"AI" is being way, way overused. Robotics does not equal AI. I'm not criticizing you, rembrant. This overuse of AI has worked its way into our common language by a lot of people looking for views and clicks. It has soaked into the lexicon.
It isn't just technical, it is an important distinction. Robots doing something repetitive are programmed by humans with a set of rules, sometimes complicated, that use vision and touch to accomplish the task. They don't change their rules unless the humans change them.
AI, however, has "learning" built into it. The AI finds new rules and employs them. The AI builds new rules. The AI passes those rules onto other AI entities. True AI can throw it all out and start over with a completely different premise and a completely different way of accomplishing the task. True AI will search for new tasks to further the goal.
The analogy with the lemons might be if this robot realized that oranges are similar, but slightly different, and came up with a way to create orange juice and orange zest by modifying its rule set. Of course, it would have to tell the humans to load the hopper with oranges first.
