Well, in pure energy usage, no; however if you take into account the energy usage of the whole chain, they're orders of magnitude better. After all, they can even be hooked up to a solar panel directly. For us to get 2000 kJ of energy, we need to water plants for a year, transport them, spend more than 2000 kJ of electricity cooking, and that's not even considering raising an animal for x months or years which needs >5000 kJ a day to just exist. Our sun->movement energy efficiency rate is pretty appalling and orders of magnitude worse than a robot's - even if the robot is just hooked onto the regular grid.

    Then you have to also include all of those human energy costs that went into producing the hardware and software for this thing. Mining, manufacturing, assembly, etc.

    There's something very very off with this calculation, because you calculate the whole process of getting the energy for the human part but didn't also calculate the energy needed to build a solar panel which require a factory which require mining which also require transportation. Is the efficiency still better then? I don't really know, but for us human we can just go out and forage some fruits and veggies and fungi without all those modern infrastructure, robot can't forage sunlight.
