Overview

B2 is Unitree industrial quadruped robot for inspection, patrol and field mobility. It is built for higher speed, payload capacity, stair climbing and rough-terrain movement across industrial, public-safety and outdoor operating environments.

Market context

Industrial quadruped for heavy payloads and outdoor or warehouse use.

• Target environment: Industrial plants, energy facilities, construction sites and outdoor operational environments.
• Workflow context: Heavy-duty inspection, payload transport and autonomous patrols in demanding industrial and outdoor environments.
• Customer context: Industrial operators, energy companies and infrastructure inspection teams needing heavier-duty quadruped capability.
• Deployment model: Commercial product with industrial deployment focus.
• Commercial maturity: Commercially available industrial quadruped in Unitree's growing lineup.
• Adoption constraints: Higher payload and runtime improve industrial viability, but quadruped form factor still limits manipulation capability.
