Our team redesigned its logo recently, so I have one pointer to give.
You may want to think about an image that doesn't contain words to go with the text.
We went with a rectangular logo that is mostly embellished text (much as you did), but after the fact, we realized that it would be kind of nice to have something a little simpler, without text that we could put places. We are working on throwing together a simpler, more square-shaped (as opposed to rectangle-shaped) design.
This new design could be worked into a part of the robot, our new pit structure, or anywhere else you want to add some art without adding too much complexity (or where you don't have a large rectangular space)
For instance, Wave Robotics worked their logo into the upper sheet metal plates on their Breakaway robot:

(not the best image of it, but it shows what I'm talking about)
This is our current logo:
This was our old logo, before the redesign, we still use it to represent our summer camp and FLL organizations, because changing it might affect the "customer loyalty" that we have been building up over the years.
