The 'robot' isn't the problem. This design is intentional and human made. Here in the Netherlands self checkout is the norm, even in very small grocery stores. However, it's super easy and not frustrating at all, because the stores TRUST their customers. The self checkout is super simple, you scan a product and put it on your bag, or backpack or whatever you have. No need to weigh the scanned products or anything. Nothing overcomplicated.

Now there are some control measures, but they are designed in a way to not be too intrusive or create unnecessary frustration: First, most places have a gate at the exit that only lets you leave by scamming your receipt (or if you go paperless, you scan your membership card on your phone). Also, some places do random inspection. But that's frustration free too - a worker comes up to you with a hand scanner, scans like four or five random items of yours and leaves. Boom, done.
