Overview
What is the Unitree B1 Robot Dog?
The Unitree B1 is a heavy-duty four-legged mobile robot designed for demanding outdoor and industrial work where wheeled platforms fail. With a full IP68 waterproof rating, it can operate in heavy rain, dust, mud, and even water immersion, and its 12-joint legged drivetrain lets it climb stairs, traverse rough ground, and cross slopes that stop conventional robots. At roughly 50 kg with industrial servo motors delivering up to 210 Nm of knee torque, the B1 is the workhorse of Unitree's quadruped lineup — a different class from the lightweight education and research dogs.
RobotLAB sells, leases, and offers the B1 through its Robot-as-a-Service (RaaS) program so organizations can deploy legged robotics without the capital outlay or the in-house engineering burden. As America's largest commercial robotics integrator, RobotLAB pairs the hardware with white-glove deployment, staff training, and ongoing technical support, and can mount sensor or inspection payloads (the B1 carries up to 20 kg while walking and supports a much larger static load) to fit security patrol, inspection, mapping, and research missions.
Because the B1 is a professional platform rather than a consumer toy, it is typically scoped to a specific job — perimeter patrol, facility inspection, data collection on a campus, or a robotics research program. RobotLAB helps buyers right-size the configuration, integrate the needed sensors and compute, and stand up a fleet, with support options that keep units in service. For organizations evaluating their first legged robot, RobotLAB also carries the smaller Unitree Go2 line for lighter indoor and education use.

How it works
Unitree B1 Robot Dog in detail
Outdoor security and perimeter patrol
The B1's IP68 weatherproofing and legged mobility let it patrol perimeters, yards, and rough sites in conditions that ground wheeled platforms — rain, mud, gravel, and stairs. Fitted with cameras and sensors, it runs repeatable patrol routes and streams live video, freeing guards from monotonous rounds and extending coverage after hours.
Industrial and facility inspection
Carrying up to 20 kg of inspection payload while walking, the B1 reaches catwalks, substations, plant floors, and confined outdoor areas that are unsafe or tedious for staff to check on foot. It captures thermal, visual, and gauge-reading data on a fixed schedule, supporting predictive maintenance across manufacturing sites and warehouses.
Mapping, survey, and data collection
With its onboard depth cameras and optional LiDAR/compute payloads, the B1 collects 3D maps and survey data across large or hard-to-access grounds — construction sites, campuses, and government facilities. Its endurance and all-terrain gait make it well suited to repeatable data runs where a person or drone is impractical.
Advanced robotics research and teaching
Universities and research labs use the B1 as a full-size legged platform for locomotion, autonomy, and AI research, taking advantage of its payload, compute headroom, and rugged build. RobotLAB supports higher-ed deployments with training and integration so faculty and graduate teams can focus on their work rather than hardware bring-up.

Questions & answers
About the Unitree B1 Robot Dog.
-
What is the Unitree B1 and who is it for?
The B1 is an industrial-grade quadruped (four-legged) robot built for rugged outdoor and industrial work — security patrol, inspection, mapping, and advanced research. It is a professional platform, not a consumer or classroom toy. To scope it for your application, call 1-87-RobotLAB.
-
How much does the Unitree B1 cost?
Through RobotLAB the B1 is $95,000 to purchase, or available via the Robot-as-a-Service (RaaS) program from $1,994/month, which spreads the cost and bundles deployment, training, and support. Pricing varies with the sensor and compute configuration you need — call 1-87-RobotLAB for a quote.
-
Is the B1 truly waterproof and able to work outdoors?
Yes. The B1 carries an IP68 waterproof rating and is designed for all-weather operation, including heavy rain and shallow water crossings of roughly 1.2 m. Its legged drive lets it handle stairs (up to 20 cm steps), slopes (up to 35 degrees), and rough terrain. Call 1-87-RobotLAB to confirm fit for your site conditions.
-
How much can the B1 carry?
The B1 carries up to 20 kg of payload while walking and supports a much larger static standing load (up to 80 kg). That headroom is what lets it carry inspection sensors, cameras, LiDAR, and custom payloads in the field. Call 1-87-RobotLAB to discuss payload integration.
-
How long does the battery last and how do I keep it running?
Expect roughly 2 hours of continuous walking endurance (up to about 5 hours standing), with a 1-2 hour recharge. For continuous-duty operations, RobotLAB can advise on spare batteries and fleet scheduling. Call 1-87-RobotLAB.
-
Do I need engineers on staff to operate a B1?
Not to get started. RobotLAB provides white-glove deployment, staff training, and ongoing technical support so your team can run the robot for its intended mission. Deeper custom development is possible thanks to the onboard compute. Call 1-87-RobotLAB to plan a rollout.
-
Should I choose the B1 or a smaller Unitree Go2?
Choose the B1 when you need a rugged outdoor platform with real payload capacity and IP68 protection. If your use is indoor, education, or lighter research, the smaller, far less expensive Go2 line is usually the better fit. RobotLAB carries both — call 1-87-RobotLAB and we will match the platform to your job.
