Quadruped Robots
Robot Dogs: Complete Guide to Quadruped Robots
About 25,000 quadruped robots are deployed globally. They span five price tiers from $339 to well over $100,000. The right tier depends entirely on your use case — not just your budget.

Market snapshot
~25,000 quadrupeds deployed globally as of 2026. The largest segment is industrial inspection — robots that walk through environments where wheeled vehicles cannot go.
Five price tiers explained
Bittle is the reference product at $339. Open-source, programmable, and genuinely functional at small scale. Not suitable for any industrial task but excellent for learning robotics fundamentals.
Go2 Air starts at $1,600 direct from Unitree. US buyers pay $3,090 through resellers plus $400–1,000 in shipping and import fees — total landed cost $2,000–$4,500. Capable AI locomotion at this price is genuinely new as of 2024-2025.
The B2 and X30 carry meaningful payload, operate in outdoor environments, and can run 8+ hours on a charge. Used by universities, energy companies, and construction firms. Requires some integration work but does not need a dedicated robotics team.
Spot at $74,500 is the benchmark. Proven in extreme environments, with a full SDK and enterprise support. Payload options (Spot Arm, acoustic sensors, thermal cameras) add cost. Boston Dynamics sells to enterprises and government; individuals rarely qualify.
Vision 60 is primarily a defense platform. Procurement through government channels. Price is not publicly listed. Competing with Spot for DARPA and Air Force contracts. Not available to private buyers.
Import cost warning for US buyers
Unitree's published prices are ex-factory China. The Go2 Air lists at $1,600. US buyers purchasing through the official US reseller pay $3,090, plus $400–$1,000 in shipping and import duties. Total landed cost: $2,000–$4,500. Always calculate full landed cost before comparing to Spot or other US-stocked alternatives.
