Unitree B2-W Wheel-Foot Robot
Regular price
€0,00
Unitree B2-W is a wheel-foot robot in the Unitree B2-W series. It is designed for flexible movement over different terrains, including stairs, slopes, barricades, grass, stone, and gravel paths. It uses self-developed high-performance joints and combines perceptual and motor control to maintain balance on discrete terrains. The platform supports user development based on the Intel Core i7 configuration.
Highlights
- Maximum speed is 15 km/h in special configurations, with practical speed limits for security purposes.
- Maximum endurance is 25 km with a 40 kg load in special configurations.
- Maximum endurance without load is approximately 30 km.
- Maximum standing load is 120 kg.
- Walking load is greater than 40 kg.
- Maximum wheel torque is 40 N.m and maximum wheel speed is 50 rad/s.
- Ingress protection rating is IP67.
- Can continuously climb stairs of 20–25 cm and climb up and down stairs of 40 cm in the forward direction.
