This week we double checked our strategy for the experiment in the Eurobot forum with the result that our thoughts are applicable with the rules. But we still have some doubts when it comes to the electron moving by itself and not being moved by the string. So we have developed a second tactic where the electron is static and the string moves the electron by using rolls as seen in the picture. It is not forbidden explicitly in the rules but we want to verify it in the forum just to make sure we stay legal.
