A wheeled quadruped platform for fast travel and obstacle handling in industrial environments

The B2-W wheeled quadruped robot targets scenarios where efficient movement on rollable surfaces (industrial areas, infrastructure, regular ground) is needed, while maintaining the ability to cope with constrained environments.

Like the B2, it is designed to operate in varied conditions and can be used for mobility, perception, and equipment integration tests.

  • Maximum speed: up to 15 km/h
  • Long-distance travel possible, including with a significant payload
  • Maximum static load (standing): up to 120 kg
  • Load while moving: > 40 kg
  • Continuous stair climbing: steps of 20 to 25 cm
  • Climb up/down (forward): steps up to 40 cm
  • Slope capability: > 45°

The platform is based on a control and perception setup built around an Intel Core i5 (platform functions) and an Intel Core i7 (user development). Optional configurations are available with Intel Core i7 and Jetson Orin NX. Perception relies on a sensor suite including 1 3D LiDAR, 2 depth cameras, and 2 optical cameras.

The power system uses a removable battery for stable and reliable supply, with quick replacement and the option to integrate an autonomous charging solution depending on requirements.
