Best robot dogs (quadruped robots): rankings, specs and prices

14 robot dogs (quadruped robots) ranked from 25 we track, using the evidence method behind the Robot 500 (v2.0): sourced performance compared only with other robot dogs (quadruped robots) (70%), plus real-world proof such as sales, deployments and certifications (30%). Price is not part of the rank. 6 of them can be ordered now. Nobody can pay for a position, and we don't earn from the links on this page.

Ranked on published evidence, not hands-on testing: it measures sourced specs and real-world proof, not AI quality, reliability or how a demo looks. Robots still in development are listed under "Not ranked yet". Scores less than 1 point apart share a position (=). Every figure links to its source on the robot's spec page.

Quick answers

What is the best robot dog ?

On published evidence, the Unitree B2 ranks first of 14 ranked robot dogs (quadruped robots) (score 64.1/100, evidence grade B). The ranking weighs sourced performance figures and real-world proof; it is not a hands-on test. Full list: https://rankedrobot.com/best/quadruped-robots/

Which robot dogs (quadruped robots) can you buy now?

6 of the ranked robot dogs (quadruped robots) are shipping or open for pre-order. The highest-ranked is the Boston Dynamics Spot (Shipping).

How does RankedRobot rank robot dogs (quadruped robots)?

Only against other robot dogs (quadruped robots). Score = 70% performance (sourced specs as percentiles against category peers, weighted by source and pulled towards the average when evidence is thin) + 30% real-world proof (on sale, deployments, certifications, independent data). Price is kept out of the rank; the lowest published price is shown separately. Every rank carries an evidence grade, and robots with too little evidence are not ranked. Criteria are frozen for the current edition and no maker can pay for a position. https://robot500.com/methodology/
