AgiBot D1 Series
The AgiBot D1 Series, branded Kutuo, is the industrial quadruped family of the world's highest volume robot maker, spanning the compact D1 Pro, the inspection flagship D1 Ultra with its 3.7 metre per second speed, 35 centimetre vertical jump and 200 hour extreme condition rating, the high payload D1 Max Pro, the wheeled D1 Ultra W and D1 Max wheeled variants and the all terrain D2 Max above them, all running reinforcement learning locomotion within AgiBot's unified intelligence ecosystem.
AgiBot D1 Series
When the maker of the world's largest humanoid fleet decided robots also needed four legs, it named the result after the idea of opening ground. The AgiBot D1 Series, branded Kutuo, is the industrial quadruped family of AgiBot, the world's highest volume robot maker: a ladder of robot dogs built for security inspection, survey exploration, emergency response, data collection and research across terrain where wheeled platforms stall and bipeds spend their effort balancing. Its inspection flagship, the D1 Ultra, states the family's character in figures: 3.7 metres per second with a limit near 5, 35 centimetre vertical jumps, slopes past 30 degrees, and a rated 200 hours of stable operation in extreme environments.
The series' real distinction, though, is what it plugs into. Every Kutuo machine runs inside AgiBot's unified embodied intelligence ecosystem, the same stack that powers the maker's humanoids, which turns a robot dog purchase into a fleet decision: one vendor, one intelligence platform, one developer surface from biped to quadruped, with the family's athletic ceiling on public display, parkour runs and ring battles, at AgiBot's i-City AI World Experience Centre in Malaysia, opened in January 2026. Six machines now carry the line: three legged, two wheeled, and the all terrain D2 Max above them all.

Background
Why the humanoid leader built dogs
AgiBot, founded in Shanghai in February 2023 and ranked the world's number one robot maker by shipment volume, positions its portfolio as general purpose embodied robots and their application ecosystems, and quadrupeds close a gap no humanoid fills: the outdoor, uneven, stair broken and rubble strewn ground where four legs are simply the correct answer. The D1 Series gives AgiBot standardised organisations their terrain division, patrol routes, field surveys, response missions, without leaving the maker's intelligence stack, and gives the stack itself a harder classroom, locomotion learnt on ground that punishes mistakes.
A ladder with wheels on two rungs
The family is structured by mission weight. The D1 Pro opens the line compactly; the D1 Ultra carries the industrial inspection brief with the series' published benchmark set; the D1 Max Pro raises payload and endurance for the hardest field work; and two wheeled variants, the D1 Ultra W and the D1 Max wheeled, add rolling transit to the Ultra and Max tiers for routes that mix distance with terrain, connecting the series into the wheeled quadruped tier. Above the D1 designation, the all terrain D2 Max extends the ladder's reach further still.
The D1 Series Lineup
AgiBot D1 Pro
The D1 Pro is the family's compact opener: an agile platform for dynamic locomotion, demonstration, education and light inspection duties, the accessible entry into the Kutuo ecosystem and a natural first quadruped for programmes that will grow into the tiers above it.
AgiBot D1 Ultra
The D1 Ultra is the series' published proof. Twelve degrees of freedom, three per leg, drive running speeds of 3.7 metres per second with a limit near 5, vertical jumps of 35 centimetres, slopes beyond 30 degrees and continuous 16 centimetre stairs, under an embedded reinforcement learning motion algorithm that reads and adapts to surfaces autonomously. Its ruggedisation is specified rather than implied: IP54 protection with sealed key components and anti corrosion treatment for splash, damp, mud and sand, rated for 200 hours of stable operation in extreme conditions. It carries 8 kilogramme static payloads to a 10 kilogramme limit, ranges 6 kilometres unloaded at 1.8 metres per second or 4 kilometres under 5 kilogrammes, and expands through modular 3D LiDAR, depth camera, RTK and 4G options over Ethernet and USB, with Isaac Sim, MuJoCo and open SDK support for developers.
AgiBot D1 Ultra W
The D1 Ultra W wheels the flagship: the Ultra's platform, athletics and ruggedisation with rolling transit added for the kilometres between inspection points, the series' answer where routes mix estate roads and plant floors with the stairs and slopes that justified legs, wheel variant configuration confirmed at quotation.
AgiBot D1 Max Pro
The D1 Max Pro is the heavy fielder: the series tier built for demanding payload, endurance and field use beyond the Ultra's brief, carrying the Kutuo line into missions where equipment loads and route lengths climb together, specifications confirmed at quotation.
AgiBot D1 Max Wheeled
The D1 Max wheeled completes the hybrid pair at the series' heavy end: the Max tier's payload and endurance on rolling feet, the machine for AgiBot standardised fleets whose cargo crosses real distances, configured at quotation.
Above the Series: AgiBot D2 Max
The all terrain D2 Max stands above the D1 family as the Kutuo range's furthest reach, extending the same ecosystem to the roughest ground in the catalogue, the ceiling the D1 ladder climbs toward.

Which D1 Series machine suits which buyer?
Match tier to mission, then configuration to route. Programmes entering legged robotics, classrooms and demonstration fleets start at the D1 Pro. Security inspection rounds, survey work and target tracking missions take the D1 Ultra, the tier whose 200 hour extreme rating was written for exactly that duty, choosing the Ultra W where long easy distances separate the hard sections. Heavy equipment carries and extended field campaigns take the D1 Max Pro, wheeled where the map says so, and the roughest territory looks above the series to the D2 Max. The decisive factor for many buyers is the ecosystem: organisations running AgiBot humanoids gain a quadruped division on the intelligence stack they already operate, one developer surface and one vendor relationship across standard and wheeled configurations alike, with cross brand mission software, RoboPatrol and RoboInspect class systems from the robot software catalogue, coordinating above.
Technology
Locomotion that learnt the ground
The series moves on embedded reinforcement learning: gaits trained rather than programmed, adapting autonomously to the surfaces underfoot, tarmac, gravel, wet stone, stairs, and extending to the athletic ceiling the family demonstrates publicly, parkour and ring battle routines that are marketing on stage and stability engineering everywhere else, because a machine that can land a jump can shrug off a stumble.
Ruggedisation as a specification sheet
Kutuo weatherproofing is itemised: IP54 ingress protection, sealed critical components, anti corrosion treatment for the damp, muddy and sandy environments field missions actually visit, and the 200 hour extreme condition operating rating that converts "rugged" from adjective to number, the honesty industrial buyers can procure against.
Sensing by mission, not by default
The series treats perception as configuration: modular 3D LiDAR, depth cameras, RTK positioning and 4G communications specified per deployment over standard Ethernet and USB interfaces, so a campus demonstrator, a survey unit and a remote patrol machine are one platform with three sensor bills, upgradeable as missions evolve.
An ecosystem that spans body plans
Development rides AgiBot's wider stack: open SDKs with Isaac Sim and MuJoCo simulation support for training before hardware, and membership of the unified intelligence ecosystem shared with the maker's humanoid lines, skills, tooling and fleet infrastructure crossing body plans, the research surface of the world's highest volume robot maker on four legs.
What is the AgiBot D1 Series used for?
- Security inspection: patrol routes and site rounds across security robotics, the D1 Ultra's declared home mission.
- Survey and exploration: field data collection over broken ground across inspection robotics.
- Emergency response support: reconnaissance across rubble and storm ground within emergency response robotics.
- Target tracking and following: autonomous pursuit and escort behaviours in operational and demonstration settings.
- Research and education: RL locomotion, simulation to hardware pipelines and quadruped studies across research and educational robotics.
- Entertainment and interaction: the parkour and ring battle repertoire across entertainment and exhibition engagements.
- Equipment carry at the Max tiers: field loads across distances, wheeled where the route allows.

Summary
The AgiBot D1 Series is the terrain division of the embodied AI era's biggest fleet: six Kutuo machines laddering from a compact opener through a flagship that documents its toughness in hours and its athletics in centimetres, to heavy tiers, two wheeled variants and an all terrain ceiling, all speaking the same intelligence stack as the humanoids beside them. It patrols, surveys, responds, teaches and occasionally performs parkour in front of paying audiences, and it turns the question "which robot dog" into the easier question "which tier", with wheels available where the map argues for them. As the quadruped family of the world's highest volume robot maker, the D1 Series stands as the ecosystem answer in legged robotics, and this page as the European starting point for joining it.
