Yes, both droids and cybernetics are in the works! They are built on the same modular concept as starships and vehicles, but with a much smaller base unit called a microModule (µModule for short).
The basic idea is to be very concrete and have a number of µModules per bodypart that can be filled with different functions. A human will for example have 5 µModules in one arm, and can implant a 2 µModule pop-up weapon doing 1d6 damage. Or increase STR in one arm by 2, by filling 2 (or 4, not sure yet) µModules with synthetic muscular tissue and improved neural connections. Entire body parts can be replaced like this, and possibly allowing for added limbs too.
For robots, there's more like a Base Droid consisting of 10 µModules, shaped somewhat like a trashcan (ie. R2D2), that you build upon. You can either just fill it with functions, or add limbs to get even more µModules. Here's an example I built just yesterday:
STR 5, CON 10, SIZ 5, DEX 5, INT 15, POW 5, CHA 15.
Hit points: 8. Armor: 2. Action points: 2
Total µModules: 10
µModules: Manipulator 2, Communicator 1, Computer Interface 1, Movement (Flight) 3, Compartment 1, Gadget (Welding) 1, Skills 1 (Mechanics 90%, Computers 70%, Knowledge (Psychology) 60%, Astrogation 80%).
Stunts: Luck points 2, Cute/Innocent 90%
Droids as player characters is certainly doable.
The basic rule systems are mainly in place, but there's still some work to do. I need to integrate cybernetics and robotics to play well together, balance the different µModules and of course test the rules much more. Oh, and put them down in legible text.
Regarding gear, I'm not much of a gadgeteer, but I'm sure a few additions can be made.
