~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

Hobbyist
$300 – $1,500
Petoi Bittle ($339)
STEM educationProgramming experimentsExhibition projects

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.

Consumer
$1,600 – $4,500
Unitree Go2 Air ($1,600 direct)
Personal explorationLight researchContent creation

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.

New 2025: Dobot Rover X1 at $1,030 — first credible sub-$1,100 capable quadruped. New entrant to watch.
Mid-range
$12,000 – $45,000
Unitree B2, Deep Robotics X30
Industrial inspectionConstruction site monitoringSecurity patrolResearch with payload

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.

Premium
$74,500 – $100,000
Boston Dynamics Spot ($74,500 base)
Oil and gas inspectionConstruction site documentationEmergency responseMilitary reconnaissance

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.

Enterprise / Defense
$100,000+
Ghost Robotics Vision 60
Military base securityBorder patrolClassified facility inspection

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.
