My own voice is boring, factual, and sometimes mistaken for a British guy, that's why I was concerned that I would hav etrouble fitting in.
I wouldn't worry about it too much, when you write about robots just let the words come naturally. For example, when I was doing some preliminary research on Towering Inferno to write about it for the site I remembered that the creator built the first version in Lego. That's worth mentioning. Most people use some form of CAD software to fine-tune and measure out parts. This guy used Legos. Just from having this fact and comparing it to how other drivers design and build their robots you can already see how the humor is starting to form. Legos are for kids, it's ridiculous to build a test model of a BATTLEBOT in it. From there the only point is coming up with an appropriate way to present the information that lines the reader up for a punchline/quip, deliver the punchline, and go back to telling about the fight.
Humor in graphical form is like a line graph. You start at the bottom with information. This can be preliminary story or simple background info so the reader becomes familiar enough with the subject to understand what is being talked about. Then the line curves up with the build-up. You mention something that isn't inherently funny, but strange, like an observation or an additional fact that seems out of place. The line hits its apex and you make a joke at the expense of the odd-ball fact/thought. Then the line curves downward as a follow-up joke or funny statement is made (optional) and the reader goes back into getting some additional information to prepare themself for the next joke. Lather rinse repeat. :P
