Crazy how Unitree as a company started only 6 years ago. The Unitree Go1 was released in 2021. Within 3 years they have had such a mastery of Quadrupedal robotics they can produce robots possessing capabilities eclipsing that of any Western counterparts. Show how aggressively commercializing a dumbed down version which is basically a toy(Go1 at $1600 a pop), actually funds the development of industry leading products, at 150K USD each it's probably only reserved for industrial/military usage.
Based on the Unitree website, the B2-W has the following specs:
Weight: 75 Kg
Endurance: 50km with 40kg load, maximum static load is 120 Kg
Maximum speed: 20 km/h
Maximum trench jump: 2m
The video of the bot looks so good it almost looks CG from how agile it is.
