Thank you for sharing this video. It can be more helpful for novices than the flat-out adversarial approach of "I'm going to mess this sandwich at every possible step to show you that you need to be precise".

I've found that learners will succeed when they are able to answer affirmatively these two questions: "can I do this?" (self-efficacy), and "do I want to?" (motivation).

The robot scenario with a handful of commands is preferable compared to the "make me a sandwich" task in both respects, because failing badly at even getting bread out of the bag (say) can destroy both self-efficacy and motivation.
