Droid Depot is really easy to find as it’s located right along the main Street in Star Wars Land, across the way from the speeders garage in both Disney’s Hollywood Studios and Disneyland Park.
Droid Depot opens and closes with the Galaxy’s Edge every day, so there are no particular hours, just show up before the park closes and it’ll be open.
Once you select the type of droid you want, you’ll choose from a variety of different droid parts which come to you on a conveyor belt.
Building a droid is simple—follow the directions on the "placemat" or monitor displays to assemble it in the correct order.
Once you’ve completed building your droid, the coolest part of the whole experience is next…activation!
