Vekks: The home healthcare robot

First things first... rename the project from Vex to Vekks. The name was intended to imply "bother," "harry", "pester", etc., and also sound robot-ish. But I'd forgotten there was a commercial product already on the shelves called Vex Robotics. Oops...

So, same intention in meaning with the change to "Vekks," and a play on the word "vex". I'm sure it'll change again in another iteration.
