This is my first venture into this topic, and I certainly like some of the designs. One thing though, when it comes to "company" logos and brand names, the more 'adult' or less flashy the logo is, the better and more well received the company is. Take a look at these 36 logos. I'm not going to pretend to know a thing about your universe, but a couple quick notes.
-Almost nobody does handwritten fonts, unless they're catering to a specific clientele (take SMART technologies for example- it's classroom materials for schools, usually elementary and high school)
-Gradients and textures are all but gone in fonts/names (IMB is kind of an exception, but that's not really a texture or a gradient)
-Sci-Fi companies tend to have either sleek or blocky fonts that look futuristic, your Knox Robotics would be a great example of font choice, but texture. Works on the saw, not so much on the font.
It's always a great idea to look at what people in either real or fake industries have done, so here's some companies from the universe of Halo: Liang, Traxus, Hannibal, and Asklon. There's plenty more examples from across the web that you can find too.
The thing I got from these images is that you've got good designs, but the logos for the companies come off as non-serious things. Like, a professional corporation is a company with a logo like this and less like a mom and pop store. Think of these companies more like the people in suits who give power point presentations to 500 people at a time in company briefings and they only use the default solid white slides and Times New Roman.
These are just some helpful tips I've acquired through the years from other Graphic Designers critiquing my own work, and tips I've found across the web. Company logo and graphic design works differently for every genre, but sci-fi is 'held' to nearly the same standards as the real world when it comes to looks.
