AgiBot D1 Max Wheel-Leg Quadruped Robot

The D1 Max is the industrial member of the D1 family, and the specification that separates it from every other robot on this page is payload: 25 kg rated, on a chassis that weighs only 41 kg itself, which AgiBot markets as a near 1:1 load-to-weight ratio and roughly a 50% improvement on comparable machines. It runs an embedded reinforcement-learning motion model with impact resistance, disturbance rejection, self-righting after falls, and dynamic self-adaptation, and it carries a full perception suite of vision, LiDAR, ultrasonic, and IMU sensors for environmental reconnaissance, autonomous navigation, and target recognition.

The second thing that sets it apart is the drivetrain. The D1 Max switches intelligently between wheel mode and leg mode, wheels for stable, efficient, long-endurance movement on flat ground, legs for terrain that defeats wheels. Combined with dual hot-swappable batteries, that is what makes it deployable on a real inspection route: over 5 hours of endurance and 29 km of range unloaded, and a stable 3.5 hours with 18 km under rated payload. IP67 protection means it works outdoors and in industrial environments all year.

Key Highlights

• 25 kg rated payload on a 41 kg chassis, with Gigabit Ethernet, USB and serial communication plus a 5V/12V/24V/48V, 480 W power interface for deep industrial integration.
• Wheel and leg mode switching: wheels for efficient distance, legs for terrain, selected intelligently rather than manually.
• 6 m/s maximum wheel speed for fast response and broad route coverage.
• Rated -20°C to 55°C, which is what separates it from the IP54 D1 models and makes winter deployment realistic.
• IP67 rated for long-term outdoor and industrial operation, reducing downtime and maintenance cost.
• Dual hot-swappable batteries (504.9 Wh × 2), so the robot returns to service without waiting on a charge cycle.
• Over 5 hours endurance and 29 km range unloaded; 3.5 hours and no less than 18 km under rated payload.
• 45° maximum climbing angle, 25 cm continuous stair climbing, and 80 cm obstacle crossing.
• Full perception suite, vision, LiDAR, ultrasonic, and IMU, supporting autonomous navigation and target recognition.
• Verified US equipment authorization under FCC ID 2BTPT-ZYCXD125M.
• Self-rights after falls and rejects disturbance, validated for high-intensity deployment.

The Industrial Inspection Configuration

AgiBot builds the D1 Max into a packaged inspection solution, and it is worth quoting that way rather than as a bare chassis. The configured system runs 50+ general inspection algorithms with five-gas detection covering O₂, CO, SO₂, CH₄ and SF₆, and it is the configuration the accuracy figures below apply to.

Standard configuration: dual-spectrum gimbal, gas detector, LiDAR.
Optional: robotic arm, partial discharge detector, acoustic signature sensor.

AgiBot also offers wireless bridge and 5G communication modules on this platform. We do not quote radio accessories until they carry their own US equipment authorization, so ask us and we will tell you exactly where that stands before you design a comms plan around it.

The software side is what makes it a route rather than a demo: offline mission planning, a three-axis stabilized gimbal, starlight night-vision camera, partial discharge monitoring, inspection result analysis, and a real-time monitoring display. AgiBot reports roughly double the operational efficiency of manual rounds and about half the delivery cycle time from offline mission planning.

The Security Patrol Configuration

The same chassis is also packaged as a patrol robot, and it is a different sensor set from the inspection build. Patrol adds a microphone, a long-range LiDAR, a binocular gimbal, a warning strobe light and a thermal imaging camera, and the D1 Max patrol solution supports autonomous following, which the smaller D1 Ultra patrol build does not.

Patrol software covers autonomous patrolling, autonomous obstacle avoidance, broadcast and intercom, video surveillance, image capture, facial detection, license plate detection, no-parking zone recognition, anomaly alerts and generated patrol reports. Inspection data is stored in a structured format, so a route can be replayed and audited after the fact rather than existing only as video.

Note the protection rating. The bare robot is IP67, the configured inspection build is IP66 and the configured patrol build is IP55, because the mounted payload sets the rating rather than the chassis. Specify the environment you are deploying into and we will confirm which build actually meets it.

Built For

• Industrial inspection routes: meter reading, defect detection, and abnormal temperature sensing
• Security patrol, threat inspection, on-site management, and critical point deployment
• Energy and utility sites where a payload has to be walked to places vehicles cannot reach
• Logistics and materials handling that need 25 kg carried over terrain rather than pavement
• Plant, refinery, and substation operators replacing manual rounds with a repeatable robotic route
• Integrators building a custom sensor or manipulator payload on a proven mobile base

Good to Know

• Rated load is 25 kg, and that is the figure every endurance and range number here is based on. Ignore any larger payload figure you may see quoted elsewhere unless AgiBot confirms it in writing for your configuration.
• Wheel mode delivers the range and efficiency numbers; leg mode trades endurance for terrain capability. Route planning should account for the mix.
• The robot is IP67. The complete industrial inspection package, with the gimbal and sensors mounted, is rated IP66, and the patrol package is rated IP55. Mounted third-party payloads carry their own ratings, so check the whole stack rather than just the chassis.
• At 41 kg moving up to 6 m/s, this is an industrial machine. Site safety procedures, trained operators, and exclusion zones are appropriate.
• Charging docks, spare batteries, and sensor payloads are quoted separately. Tell us the route and we will spec the whole deployment.

How Purchasing Works

The D1 Max is quoted per deployment rather than sold from a cart, because payload, sensors, charging, and spares change the answer. Send us the site, the route, and what the robot needs to carry, and we return a formal written quote, typically the same or next business day. We support purchase orders from utilities, municipalities, public agencies, and enterprise procurement, and we accept tax-exempt purchasing with a valid certificate on file.

Frequently Asked Questions

How much does the AgiBot D1 Max cost?
The D1 Max is $42,999 before payloads and accessories. Deployments are quoted individually because sensors, charging, and spares vary by site.

Is the AgiBot D1 Max authorized for use in the US?
Yes. It carries FCC ID 2BTPT-ZYCXD125M, granted before the FCC's 28 July 2026 rule change. You can verify it directly in the FCC's equipment authorization database at apps.fcc.gov/oetcf/eas. Note that FCC equipment authorization is separate from NDAA procurement eligibility, which is a different question for federally funded buyers.

How much can it actually carry?
Rated load is 25 kg on a 41 kg chassis, and that is the figure the endurance and range specifications are based on. AgiBot markets this as a near 1:1 load-to-weight ratio and about a 50% improvement over comparable machines.

What is the difference between the inspection and patrol configurations?
Different payloads on the same robot. The inspection build carries a dual-spectrum gimbal, gas detector and LiDAR, runs 50+ inspection algorithms with five-gas detection, and is rated IP66 configured. The patrol build carries a microphone, long-range LiDAR, binocular gimbal, strobe and thermal camera, adds autonomous following and patrol analytics, and is rated IP55 configured. Both run 2 hours or more over 20 km or more.

What is wheel and leg mode switching?
The D1 Max can roll on wheels or walk on legs and selects intelligently between them. Wheel mode gives stable, efficient movement with extended endurance on flat ground; leg mode handles stairs, rubble, and terrain that stops wheeled robots.

How long does it run per charge?
Over 5 hours unloaded and a stable 3.5 hours at rated payload, covering more than 29 km unloaded and no less than 18 km loaded. Dual batteries are hot-swappable, so the robot goes back out without waiting on a charger.

Can it work outdoors in bad weather?
Yes. The D1 Max is IP67 rated for long-term outdoor and industrial operation, and it is rated from -20°C to 55°C. Note that mounted third-party sensors carry their own protection ratings, and the complete inspection package is rated IP66.

Can it climb stairs?
