Unitree will sell you a massive 'transformable mecha' for $650,000

"“It can transform. It's a civilian vehicle. It weighs ~500kg with you inside,” Unitree says in the video description. “Please everyone be sure to use the robot in a friendly and safe manner.”"

"Unitree shows it knocking over a wall of cinderblocks and switching between bipedal position (which, to me, resembles the Power Loader that Ellen Ripley pilots in Aliens) to a mode that allows it to walk around on four legs like an unsettling mechanical horse."

"Some shots show Unitree CEO Xingxing Wang clambering into the GD01's cockpit, what appears to be a racing-style chair surrounded by a roll-cage. I suspect, however, that the “passenger” it's actually seen carrying around is likely a dummy for testing purposes. It's also unclear how the mech is actually operated as some clips show that it can perform tasks without having a person inside it."

"Its ability to “transform” - switching between bipedal and quadrapedal modes - also appears to be limited, as the seating position doesn't orientate itself when the bot flips over. Any passengers in this situation will either find themselves staring into the sky, or, presumably, having to get out and adjust the seat position manually."

Unitree has introduced the GD01, described as the world’s first production-ready manned mecha, priced at about $650,000. The provided demonstration shows the suit knocking over a wall of cinderblocks and switching between bipedal movement and a four-legged mode resembling a mechanical horse. The video description states the vehicle can transform, is civilian, and weighs about 500 kg with a person inside, with a request to use it safely. Footage shows a cockpit with a racing-style chair and roll-cage, though some scenes suggest a dummy may be used for testing. Operation details remain unclear, and seat orientation may not automatically adjust when switching modes.
