Kawasaki Kaleido 9 vs Persona AI Humanoid

Kawasaki Kaleido 9 is a 190 cm, 99 kg bipedal industrial humanoid prototype, publicly unveiled at iREX 2025 and still in the testing phase. Humanoid.guide lists a stated 30 kg payload, up to 5 km/h speed, and up to 3 hours runtime, but Robot Overflow conflicts on several specs and says Kawasaki has not published official battery or speed figures. A textual disaster rescue description says it gently picked up a toy cat, and Humanoid.guide confirms walking stairs and sorting goods as capabilities, with low manipulation and navigation scores. Current autonomy is not demonstrated; VR headset teleoperation is listed, and Ground News reports a 2030 plan for full autonomy using Noetra physical AI. The robot is not for sale and has no commercial deployment or named customer

Persona AI Humanoid is a first-generation industrial humanoid prototype from Persona AI (Houston) targeting shipyard welding, fabrication, construction, and energy. It has no published height, weight, payload, runtime, or speed. Evidence includes official claims of modular design and NASA-derived robotic hand technology, an agreement with HD Hyundai for shipyard robots with delivery expected within 18 months, an ABS MOU, and a Louisiana/SSE Steel pilot. The only direct demo evidence is an official video title 'Hand on the Torch: Gen 1 Welds in a Real Industrial Environment'; teleoperation status is not disclosed, and a directory headline reports a teleoperated welding demo. Autonomy is not demonstrated; the company states teleoperation precedes autonomy. No price or RaaS terms are available
