What should you as a teacher know when the students are trying to achieve a program and robot attachment that could reproduce their behaviour 9 out of 10 times.

Depending on the time that you have you can go for 5 out of 10 or 6 out of 10. The important thing is to direct the students to follow this path of constantly improving the attachment until they reach 9 out of 10 and not to stop before that because stopping before that would be a failure.
As the "Myth busters" say - the difference between messing around and doing science is recording the results. Record the results on a sheet of paper and with a video camera. Inspect the results. Discuss why something is not working and how could it be improved. This is what science is about - doing an experiment, recording a result and building a hypothesis on how you could improve the experiment. In this case the experiment as "building an engineering mechanism for lifting", but it is again a kind of experiment.
I would like to record a small teacher note for doing 9 out of 10 runs in class and some of the rules that you should follow. What we've said currently in the video is to go for 9 out of 10 times but you're in a class or you're in a group of students and you are limited by the time. So, you can go for 5 out of 10 or 6 out of 10 or 7. You can change this number depending on the students, on their experience, on their age, on the time that you have. But it's important to direct the students to build the attachment in a way that the behavior of the attachment could be reproduced. And that's very important. The other thing that you can use an opportunity to teach them is for them to record their results because this is what science is about recording the result and then looking at the results, coming up with solutions for the next step. And while recording the results you can record with camera, you can record on a sheet of paper, on a board. It is important to reach a repeatable very well working attachment.
