SHOOT!
Here is a tactical customization for your robot companion as a mechanic.
Compensator: Decrease the multi attack penalty for your robot companion to -3 and -6.

Why not weld more on?
Mechanic
The best solution is just more armor! You gain the following new mod.
Up Armor( drone exocortex): Using the tools of just more sheets of metal, you increase the AC of your drone by 2. This stacks with other sources that increase the armor of the drone.

Why not shoot with your friends?
You use the data from one shot to help with the next. When you and your drone both attack the same target in a turn, the second attack, either the drone or yours, gains a +1 circumstance bonus to the attack.

You’re your own best friend!
Advanced Automation
You and your brain are you own best friend!
Prerequisites: Character level 6th, exocortex artificial intelligence
Benefit: When you use your combat tracking ability, you can track a second target. When you use your wireless hacking ability, your computer gains one additional standard action that can only be used by your exocortex to hack the computer.

How about some help for our droid friends?
Your drone is equipped with two robotic arms that can only hold weapons. These arms allow a droid to hold an additional melee or ranged weapon, but no other items or actions can be performed with them. All multi attack and full attack penalties still apply.

How about some love for Starfinder and the Mechanic?
Your exocortex and you work in kind, and sometimes that dual processing power helps you shake things that work against your better self. When you must make a Will saving throw from an effect, roll twice, once for you and once for your exocortex. If either of you save, you are considered to have made the save. You can choose this instead of Memory Module at first level.
