I noticed an interesting detail: Unitree Technology's newly released As2-W wheeled-legged robot uses a very plain scenario in its promotional video—it carries a box weighing about 16 kg and runs at a constant speed on the asphalt road within the park. No somersaults, no backflips, no fancy obstacle-crossing performances. This "restraint" is actually more worth dissecting than the specs.
Let's look at the hard metrics first. A speed of 6 m/s is roughly equivalent to 21.6 km/h, which places it in the first tier among hybrid quadruped+wheel forms. For comparison, Boston Dynamics' Spot has an official max speed of ...

This wheeled-legged solution reminds me of the dilemma of "multimodal fusion" in medical imaging—increasing mechanical complexity in exchange for improved scene adaptability. I want to ask if anyone has actually run this on rainy surfaces in a real park; have there been issues with the wheel hub motors after continuous rain exposure for half an hour under IP54 rating?
