Hey just to be clear but there's a difference between enhancements that are dropped from enemies and ones that are crafted in universities. The Invention Enhancements (IO for short) end up outpacing dropped and store bought enhancements. I don't know if you took this under consideration when making your build.
First of all, your minions will need an end redux or two. Two acc, three dam and one end redux is a good rule of thumb. Robots are power hungry. You can easily drop the disorient and tohit debuffs from your minions. It's also not strictly necessary to always triple enhance, as diminishing returns makes the third of a kind much less efficient. Your greatest drain comes from active powers, so try and fit in an end redux there if you can.
You took Aid Other and Resuscitate. Your Protector bots have a heal and Maintenance drone does nothing but heal. In addition, Resuscitate does not work on minions, making the whole pool a little bit of a waste if you solo much. It might be a good idea to instead pick up hover and group fly, for extra defense and because a number of mobs don't have really good ranged attacks.
I don't know enough about Traps so I won't say anything about that.
All said, it's at least a functional build. With force field gen, protector bots, hover and frequent use of seeker drones you can hang around softcap defense, if my napkin math is correct.
