Fastest Robot Dogs

The twenty fastest four-legged robots (quadrupeds), ranked by top running speed. The list runs from lab sprinters that outran Usain Bolt to robot dogs on sale today. Each entry covers how fast it runs, how that speed was measured, what it weighs and what it costs. Some robot dogs are wheel-legged hybrids, with wheels on their feet, and roll faster than they run. Only running speeds count here.

Top 20 robot dogs ranked by top speed

Robots are ranked by the fastest speed reported for running on legs. Many figures are maker claims or special-mode peaks, and everyday rated speeds are often lower. Robots with the same figure share a step on the chart. Speed measurement methods explains the differences.

  1. 1Black Panther 2.0

    Black Panther 2.0

    Research robotTop speed 13.2 m/s (29.5 mph) on a treadmill, 11.65 m/s outdoorsWeight 36.5 kgPrice Not for sale

    A sprint quadruped from Zhejiang University and its spin-off Mirror Me. Springs at the knees and light carbon-fiber shins let it run like a greyhound. The team's September 2026 papers report 13.2 m/s on a treadmill and 11.65 m/s outdoors on concrete, with a best 100 m of 11.67 s.

    That treadmill figure passes the 2012 record of Boston Dynamics' Cheetah, and its outdoor speed is the fastest on this list. None of these runs has been certified, though. Early headlines of "100 m in under 10 seconds" were an estimate from treadmill speed. Mirror Me's consumer Black Panther X is the closest relative anyone can buy.

  2. 2Cheetah

    Boston Dynamics Cheetah

    Research robotTop speed 12.6 m/s (28.3 mph) on a treadmill, tetheredWeight Not publishedPrice Not for sale

    A hydraulic sprinter Boston Dynamics built for DARPA. In September 2012 it ran its fastest 20 m split at 28.3 mph, just past Usain Bolt's best. Like a real cheetah, it flexed its back with each stride.

    The record came with caveats. It ran on a treadmill, drew power from an off-board pump through a tether and was held centered by a boom arm. It held the legged-robot speed record for over a decade. It is unrelated to MIT's Mini Cheetah.

  3. 3WildCat

    Boston Dynamics WildCat

    Research robotTop speed ~7.2 m/s (16 mph) outdoors, untetheredWeight Not publishedPrice Not for sale

    The free-running successor to Cheetah, shown in 2013. A two-stroke go-kart engine drove its hydraulic pump, and a small fuel tank gave about five minutes of running. It bounded and galloped across a parking lot at about 16 mph.

    It was much slower than the tethered Cheetah but carried its own power. DARPA's goal for the program was a robot that could run 50 mph on any outdoor ground.

  4. 4White Rhino

    White Rhino

    Research robotTop speed ~6.1 m/s (13.7 mph) average over 100 mWeight Not publishedPrice Not for sale

    A heavy-duty Zhejiang University quadruped that holds the Guinness record for the fastest 100 m by a quadrupedal robot, 16.33 s, set in May 2025. The time includes a standing start, so its top speed is higher than the 6.1 m/s average. It beat the 19.87 s record of KAIST's Hound robot.

    The team says it can also carry up to 100 kg. Its stablemate Black Panther 2.0 has since run 100 m faster in the team's own tests, but those runs weren't certified.

  5. 5B2

    Unitree B2

    On saleTop speed 6 m/s (13.4 mph)Weight 60 kgPrice $85,000 – $180,000

    Unitree's large industrial quadruped and the fastest robot dog on sale. Its 6 m/s rating is Unitree's own figure. It also long-jumps over 1.6 m, clears 0.5–1.2 m ditches and climbs 20–25 cm stairs without stopping.

    It is built for inspection, rescue and research work in rough places, not for a home. The wheel-legged B2-W trades some of that legged speed for rolling efficiency.

  6. 6KAIST RAIBO2

    KAIST RAIBO2

    Research robotTop speed 6 m/s (13.4 mph) per the labWeight 42 kgPrice Not for sale

    A Korean research quadruped built for speed and endurance at once. Its lab quotes a 6 m/s top speed. In November 2024 it ran a full marathon on one charge in 4:19:52, averaging 2.64 m/s, with a human operator steering it.

    The work was published in Nature in September 2026. The spin-off Raion Robotics is preparing a commercial version for inspection and disaster work.

  7. 7Go2 EDU / EDU Plus

    Unitree Go2 EDU

    On saleTop speed ~5 m/s (11.2 mph) claimed, 3.7 m/s ratedWeight 15 kgPrice $11,190 – $15,600

    The developer version of the Go2, with an NVIDIA Jetson on board. Unitree rates it at 3.7 m/s in normal use, with a higher ~5 m/s maximum quoted.

    It is one of the most common research dogs. The cheaper Go2 Air and Pro run at 2.5 and 3.5 m/s.

  8. 8A2

    Unitree A2

    On saleTop speed ~5 m/s (11.2 mph)Weight 37 kgPrice $52,000 – $88,000

    Unitree's mid-size industrial dog, launched in 2025 between the Go2 and the B2. It is lighter than the B2 but nearly as fast, with a long range for patrol and inspection routes.

  9. 9FX Aegis (Pro / Edu / Ultra / Ultra-W)

    FX Aegis Ultra

    On saleTop speed 5.0 m/s (11.2 mph) for the Ultra, 3.7 m/s for the ProWeight 16 kgPrice $12,990 (Ultra)

    The Lite3's predecessor from 2021, and the first quadruped to perform a side flip. Its spec sheet gives a 3.75 m/s maximum with peaks over 4 m/s. It has been replaced by the Lite3.

  16. 16Black Panther X

    Mirror Me Black Panther X

    Kickstarter, not shipping yetTop speed 4 m/s (8.9 mph)Weight Not publishedPrice ~$1,200 – $1,500 (Kickstarter)

    A snap-together consumer kit from the team behind Black Panther 2.0. It runs at 4 m/s, well below its record-setting sibling, but carries 8 kg and can do a 720° flip. Kickstarter backers were promised deliveries from July 2026.

  17. 17MIT Mini Cheetah

    MIT Mini Cheetah

    Research robotTop speed 3.9 m/s (8.7 mph) measuredWeight ~9 kgPrice Not for sale

    MIT's small research dog from 2019, the first quadruped to backflip. Its original controller topped out at 2.45 m/s. A 2022 controller trained by reinforcement learning pushed it to 3.9 m/s, one of the few speeds on this list from a published, measured run.

  18. 18Vbot

    Vbot

    On saleTop speed ~3.9 m/s (14 km/h)Weight ~16 kgPrice ~$1,500 (¥9,988, China)

    A Chinese consumer companion dog that follows its owner without a remote. Vita Dynamics rates it at 14 km/h, and it can tow up to 100 kg. It is the cheapest robot in the top 20 that is on sale now, and it launched in Europe at IFA 2026.

  19. 19Steel Grit SG1

    Foxtech Steel Grit SG1

    On saleTop speed 3.7 m/s (8.3 mph)Weight ~20 kg (listed shipping weight)Price $5,672 – $23,172

    A 12-DOF research dog sold by Foxtech, with 48 N·m joints, IP54 sealing and a ROS 2 SDK. Its spec sheet closely matches Genisom AI's L1, so it may be a rebadged version (unconfirmed). It shares its 3.7 m/s rating with the Go2 EDU's everyday speed and the FX Aegis Pro.

  20. 20Go2 Air / Pro / X

    Unitree Go2 Pro

    On saleTop speed 3.5 m/s (7.8 mph)Weight 15 kgPrice $2,800 (Pro)

    Unitree's popular consumer robot dog, here in its $2,800 Pro version. The Pro runs at 3.5 m/s, while the $1,600 Air is limited to 2.5 m/s. Programming it needs the much pricier Go2 EDU or community tools.

    It ties at 3.5 m/s with the AgiBot D1 Pro and China Mobile's Lingxi.

Just outside the top 20, the DEEP Robotics Lite3 is rated at 2.5 m/s. Some listings quote up to 4 m/s, but those figures conflict with DEEP Robotics' own rating.

Speed measurement methods

Robot speeds are measured in very different ways, so close ranks are approximate.

Wheel-legged hybrids

Wheel-legged hybrids have wheels at the ends of their legs, and several roll faster than any of these robots can run. These wheel speeds aren't ranked above, since rolling isn't running. Astrall Hypertron-T01 reaches 7 m/s in lab tests, Tencent Max about 25 km/h on its knee wheels and the As2-W 6 m/s. The DEEP Robotics LYNX M20 reaches 5 m/s in lab tests (2 m/s in normal use), with no split between rolling and walking. The Lightyear M1 is rated at 5 m/s, the Unitree B2-W 15 km/h and the Rover X1 Pro Flex 3 m/s.
