All I can say is practice practice practice. Get to know your Daw, read the production forum thoughroughly and you will be on the right track in no time.
You say you are finding your own sound and, if that is the case theb brilliant however, I noticed your mention of the whole robot thing.
Without getting into the subject too much I would like to ask you to look around this forum (not just dubs section but elsewhere to). Notice anything? Hopefully you have seen that there is more of those robot noises and stuff of a similar nature than anything else here! This means that the sounds aren't particularly unique or special.
Try not to follow styles, instead use them as inspirational starting points for your own unique creations. Don't stick to one thing either, experiment a lot. Sometimes it will work and others, it won't.
Save every noise you make as a preset. If it doesn't work in one track it might in another. Spend a day just making noises without the intention of making a track, you will then have some ammunition.
Spread your wings mate. Put everything you have into it and one day, who knows, Joe nice might spin your dubs
