The simplest way to "remember" a starting position is to make the starting position 0. You can do this using Rest in the Motor Rotation block (1). After your motors have moved (simulated by (2)), you can use a loop (3) to run the motors back to zero. The basic idea though is that if the motor position is negative, then we need to run the motor in the ...

No, it would be practically impossible to damage LEGO pneumatic elements by overpressurizing them. It turns out that LEGO pneumatic pumps actually have a very simple "slip" mechanism that prevents overpressurization. Once the pressure reaches about 35-40psi (the exact threshold varies slightly pump by pump) the rubber plunger disk will give way and bend ...

You wrote you would like to hear an answer that is more definitive as a guess. I guess then we can accept Sariel as a definitive source, and he writes here: There is no risk of anything blowing up. If you’re using Lego pumps, they will simply lack the power to keep pumping once a critical air pressure is reached. There is a risk, however, that your Lego ...
