The robot is useful precisely when I’m not home, so having to manually plug in the USB-C cable to charge it kind of defeats the whole point. If the battery dies while I’m away, there’s nothing I can do about it. I said I wanted to build a charging dock so Sentinel could top itself up without me touching a cable.
