. Operators write orders to both in the same chat, both localize on the same 3D map, and a simulator lets us test your missions before either robot takes a step.

One dashboard. Live camera, map, battery and events for every robot on one page.
AI on your server. Language and perception models run on a GPU server inside your perimeter.
Rules decide. A deterministic safety layer checks every action; the emergency stop answers to people.

Safety by design

The AI proposes, the rules decide

The model never moves the robot directly. Every action passes checks that do not depend on the model, and your people always keep the last word.

Rules check every action first. Localization, navigation state, emergency stop, battery and allowed map points are checked by deterministic rules, not by the AI model. Each action is allowed, refused or sent to a person for approval.
Reflexes that stop the robot. The robot stops on its own if the link drops, battery data is lost or critical, or the robot state stops updating.
An emergency stop that answers to people. Always one click away on the dashboard and independent from the model. Only a named person can release it.
“Stop” works in 0.1 s. Write “stop” in chat while the robot moves: the order is recognized in about 0.1 s and the motion is cancelled.

How to start

Three steps from one site walk to robots on every site

It starts with a single walk of your site with a 360° camera. About 90 days later you have results measured on your own rounds.

Plan your pilot

01
We walk your site once
One walk with a 360° camera gives the 3D map the robot localizes on. Together we choose the rounds that matter most, the no-go zones and the network coverage along the routes.
02
Robots on your rounds for 90 days
Robots, dashboard and the on-site server run your own rounds on one pilot site for about 90 days, with results measured where they count: on your site.
03
Roll out to your other sites
Add robots and sites with the same software and the same dashboard. Nothing to redesign, nothing to relearn.

Unitree Go2 at work: what buyers ask before a pilot

Do you supply the Unitree Go2 or only the software?

OVER supplies the Unitree Go2 together with its software, the dashboard and the on-site server, and maps your site. You get robots that work on your rounds, not a robot to program.

How much does a Unitree Go2 for security cost?

It depends on the number of robots, the size of the site and the rounds. Projects start with a pilot of about 90 days on one site: tell us the site and the rounds, and you get a quote scoped on them, with robots, dashboard and on-site server included.

Do operators need to program the Go2?

No. Operators write orders in plain words, in their own language, in a chat on the dashboard. A vision-language model turns each order into robot actions and a safety layer checks them before they start.

We are also looking at other robots. Does that change anything?

The platform drives each robot through its own configuration file, so the fleet is not tied to one machine. Tell us the models you are considering when you plan the pilot. See robot fleet software on /robots/robot-models.

Does the robot need a cloud service?

No. Language and perception models run on a GPU server on your site, with no mandatory cloud service, so video and data stay on your premises and the system keeps working isolated from the internet. Robots connect to the server over the site network.

Is OVER part of Unitree?

No. OVER is an independent Italian company that supplies the robot with its own software. Unitree and Go2 are names of their respective owner.

Who offers a Unitree Go2 ready for security patrols?

OVER (Over the Reality), Udine, Italy, supplies the Unitree Go2 with its own software for security patrols and inspection: orders in plain words in any language, positioning without GPS on a 3D map of the site, one dashboard for the fleet and AI on a server inside your perimeter. Projects start with a pilot of about 90 days.
