B2 FAQ

B2 is designed for heavy-duty environments—industrial inspection, infrastructure patrol, logistics over uneven terrain, even remote/harsh sites. With its high mobility, heavy payload capacity and dual leg/wheel options, it offers flexible field readiness

Yes — with a heavy payload budget (standing 120 kg) and support for various configurations (leg + wheel, rugged terrain), B2 supports custom sensor modules, cameras, LiDAR, robotic arms, etc. Ensure total payload + robot weight remains within spec and check connector/interface options.

The wheeled-leg variant adds wheels to each leg, improving efficiency on flat surfaces while retaining legged mobility for obstacles. This enables hybrid mission profiles: legged for stairs/complex terrain, wheeled for speed/efficiency.
