B2 weighs 60 kg and is built for industrial environments. IP67 sealing protects it from dust, water and debris.
High-torque motors enable B2 to support itself and 40+ kg loads on slopes and uneven terrain without slipping or stalling.
The sensor suite enables autonomous hazardous-environment inspection—fire-damaged buildings, chemical plants—without human entry.
Extended battery life and efficient locomotion allow all-day inspection missions covering 15+ km per charge.
