Unitree B2-W
The Unitree B2-W is an industrial wheeled quadruped robot for stairs, slopes and rough terrain, with a standing payload of 120 kg.
The B2-W combines the legs of a robot dog with wheels at the ends. According to Unitree the payload is 120 kg when standing and more than 40 kg while walking. Top speed is 15 km/h depending on configuration, and range is up to 25 km with a 40 kg load. The robot weighs about 85 kg including battery (over 2 kWh at 58 V), climbs 20 to 25 cm stairs continuously and can take a slope of more than 45°. The protection class is IP67 and the temperature range −20 to 55 °C. Unitree states that part of the functions need human operation or secondary development and that top speed is limited in practice for safety reasons. It is a civilian robot. Availability in the Netherlands is not confirmed.
