Are they more efficient? It's like saying a jet is faster than a tortoise otherwise.
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.
