~$100k

The industrial quadruped — 40 kg+ payload, IP-rated, all-terrain endurance for heavy industry, agriculture, and inspection.

Industrial quadruped·for Heavy industry, agriculture, patrol, inspection

Specs

What it actually does.

Spec sheet

Weight (with battery)
≈ 60 kg
Payload (sustained walk)
40 kg+
Payload (max static)
120 kg
Top speed
≈ 1.6 m/s (loaded)
Battery life (active)
4–6 hours
Sensors
4D LiDAR, depth cameras, IMU

Use cases

  • Industrial inspection in hazardous environments
  • Agriculture monitoring (livestock, crops, perimeter)
  • Patrol and security in outdoor / unstructured terrain
  • Heavy-payload carriage on construction and energy sites

Honest callouts

  • · The B2 is built for sustained work. Treat it like an industrial sensor platform, not a demo.
  • · 40 kg sustained payload is the working number; 120 kg static is a max — not a recommended continuous load.
  • · All-terrain is real (it'll walk a rocky slope), but it's not an excavator. Choose the right tool for the right job.
