What is the third cable used for?


I am trying to build my own farm bot. While I examine design, I noticed a hole for extra peripheral cable on the utm. But I couldn’t get what is it used for? Is it for making UTM more flexibile for future modifications?

In short, yes.

There are three tube ports on the UTM. One is used for water, one for air (vacuum), and one may be used for other liquids or gases. The current UTM cover has four holes to accommodate these three tubes and the UTM cable (used for electrical connections).
