Remember that you are not REQUIRED to reach the top row. Although this is a desirable trait, and there are many ways to achieve it, you do not NEED to be able to do this.

It may turn out that being able to score on the two lower racks, repeatedly and reliably... because you got the arm finished a week earlier and had time to tune and test... is more valuable than stressing over reaching the top row.

Of course this is a question only your team can answer, and I encourage you to push the limits of what your resources (mental, physical and financial) allow you to build... but a robot that gets 6 tubes in a row on the bottom rack will always beat a robot that only gets four on the top.

P.S. That said, we are going for all three levels... but I do wonder if we are making the best decision.
