T800's 450 Nm: what matters is after lifting all day

EngineAI laid out the T800's specs, and the most eye-catching is that 450 N·m peak joint torque, a 173 cm frame, 29 degrees of freedom not counting the dexterous hands. For heavy-load work, the direction is right. But I stared at that number for a long time, and the first question that popped into my head was: and then what.

I've been using a UR robotic arm for two months, and what really gives me headaches on the production line is whether it's still accurate after lifting all day. Peak torque is nice for a one-off demo, but how much the joints heat up after running continuously all day, how much repeat positioning drifts, how often recalibration is needed—these are what determine whether it can actually stand at a workstation. 450 N·m means heat dissipation and structural load-bearing are both hard problems, and that's exactly what's not on the spec sheet.

There's also something interesting. When I searched for T800, what popped up first was a non-lethal device, a floor scrubber, and a high-end carbon fiber pickleball paddle model, and only further down was the Terminator. One model name shared by so many categories, yet the company making the heavy-load humanoid can't be found with a few actual working-condition feedback posts. That's not entirely their problem, but it also shows that right now what's being discussed about the T800 is still that spec sheet—you can hardly find any logs from running on a production line.

Spec sheets are for telling stories; maintenance manuals are for keeping people. That saying holds just as true for open-source projects. Whether a team is willing to write clear interface docs, calibration procedures, and troubleshooting basically tells you whether they want a one-off demo or a long-term dependency. At this stage of humanoid robots, hardware specs are being pushed fast—450 N·m is high today, but next year it might not be. Whether anyone writes out "what to do after a year of use"—that's where the gap opens up.

So what I'd rather see is whether EngineAI will publish the T800's maintenance cycle, joint lifespan, and calibration docs. Teams willing to write that are usually genuinely preparing for people to put it to use, not just to shoot videos.

Has anyone actually run the T800 continuously in a production line or construction site environment? Any real data on joint temperature and calibration intervals—I'd like to hear it.
