I created a series of feats for the themes, including this one.
My game calls the Technologist's Simulacrum "Drone" instead.
Are the options below roughly comparable in value?
What _NUMBER_ should I use to make this a solid worthwhile feat (but not broken)?

Drone Rigger (prerequisites: Technologist background, level 8)

You have designed a variety of upgrades for your drone. You gain _NUMBER_ of the following options:
  • All Terrain: Your drone gains spider climb 20', swim 20', and ignores difficult terrain.
  • Autopilot: Your drone has 2 Intelligence and can follow simple instructions independently. However, it loses immunity to psychic damage.
  • Duplicate: You can build two copies of your drone. Each requires individual operation.
  • Helicopter: 5 times per rest, your drone gains a fly speed of 20' (hover) for 1 minute.
  • Multi-Function: Your drone can replicate up to three of your actions or skills instead of one.
  • Reinforcement: Your drone's hit points and carrying capacity are doubled.
  • Remote Control (prerequisite: spark gap technology): You can command your drone from up to 120 feet away. The drone sends pictures (90 degree view) and audio to you on a tiny handheld display (disadvantage on Perception checks).
  • Shielding: Your drone gains immunity to one damage type: acid, cold, fire, lightning, necrotic, radiant, or thunder.
  • Turbocharger: Your drone's speed or speeds increase to 40', and if it makes its full move in a straight line, it can Dash in that direction as a bonus action.
