big difference

Andrew here,

I’ve noticed something.   For each problem we need to decide between using a mechanical solution or a programming solution.  It’s a big difference.

Originally I thought that the He3 pickup would need a programming solution but after some experimenting, I found that it actually needed a mechanical one.  On the other hand, I thought that going over the bump would need a mechanical solution, but I found that it really takes a programming one.    Making the right choice makes a big difference.
